USDA Plant Hardiness Zone Map

noreply@blogger.com (countrysidegardener) — Fri, 10 Feb 2012 23:00:00 +0000

A couple of weeks ago the USDA published the latest edition of the Plant Hardiness Zone Map. This is the map that tells us what plants are most likely to thrive in a certain location. The big news about the 2012 map is that the zones have changed by about a half a zone and the USDA has added two new zones—12 and 13. The map is also interactive. You can put in your zip code and it will tell you what zone you are in.

New hardiness zone map

This year’s map is based on weather data from 1976-2005. Each zone represents the average extreme minimum temperature for that zone. The previous map, published in 1990, was based on data from 1974-1986. Of course, the media immediately jumped on this as proof of climate change and global warming. The USDA cautions us not to read too much into these changes, that they are not a reliable indicator of climate change or global warming but that some of the change is simply due to better mapping technology that has greatly improved the accuracy of the map.

So what does all this mean for us folk here in Northern Illinois? Well, don’t plan on planting crepe myrtle or camellias anytime soon. We are still in Zone 5, though we are in subzone 5B. We also should keep in mind that the zones are just a guideline. Each individual garden has its own micro-climates. The spot by the garage that is protected by the wind and gets radiant heat off the exposed foundation might even be a Zone 6 while the low spot toward the back of the garden where cold are can sink could be a Zone 5A. And there are many more factors that impact how well a plant grows in our area including: light exposure, soil fertility and pH, temperatures at both ends of the thermometer, the duration of any particular cold snap (my rosemary held on until just last week in its whiskey barrel by the garage) and the general humidity level. Many plants can adapt to varying conditions but it is important to have the proper conditions and the proper plant for those conditions.

Cold hardiness zones only tell a part of the story. Many plants, especially annuals, also have a hard time dealing with heat. The American Horticultural Society publishes a Heat Zone Map and many plant tags are beginning to carry this designation. The Zone tolerance measures a plant’s ability to withstand some number of “heat days,” or days the temperature goes above 86⁰. According to the AHS we are in heat zone 5, which means we get between 30-45 days above 86⁰.

Birds In Winter

noreply@blogger.com (countrysidegardener) — Sun, 15 Jan 2012 18:42:00 +0000

Birds at feeder in winter

Wow- We finally got some winter last week. As much as I hate shoveling snow it’s nice to get some insulating cover over our plants.. It really helps to protect them from the cold, drying winds and keeps moisture from evaporating from the ground. This is especially important for the broadleaf evergreens that don’t go dormant. If they dry out they will drop the buds that they set last fall and you won’t get any blooms this spring. I noticed that my climbing rose has finally dropped all its leaves and is fully dormant. It is now safe to prune as are any other trees or shrubs that need it.

There are lots of birds that stay around here over the winter including sparrows, nuthatches, chickadees, cardinals, juncos and even gold finches. Most people are surprised that the gold finches don’t migrate since they don’t see them. Actually you do see them its just that their plumage has turned from gold to brown, the better to blend into the environment and avoid predators.

Heated Bird Bath

If you are feeding the birds, make sure you are using a bird feed that is high in energy seeds. These would be black oil sunflower seeds and peanuts. Nyger thistle is also high in energy. Black oil sunflower also has thinner hulls and is easier for the birds to crack open in addition to being high in oil. Suet cakes are also very high in energy and good to put out in winter.

Bird Bath Heater

With this cold weather, any open water has probably frozen over and is not available to the birds. In addition to feeding the birds, you should also put out fresh water. My neighbor Dave has a bird bath out during the summer and the birds use it all summer long. Water is equally important in the winter however. Using a heated bird bath or a bird bath heater will keep the water from freezing in the bird bath. The bird bath heater sits in your birdbath while the heated bird bath is all one unit-- heater and bird bath combined.

Poinsettias-Not Your Grandmother's Poinsettia!

noreply@blogger.com (countrysidegardener) — Sun, 18 Dec 2011 18:29:00 +0000

Poinsettias are a traditional Christmas plant due to their red foliage. They are part of the euphorbia family and have bracts rather than flowers. The flower is the yellow part in the middle of the bract. They can be a tricky crop to grow up in the northern climes mostly due to the need to regulate light. They need to be trimmed to promote a full shape and because in real life they can grow to be over 10’ tall their growth needs to be regulated. Here at Countryside our poinsettias are grown at our growing facility at Garden Valley under natural light. At night all natural light must be reduced, even lights from street lights can throw off their natural inclination to bloom when receiving equal amounts of light and dark. If we have lots of cloudy days so that they are getting more dark than light it not only keeps them from growing but also keeps them from coloring. This year’s crop looks really nice.

ready to help you select the
perfect poinsettia

Poinsettias are really a desert plant native to Central America. The Aztecs used it to make a reddish-purple dye and it was long known as a “Christmas” plant even before it was noticed by Joel Poinsett, the US Ambassador to Mexico in the 1800s. A botanist by training, he sent samples to his home in the US and began breeding them. The rest, as they say, is history.

Poinsettias aren't just red anymore

According to National Geographic poinsettias were the top selling potted plant in 2001. 75 million were sold at a wholesale value of $256 million. Today there are 5 major breeders of poinsettias, the most well known of which is the Paul Ecke Ranch of California. 2/3 of all poinsettias came from the Paul Ecke Ranch in that year.

poinsettias for her house

Through breeding programs there are now over 100 different varieties of poinsettias from which to choose. There are bract color differences (red, white, pink, speckled) leaf color differences (dark green to even a lime green color) and even bloom time differences. My personal favorite pink.

Poinsettias make a great hostess gift and can brighten up a dreary winter with their bright flowering bracts. They should continue to stay in color for many weeks. When you bring them home place them where they will get indirect sunlight for about 6 hours a day. Since they are a desert plant they prefer the soil on the dry side- water only when the soil feels dry and the pot feels light in weight. Don’t panic if the leaves start to drop. This is a natural reaction of the plant to a change in growing conditions. It has gone from our sunny greenhouse to your darker house and is under some stress. Though you may be tempted to water it, don’t. Try finding a room with a little more sunlight.

More Fall Chores

noreply@blogger.com (countrysidegardener) — Wed, 30 Nov 2011 03:07:00 +0000

These pictures are from Wilt Pruf

One of the last chores for the season is prepping broad leaf evergreens for winter. Broad leaf evergreens sounds like an oxymoron. Most evergreens with which we are familiar are the needled variety, such as firs, pines and spruces. These are trees that have adapted to drier climates by having needles instead of leaves. The needles are green and still undergo photosynthesis but have a lot less surface area so that the moisture inside doesn’t evaporate as quickly.
Broad leaf evergreens are shrubs such as azaleas, rhododendrons, boxwood and holly. They really aren’t adapted to our climate or soil but yet we still plant them so we do have a little work to do to keep them happy. Because of their broad leaves that stay on the plant all year they are really susceptible to our drying winter winds. The wind flows over the leaf and just dries them out. This is really damaging for azaleas and rhododendrons because they set their flower buds in the fall. If they get stressed during the winter the first thing they do is go into "survivor" mode and drop the buds in order to protect the rest of the plant.

Azaleas at Uncle Bill's house in MD

To keep this from happening you can wrap the shrubs in burlap or apply an anti-transpirant. There are several anti-transpirants on the market. The most widely available are Wilt Pruf and Wilt Stop. These are organic polymers that make a waxy coating on the leaf so the moisture stays in the plant. You can apply it now and then again around Valentine’s Day. These products can also be used on fresh cut Christmas trees, wreaths, roping and porch pots and they do the same thing as on live shrubs: they keep the moisture in so they last a lot longer without dropping their needles. You can also use these products in the summer when planting or transplanting. The polymer coating helps the plant retain moisture and reduces transplant shock.
Be sure to water your needled evergreens, as well as your broadleaf evergreens, when ever the temperature gets above freezing for an extended period of time. All evergreens continue to undergo photosynthesis and transpire during the winter and they need to replace the water they have lost through this process.

The Northern Lights is the tall
yellow plant in the middle

Here is something to aspire to. This picture on the right was taken at my great uncle's house in Maryland. There they have the right climate and soil conditions to grow great azaleas without really trying. Because of our alkaline soils and harsh winters it is really hard for us to grow broadleaf evergreens, especially azaleas. They do not reliably flower because of the stress during winter. If you really want to grow azaleas try the Northern Lights series. These are azaleas that are deciduous. They survive our winters because they go dormant and drop their leaves. Are they as stunning as the ones at my uncle's? In a word no, but that is the trade off.

Fall Leaf Cleanup

noreply@blogger.com (countrysidegardener) — Sun, 20 Nov 2011 02:42:00 +0000

The last little tomato

I was up on my roof last week blowing leaves out of the gutters with my leaf blower. After I was done I spent a minute looking out over the neighborhood and my own garden and contemplated the summer. Neighbor Ed’s garden was a huge success I would say. Now there isn’t much left except the stems from his tomato and pepper plants and maybe a stray watermelon. I have one little green tomato on my plant that probably won’t be there much longer, especially if we have a hard freeze like they are predicting.
Leaves are a real problem this time of year. So many of them and what do you do: burn them? Bag them? Hope they blow into the neighbors yard? My neighbor down the street rakes them all on to his garden and lets them decompose over the winter and then tills them into the soil. This adds organic matter and nitrogen.

Before the mower...

I am doing something a little different. I have been blowing the leaves onto the lawn and then running them over with the lawn mower. The mower chops them up into dime sized pieces and does a good job of spreading them around. Over the winter they will start to decompose and next year the worms will slowly move the organic matter down into the soil.

Neighbor Dave has been mulching and bagging and so far he’s had about 15 bags of leaves out for the trash guy to take. I haven’t had any bags. I feel pretty good that I have kept a similar amount of leaves out of the land fill and here in my own yard to add to my own soil. I suppose you could make the argument that I used up some gas and caused some pollution by running my lawn mower but I would have been mowing the lawn anyway.

...after the mower

So why is it important to add organic matter to our soil? Well, no matter if your soil is heavy clay soil or sandy and well drained, all soil can benefit with the addition of organic matter. Organic matter breaks up heavy clay soil making it better for plant roots to move through the soil and become established. When soil is too sandy, organic matter helps it retain moisture. Organic matter also slowly changes the soil pH to more acidic, which most plants like. Our soil tends to be too alkaline, which reduces the plants’ ability to take up available nutrients. Adding organic matter to the garden or to perennial beds is easy because we can top dress with compost but getting it into the soil of an already established lawn in more difficult that’s why mulching leaves and leaving on the lawn is a good idea.

I haven’t yet put a winterizer fertilizer on my lawn and I will probably do so next week. The major holidays are a good reminder for yard chores and Thanksgiving is the reminder for winterizer. Putting fertilizer on in the late fall may seem odd since the grass is going somewhat dormant but it actually gets the lawn ready for spring. And Thanksgiving is probably a good time to ready the mower for winter as well.

Fall Chores

Nursery in Lake Como, Italy

I went to Italy last month and as usual I am always interested in seeing what the local horticultural industry is up to. We were in the Naples area and on the train between Naples and Sorrento I noticed numerous greenhouses and hoop houses (like Houses 5-21 at Countryside). Even speeding by at however fast the train was going I saw long stem roses and carnations. It was hard to resist the urge to get off the train to try and find the growing operations. Another crop I noticed growing was chrysanthemums. Our chrysanthemum season is about over but theirs was barely started! I did a little research when I got home and learned the Italy is the third largest producer of cut flowers. They also purchase 5% of all cut flowers. I did stop at a little nursery in Lake Como up by the train station and took a few pictures. I tried in my terrible Italian to explain to the woman working there that I also worked at a garden center but I don’t think I was successful.

Always on the job!

Well, when I left it was the last of summer but I came back to fall and fall chores. If you are still mowing be sure to lower the mower deck a little bit each time you mow. Leaving the grass too long over the winter encourages disease as the grass flops over and doesn’t get good air circulation. It’s not too late for a last feeding of winterizer for the lawn. You could even wait until later this month to do it.
If you are really in the mood for tidying up in the garden, you could cut back the perennials but don’t cut them all the way to the ground. I always like to leave the stems until spring. This gives the snow cover something to stick to and provides insulation through the winter and protects the plant against crown rot.

Rose Collars

Rose Cone

For you rosarians, we recommend using rose collars rather than rose cones. You can put the rose collars on now. They go around the base of the plant and then you fill the collar with top soil. Contrary to popular belief, this does not keep the plant from freezing. What it does is once the ground has frozen it keeps it frozen so that the plant does not undergo a freeze/thaw cycle. Sometimes in January or February we have a bit of a warm up and this can fool the plants into coming out of dormancy. Then we get a hard freeze that shocks the plants and can kill them. If you use rose cones, wait until the rose is fully dormant before pruning it back to fit the rose cone over it. Sometimes this isn’t until after Christmas. If we do get a warm up, remove the rose cone or remove the lid if it has one, so moisture doesn’t build up inside the cone.

And one last thing... Friday, November 11^th is the Countryside Wine Tasting. This is a great event, not to be missed. The Countryside staff will all be there to kick off the holiday season with you. Here's a link to the website with information about all the upcoming holiday events.

Tulip Time

noreply@blogger.com (countrysidegardener) — Mon, 26 Sep 2011 02:28:00 +0000

Crocus are one of the first
bulbs to bloom in spring

It’s officially fall; the days are getting shorter, the temperature is falling and things in the garden are slowing down. I haven’t mown my lawn in over a week, when at the height of summer it was a twice a week chore. Sometimes I am actually relieved when this time of year rolls around.
But, it is not too early to think about next spring and it is the perfect time to plant bulbs. Bulb sales have been declining for several years and it’s mystery to me why. One of my gardening friends thinks it’s because we want instant gratification. We don’t want to plant something now and then have to wait six months before we see it bloom. Well, what ever the reason it is too bad because bulbs are a wonderfully versatile plant in the garden.

Fritilliaries are deer resistant

You can pack a lot of blooms in a small area by "layering" the bulbs, or planting them at different levels based on their requirements. A good rule of thumb is to plant a bulb at 3 times its height. Smaller bulbs like crocus need only be planted maybe 2-3 inches down in the soil while the bigger bulbs such as daffodils or allium need to be planted deeper. And it seems to just work out that the smaller bulbs bloom earlier than the bigger bulbs. There are even bulbs that bloom in the fall! The saffron crocus is one of them, colchicums are another.

The bulb industry has a new ad campaign to show you just how easy it is to plant bulbs. It is called Dig, Drop, Done. Dig the hole, drop in the bulb, and you’re done. You should also be sure to water thoroughly but that doesn’t really go with the alliterative dig drop done theme. I like to naturalize my bulbs, either in the flower beds or in the lawn. I just randomly toss the bulbs in the area I want to plant and then plant them where they land.

Daffodils in bloom

You can fertilize if you like but it really isn’t necessary. The bulb itself has all the energy it will need to grow and bloom the next year. The best time to fertilize is in the spring when you first see the foliage poke up from the ground. After the blooms have faded, resist the temptation to cut back the foliage. This is how the bulb produces and stores the energy needed to bloom next year.

When you buy bulbs make sure to purchase the largest bulbs possible. The bigger the bulb the more energy it has to produce blooms the first year. The bulbs should be also be firm and not bruised. Soft bulbs are dead and will not bloom next spring.

Fox in the neighbor's garden

Yesterday while walking in the neighborhood a fox ran in front of me on Pomeroy Street. He ran into someone’s side yard and sat there long enough for me to take this picture with my phone. He jumped up on a retaining wall and then saw me and took off.

Applying Chemicals

noreply@blogger.com (countrysidegardener) — Mon, 08 Aug 2011 01:17:00 +0000

If it’s not one thing, it’s another. We suffer through drought and heat, and then record rain. The other morning it felt decidedly fall-ish and now the humidity is almost unbearable. I’ve got loads of tomatoes on my plants but none of them are close to ripe. As hard as it is on people, it’s that hard on our plants and our lawns. We need to replenish the nutrients without encouraging too much growth. I’ve seen evidence of Japanese beetles on my roses and hibiscus. And on top of it all we now have diseases to control.
This time of year you need to be careful when applying chemicals. Chemicals are expensive and you want to be sure you get the most out of them. Your plants and lawn should be well watered before you apply any chemical. Chemicals can be stressful even on the non-target plant and you want them to be in the best condition before applying the chemical. Some chemicals work through the vascular system of the plant, like systemic insecticides or most herbicides. If the vascular system is not functioning because the plant is thirsty the chemical won’t work as effectively. In addition, many chemicals require that you not water for a day or two in order for the chemical to be fully taken in by the plant. If the plant or lawn is already dry, another day or two will stress it even further making the chemical less effective. You may think if the weed is going to die any way what does it matter. However if the weed can’t move the herbicide from the leaf to the roots it won’t work. We had a situation at work recently here a customer returned some Roundup because it wasn’t working. He had applied in the heat of July when the weeds weren’t actively growing so the weed wasn’t dying.

Most chemicals should not be applied when the temperature is over 85 . Again, heat causes plants to slow down their growth so the chemical won’t move through the plant efficiently. Over spray onto turf grass when you are trying to kill weeds in the lawn will stress the lawn. Most herbicides are taken in through the foliage by stomas or openings in the leaves. When the temperature rises, plants close these openings to conserve moisture. If the openings are closed, the chemical can’t be taken in.

Apply chemicals in the morning so that the chemical has a chance to dry before the sun hits it. Most chemicals have a petroleum based carrier. Those drops of chemical on the leaf can act like a magnifying glass, burning the leaf. If the leaf is damaged it cannot undergo photosynthesis as effectively. Photosynthesis is what produces the energy for the plant that is stored in the roots and helps the plant survive over the winter. When spraying insecticides, spray early in the morning when bees are not active so you don’t inadvertently kill them as well. Bees in the US have been under attack from Colony Collapse Disorder. Bees are responsible for the pollination of many of our agricultural production and the value of crop pollination is estimated to be $5-14 billion dollars according to a paper published in the Proceedings of the National Academy of Sciences. So do be careful when spraying insecticides as they are not selective and can’t tell a Japanese beetle from a bee.

Organic chemicals have become more popular, especially since more people are growing their own vegetables and herbs. Some of the most popular insecticides are neem oil (from the neem tree), pyrethrins (an extract from chrysanthemums), nicotine, sabadilla and rotenone. Neem oil also has a fungicidal effect. A new product on the market is a bacteria called spinosad which was discovered in the Caribbean in an old rum factory. Diatomaceous earth works great on crawling insects. Essentially it is shells of microscopic ocean dwelling animals called diatoms. Even microscopically the shells have very sharp edges. As the insects crawl over them is cuts them to shreds and they dehydrate. Sounds gruesome. For herbicides, organic controls include food grade oils (garlic, rosemary, etc.) and citric acid, usually in a soy based carrier. Most of these controls only kill the tops of the weed not the roots. They are also non selective, meaning you can’t use them to treat weeds in the lawn, but they are effective in killing weeds in the driveway, walkway, patio, or even in a flower bed if you are careful about overspray. Organic fungicides usually contain sulphur or copper.

Watering the Garden

noreply@blogger.com (countrysidegardener) — Wed, 20 Jul 2011 23:44:00 +0000

I’ve been dragging hoses and hauling watering cans for the past several weeks so naturally this week’s blog is about watering. In my travels around town I’ve seen a few watering "no-no’s."

Neighbor Ed's garden--looking good

First, it takes up to two years for plant material to fully root in so if you have newly planted landscaping make sure they get 1" of water a week. A well established plant and grass can certainly handle a little drought but drought does stress the plants and make them more susceptible to disease even into the following year

Second, water in the morning so that any water that splashes on to the leaves has a chance to dry before evening. This will reduce the opportunity for disease.

Third, water the soil, not the plant. I noticed my neighbor Ed, whose garden is looking quite lush, water with a sprinkler the other evening. Watering from overhead is very inefficient because of evaporation. Water will also splash up onto lower leaves and can invite soil borne diseases such as tomato blight. Watering in the evening also can provide an opportunity for diseases, since they thrive in moist conditions.

Put the hose at the base of the plant
to ensure proper watering

When water trees and shrubs, especially newly planted ones, place the hose right up to the base of the plant and leave it on a slow trickle for awhile. This allows the water to penetrate the root ball from the center and then move out into the surrounding soil and encourages the roots to grow out in the same direction.

And one last thing on the watering front: Lots of people, including me, garden in containers and not just flowers but vegetables as well. I have two whisky barrels that I plant up every year with tomotoes, peppers, eggplant and some herbs every year. If you grow tomatoes in containers it is very important that you water them consistently. Tomatoes require calcium to prevent a problem known as blossom end rot. There is usually enough calcium in the soil from fertilizers to provide enough calcium but if they get too much water so that the calcium is diluted or not enough water so that they cannot pull enough up through their roots you will notice a "water spot" on the blossom end of the tomato. Eventually it turns black and starts to rot. If you notice this happening there are foliar calcium products on the market that you can spray on the plants to prevent it but also remember to water regularly.

Garden Walks

Garden Train with creeping sedum
in foreground

The Garden Conservancy raises money for charity through their "Open Days" program, private garden owners open their gardens to the public. You can go to their website and request to be on their e-mail list to get notices of gardens open in your area.

Another view of trains with
sedum and veronica

Last weekend I went to two gardens in the Barrington area. The first garden has as it main feature garden trains. These "G" scale trains are built for outdoor use. The woman who owns the garden actually has a business designing and installing garden trains called Huff N Puff. In an area the size of my city lot, she had quite a layout with numerous tracks and trains all running at the same time. There was also an indoor display that basically depicted all of Illinois, from down state farms to the city of Chicago, complete with Wrigley Field, Millennium Park and Grant Park.

Non Stop Begonias, salvia
and argeratum

What I found fascinating was her use of annuals in her gardens. It’s rather inspiring to see plants most people can only afford to use in containers being used as bedding plants. She had a whole bed of tuberous (Non-Stop) begonias in full bloom that were gorgeous. It inspired me to stop at Countryside and get a few for my last container. It is mind boggling to think of the number of flats and 4" containers that are needed to fill a garden that size. It must be truckloads.

The second garden was equally as fabulous, though for different reasons. Again, lots of use of annuals for great color punch, but also, as my friend pointed out, several well-placed arbors to give some structure to an other wise flat landscape when you moved away from the house area. One in particular had clematis growing up the arbor and shrub roses along side.

Clematis arbor

Janice also pointed out that even in the shady areas, the turf grass was thick and green. It’s hard to grow grass in shade and in really dense shade we usually recommend putting in some type of ground cover. To do it successfully, you must start with the right type of grass seed mix. Most shady mixes will have very little bluegrass and lots of fine and tall fescues. It’s important not too push the grass by heavily fertilizing as that will just result in tall spindly blades of grass.

We over heard the owner of this property tell another visitor that she has gardeners in Monday through Friday. That’s a bit intimidating so I am perfectly happy with my little lot.

All of this brings me to the subject of our next garden walk, which is next Saturday, July 9^th. It is sponsored by the McHenry County Master Gardeners and is a major fund-raiser for them. This group of volunteers gets special training by the Cooperative Extension Service and must also complete additional training to keep their certificates current. They repay the extension service by volunteering in the extension office in Woodstock and answering homeowner horticultural questions. The garden walk starts at the demonstration garden at McHenry County College and then to 8 other gardens in southern McHenry County. The cost is $17.

Landscaping

noreply@blogger.com (countrysidegardener) — Sat, 25 Jun 2011 14:44:00 +0000

Sometimes the mere thought of re-doing something just makes me want to lie down until the urge passes. Having to make decisions and then do the actual work can be daunting. Fortunately for me I have several friends who enjoy telling me what to do, so at least the decision parts are done for me and all I have to do is the physical part, which can be enjoyable.

What used to be in the raised beds were
a purple sand cherry, euonymous
and some boxwood and holly.
It really didn't do much for me
although it was easy to care for.

So, a couple of weeks ago, at a friend’s urging, I did a little tweaking in the front garden and I do admit the results are quite pleasing. And it really wasn’t a lot of work.

Newly planted impatiens

My parkway tree had some creeping sedum planted around it and it didn’t really provide a lot of color "pop." So out it went– I gave some to neighbor Dave and some to another friend and moved some to the back– and the rest "gasp" I just threw out. It was really quite cathartic. In its place went a flat of colorful Impatiens. Yes, they will have to be replanted every year, but for a few minutes work I will be rewarded with blooms all summer long.

On either side of my front door are raised planter beds but the wall blocks were so high you couldn’t really see the bedding plants until the end of the summer when they had finally grown tall enough. So, we took off the top layer of block and res-set the cap stones and now you can see the pink begonias I planted last month.

The re-purposed arbor

On the right side of my house was a really nice arbor that at one time had clematis growing up the sides. It was too shady so the clematis eventually died, except for one which was struggling. So, we took the arbor apart and used the sides for trellises in the aforementioned raised beds. I replanted the struggling clematis and bought another one (The President) for the other side.

The finished project

So, for just a few hours time and a little cash at Countryside I now have a whole new look at the front of the house. I feel really good about re-purposing the arbor, tho I still don’t know what to do with the arched top.

At Ease Disease, There's a Fungus Among Us

noreply@blogger.com (countrysidegardener) — Wed, 15 Jun 2011 00:34:00 +0000

Powdery Mildew

We’ve had a wet spring and that
means two things—mosquitoes and diseases. It doesn’t matter if it is cold and wet or warm and wet, some disease thrives in it. Some plants are naturally more prone to fungal infections. My monarda get powdery mildew every year and garden phlox are also susceptible. Powdery mildew usually doesn’t do lasting harm, tho it can look a little unsightly. Roses are also prone to many types of disease, including powdery mildew and black spot. Other types of diseases can be devastating to some crops, including tomatoes, squash, and potatoes.

Mosaic disease

Plant diseases are spread in a variety of ways. Sucking insects, like aphids, can transfer the disease and some diseases are spread by spores in the soil. Rose Mosaic Virus is spread through vegetative propagation (cuttings). Some are preventable, most are not treatable.

Late blight on tomatoes

The best way to fight disease is to follow good horticultural practices. Water early in the morning and don’t water from overhead; that is water the soil not the plant. In the vegetable garden, rotate your crops from year to year. Mulch between the rows so soil borne spores aren’t splashed up onto the undersides of the lower leaves when it rains or when watering. If you know you have plants that are susceptible to certain diseases, such as the monarda, or if your vegetables become diseased year after year, start applying fungicides before you see the problem and follow the good horticultural practices outlined above. If you don’t catch it in time, the only thing to do is to remove the affected leaves or stems and begin a spaying program. Dispose of the diseased material by putting it in a bag and then in the trash. Do not throw the diseased prunings in the compost pile. There are organic fungicides that you can use on vegetables and other edible crops, but always, always read and follow the label.

You can also use seed or buy plants that are certified disease resistant. When buying tomato plants, for example, you may see the letters VFNT, or only some of those letters. The V stands for verticillium, the F for fusarium, the N for nematodes and the T for tobacco virus. The Champion tomato variety is certified VFNT, which means it is genetically bred to be resistant to those for pathogens.

Ed's new veg garden

My neighbor roto-tilled up part of his back lawn and put in a vegetable garden. It was an ambitious project that took most of two weekends to finish and now I see rows of something green beginning to sprout.

The vegetable garden at Countryside has been in for several weeks now. This year Richard and Lori have planted potatoes, broccoli, chard, tomatoes, radishes and peppers.

The Countryside Garden

You might think that June is too late to put in a veg. garden but it really isn’t, especially since our spring was so cold and wet. Most of the traditional veg crops do best in warm weather anyway. So, really, now is the perfect time.

Even if you think my neighbor was a little ambitious, many vegetables are easily grown in containers. I grow my herbs and tomatoes in half whiskey barrels where I can position them to take best advantage of the sun in my otherwise shady garden.

our little friends out.

Some vegetables, in particular the leafy chards, beets and lettuce can be interspersed amongst your ornamentals. One year at Ball Seed field days we saw beets used in ornamental annual containers and I just love the look of Bright Lights Swiss Chard in containers. My friend, Jean, does the containers at the Brink Street Market and uses them. Chard is a great alternative to spinach, which has a tendency to “bolt,” or go to seed in the hot weather.

Planting vegetables, even in containers, is a great way to get your kids interested in gardening and interested in eating what they grow. When we lived in Denver I planted pole peas up the one side of our deck. We never had enough for a whole meal but we would use them raw in salads and my girls enjoyed harvesting and shelling them.

If you need some ideas about what to plant, the Cornell University vegetable variety project has vegetables rated by actual gardeners. It is not just specific to New York, but has garden profiles from all over. The University of Illinois extension web site also has information about growing, harvesting and storing vegetables. And, not to brag, but we here at Countryside are a vertible font of knowledge on vegetable growing.

We still have plenty of starter vegetables at Countryside and of course seeds. So come on in and let us help you get started. It’s not too late!

Hummingbirds in the Garden

noreply@blogger.com (countrysidegardener) — Wed, 25 May 2011 23:40:00 +0000

Ruby Throated Hummingbird

Last week while having my coffee and watching the rain I noticed a blur in the hedge next to my house. When it finally settled down on a branch I was surprised to see it was a hummingbird. As they migrate north they send out scouts to look for food sources. There is an overgrown honeysuckle growing in the hedge and that was what it had found. Last summer I had a couple hummingbirds come to the monarda I have planted.

Monarda- A hummingbird favorite

If you want to attract hummers to your garden you can start now by putting out a hummingbird feeder. If the scouts find it they will make it a regular stop on their route. They seem to be quite punctual as every day when I come home from work I see them at the feeder. I make my own sugar mix by heating a cup of water in the microwave and mixing in 1/4 cup sugar.

Trumpet Creeper Flower

You can also plant shrubs and perennials that attract these delightful birds. Plan your hummingbird garden with a variety of plants that begin to bloom early in May and continue to provide nectar through out the summer and into the fall. Yes, as a general rule, they seem to be attracted to red, tubular shaped flowers. Here is a list of plants to consider.

Japanese Beetle Control

noreply@blogger.com (countrysidegardener) — Sat, 14 May 2011 12:53:00 +0000

Japanese beetles love hibiscus!

You might think it is a little early to mention Japanese beetles but if you have plants in your garden that attract the little blighters you need to start planning your beetle strategy. I always say you need a multi pronged approach to beetle control and it helps to understand their life cycle to know which control to use when.

The Japanese beetle emerges from the ground in late June or early July and feeds voraciously on your roses, shrubs, trees and whatever else it can sink its little mandibles into and then they lay eggs in the soil. When the eggs hatch they are called grubs and they then feed voraciously on the roots of your grass. As summer turns to fall, they begin to migrate deeper into the soil to over winter. In the spring they move back to feed and then pupate. At this point they are not feeding, but turning into the beetle that emerges to start the cycle all over again. The upshot is you have two opportunities to kill them– in the grub stage and then as adults– and there are several types of controls available at each stage.

In the grub stage you can use a granular systemic insecticide that you apply and then water in. The grass roots take up the chemical (imidacloprid) and when the grub takes a bite– it dies. If you want an organic control you can use Milky Spore, which is a bacteria that kills the grub. It is available in a concentrated powder that you only have to apply once or a less concentrated granular form that needs to be applied six times over two years in order to build up an effective population of bacteria.

Japanese beetles feeding on leaves

Even if you can control the grubs in your own yard, Japanese beetles can fly several miles to find a mate and to feed, so you will still need to control the beetles at the adult stage. You can spray with Eight® or Sevin®, but they will need to be reapplied every 10-14 days. Or you can use a systemic drench. This is particularly effective if you have large trees that are hard to spray. It is a concentrate that you mix in water and then pour at the base of the tree or shrub. The roots take up the chemical (imidacloprid) and move it up to the leaves at about 4-6 feet a week, depending on growing conditions. The protection last 12 months. If you use it on roses, be aware that the chemical does not go into the flowers, so you will still have to use a contact spray on them.

Black Knot Disease

noreply@blogger.com (countrysidegardener) — Mon, 02 May 2011 00:33:00 +0000

Branches afflicted with Black Knot

My friend Janice called last week to ask about a problem she was having with her ornamental plum in front of her house. It had black growths on some of the branches. I was pretty sure it was some type of fungus, but I didn’t know what or how to treat it. I told her to take a branch into Countryside and ask for KC or Kelly. They are both certified nursery professionals and have training in disease identification.

Kelly O'Leary
Nursery Staff

Well, the diagnosis was Black Knot. Kelly advised her to prune out the affected branches, cutting at least 4" back from the infected sites and to carefully bag the branches and dispose of them. You don’t want diseased plant material going into a compost pile or back in the woods where the fungal spores can continue to spread. After cutting out the infected branches Kelly recommended treating the tree with Bonide Fruit Tree Spray or any spray containing captan.

Black Knot affects plum and cherry trees. The fungus disrupts the twig growth and causes a tumor like growth. At first the swelling is light brown in color but by the second year the swellings have become hard and black. It takes a year or two before the disease even becomes noticeable and by the time you do see indications of the disease, it is usually too far gone for any remedy to work. As with all fungal diseases, it is easier to prevent than to cure.

Close up of Black Knot fungus

The best time to prune out the diseased wood is in the late fall or early winter when the tree and the fungus are dormant. This way you won’t be inadvertently spreading more spores. When you do prune make sure you dip your pruners in rubbing alcohol between cuts to again insure that you don’t spread the disease to healthy tissue.

We got about half way through the job of trimming when we realized that we wouldn’t be left with much of a tree when we were through. Janice decided to just replace the tree with a more disease resistant one. This time she is thinking of a crab apple. Though crab apples are also susceptible to fungal infections such as apple scab and fire blight, new varieties have been introduced that are very disease resistant.

Container Show

noreply@blogger.com (countrysidegardener) — Sat, 30 Apr 2011 00:20:00 +0000

Last night Micheal and I participated in the McHenry Garden Club’s Annual Container Show. We were up on stage with our friends from The Barn, The Gardens of Woodstock, Harm’s Farm and Locker’s Flowers. Shelley Isenhart from Whispering Hills was the moderator.

Micheal at the Container Show

Mike and I made 8 containers and all the containers made were raffled off to members of the audience. It was a fun evening that showcased the talent available to you at our McHenry County gardens centers.

Moderator Shelley

We all had the opportunity to make a few comments about our designs and Mike offered some design advice about the use of contrast in designing a pleasing combination. Contrasting foliage and flower texture and color helps make each individual plant stand out in the container.

Shelly talked about the three basic design elements in container gardening being the thriller, filler, spiller—choosing plants that are tall for the “thriller,” semi-trailing or mounding for the “filler,” and trailing plants to soften the edges of the container.

Some of the containers
we made last night

Many of the containers used a lot of annuals but also incorporated perennials including roses, a Japanese maple, a blueberry shrub, heucheras, lamium, and even plants we usually think of as indoor houseplants.

The Barn used miniature conifers in their fairy gardens and accented them with scale versions of garden accents. (Be sure to congratulate Heather next time you are there on the upcoming birth of daughter number 2, due this fall.) Locker’s Flowers used children’s pails as containers and sea shells as soil cover, to add come whimsy to their designs. Harm’s Farm did several containers with vegetables and herbs for containers that are fun and functional.

So, a big thank you to the McHenry Garden Club for sponsoring this fun evening. To learn more about garden clubs in our area contact the National Garden Clubs at www.gardenclub.org.

The Year of the Tomato

noreply@blogger.com (countrysidegardener) — Wed, 27 Apr 2011 00:03:00 +0000

Topsy Turvy tomato

A couple of weeks ago my youngest, who is in school in Boston, called to ask about growing tomatoes in one of the Up Side Down grow bags. She asked if they started tomatoes from seed would they bear fruit this year. Well, apparently, I have been neglectful of her horticultural education (tho I may say that she is getting a first rate education in information science and it has been worth every penny Mr. Ross spends to send her there). Of course tomatoes are an annual here and even if you could over winter them, the likely hood of survival and then good production the next year is doubtful.
The National Gardening Bureau has proclaimed this year the Year of the Tomato. They have also selected the Zinnia as the Annual of the Year and next year will also honor a perennial.

Tomatoes can be classified in several ways, including by size and shape of fruit, growth habit, color, days to maturity, etc. Everybody has an opinion on which is best, but it really depends on how you are going to use it, to determine what tomato is best for you. There are plenty of hybrids and heirlooms to pick from so you shouldn’t have a problem finding one that suits your needs.

Tomatoes in a mixed container

Tomatoes range in size from grape, cherry, plum, standard and beefsteak. They can be red, orange, yellow, green, almost black and even striped. One important factor in determining what variety to grow is its growth habit. I always grow mine in a big whiskey barrel so I usually pick a “determinate” variety. This type of tomato grows to a genetically predetermined height and bears most of its fruit at the same time. This is a good thing if you do any type of canning or preserving of tomatoes. Determinate tomatoes tend to be more compact, which makes them perfect for containers. Some of them are so compact they can even be planted in hanging baskets! Indeterminate types continue to grow and produce fruit over the entire season. They can get quite large and need staking or a tomato cage to hold them up.

There are a bazillion
tomato varieties

One question we always get at Countryside is about the days to maturity and what this actually means. Tomatoes are classified as early, mid-season and late. Days to maturity are the average days from the time the plant is transplanted into the garden until the first fruit ripens. Since it is an average, it really should be used as a guide not gospel. Generally speaking early tomatoes will ripen in fewer than 70 days, mid-season from 70-80 days and late tomatoes will require over 80 days from date of planting outdoors.

We always have a great selection of all types of tomatoes and I am sure we can find one that will suit your needs. Click here to see all the varieties we will have this year.

Ideas for Spring

noreply@blogger.com (countrysidegardener) — Wed, 20 Apr 2011 00:13:00 +0000

Pansy bowl with snow!

I am really getting eager to start planting, but what a surprise this morning’s snow was! Your pansies, violas, snapdragons, and other cool season annuals will have survived just fine but please do remember that the last frost date for our area is May 15th. Warm season veg crops and annuals will have to wait! My friend Janice sent me this picture of her pansy bowl on Monday morning!

Giant double zinnias

I do tend to be a creature of habit and try to stick with what I know works, but it is fun to change things up once in a while and I plan to do that this year in my annual beds. For the last several years I have planted wax begonias in the shady back beds and salvia in the sunny front beds. I haven’t been happy with the performance of the begonias, tho that could be a function of watering. This year I think I will use impatiens in the back (and remember to water more frequently) and put the begonias up front. They really do work well in sunny areas, though most people use them for shadier spots.

Zinnias in containers

If you are thinking of doing something different this year, the National Gardening Bureau has proclaimed 2011 “The Year of the Zinnia.” There are some plants that are so common we often forget about using them. I think zinnias fall into that category. They are truly an “old fashioned” annual that most people remember from Grandma’s garden. They are easy to grow from seed, come in a variety of heights and colors, and make an outstanding flower for the cut flower garden.

Sadly, the cut flower garden is becoming a thing of the past. We are using annuals as more of a ground cover plant or in containers rather than as a tall, stately garden flower and we don’t want to deadhead. Well, fear not. The plant breeders of the world know this about us and have bred some zinnias just for this purpose. The “Profusion” and “Zahara” series fill this bill perfectly. The Zahara series was an AAS (All America Selection) 2010 selection for its larger flowers and many color variations.

Zahara Zinnias

Zinnias have been given the AAS designation because they are easy to grow, disease resistant and grow well in a variety of conditions. They come in a variety of heights, colors, and flower forms. They need at least 6 hours of sun and, while they are not heavy feeders, they should be fertilized at least twice during the growing season. They perform well in hot weather but don’t forget to water them.

Grassy Weeds

noreply@blogger.com (countrysidegardener) — Sun, 10 Apr 2011 21:55:00 +0000

Crabgrass

I hope everyone enjoyed Garden Fest at the college yesterday. Kim gave two presentations and I gave on on watergardening. Next weekend we will have several seminars at the store so drop by to find out about the best new plants for 2011 and dealing with insects.

With the warmer weather I have been out looking at my lawn. I have a bird feeder in my yard and it seems I also have a lot of grassy weeds. I am sure there is a connection. Neighbor Dave next door has also noticed more "crabgrass" and I had to fess up that I thought it was because of my bird feeder. We both enjoy the birds so I guess that is a tradeoff we have to make.

Dandelions are broadleaf weeds

It's easy to kill grass in an ornamental bed or to kill broadleaf weeds in the lawn because they are completely different in their makeup and don't react to the herbicides in the same way. It is much harder to kill broadleaf weeds in an ornamental bed without affecting the ornamentals or to kill grassy weeds in the lawn. One way is to get to the weeds before they germinate. We call this preemergent weed control. The trick to being successful at pre-emergent control is to get the herbicide down before the weeds germinate. Most crabgrass seeds germinate when the soil temperature reaches 55F. You need to get the herbicide down a week or two before this happens. With our fluctuating temperatures in the spring this is hard to do. A visual clue to timing is the forsythia. When you see the forsythia in bloom it is time to put down the pre-emergent. By the time the lilacs bloom, it is too late.

Corn Gluten

For those of you looking for an organic control, try corn gluten. University studies have shown that corn gluten inhibits root development in germinating seeds. As an added benefit it also has 9% nitrogen and makes an excellent fertilizer. The product needs to be watered in after applying it and then needs a dry period. Try to pick a day when no rain is forcast for the next couple of days and then gently sprinkle with a hose to get the product wet. If it rains, the product will become too dilute and the seeds with be able to recover and continue to grow. Apply the corn gluten at a rate of 20-40 pounds per 1000 square feet. For best results apply twice in the spring and again in the fall.

Pre-emergent herbicides do not discriminate between "good" seeds and "bad." If you are planning to overseed your lawn wait at least six weeks after applying the pre-emergent.

Spring Is Finally Here

noreply@blogger.com (countrysidegardener) — Sun, 03 Apr 2011 18:20:00 +0000

Crocus in lawn

Spring Is Finally Here!

The crocus in my front lawn are up and blooming and the daffodils are not far behind. Last fall I planted more crocus in the back but it is shadier there and hence cooler so no sign of them yet. I hope the squirrels didn't dig them up. I do occasionally find blooming bulbs not where I planted them. But that is okay because I naturalize my bulbs in the grass as well as designated flower beds so what could be more natural than bulbs planted by squirrels.

Naturalized scilla

A few years ago I planted scilla in the middle of the front lawn. I just love those houses on Woodstock Street near Oak where the scilla has truly naturalized in the front lawns. What a sight. You should drive by and see it. Mine hasn't done so well and I will have to remember next fall to add more. I meant to do it this year, but by the time I got around to it the stores were sold out.

Well, what better way to begin another gardening season here in Norther Illinois than by attending Garden Fest next Saturday at McHenry County College. GardenFest is sponsored by the Master Gardeners of McHenry County, part of the University of Illinois Extension Service. With all the funding cut backs going on this is one way to help support a group that gives so much to the community. If you ever have a gardening question and call the Extension Office in Woodstock, it will most likely be a Master Gardener that answers it. They get extensive training from the Extension Service and in return volunteer time at the office to answer garden related questions.

Kim Hartman and I will be there as speakers-- I am giving a talk on water gardening and Kim's topics are shade gardening and roses. Kim's are at 9:30am and 1:15 and mine is at 2:45.

Also going on this month, in fact as we speak, is the Macy's Flower Show at the Macy's on State Street. I can't get there this year but I have gone in the past and the floral displays are outstanding. Again, they also have classes and the Cook County Master Gardeners are there to answer any questions.

And, finally, on April 16 Countryside is having another full day of seminars on gardening. Kim will be filling you in on the best new plants for 2011, Karen Campney, Nursery Manager, will be talking about growing fruit and a tree specialist will be teaching you about insect management in trees, including how to deal with the emerald ash borer.

Get Ready for Winter

noreply@blogger.com (countrysidegardener) — Wed, 13 Oct 2010 00:43:00 +0000

Now is the time of year to prepare the garden for winter. As much rain as we got this spring and summer, that is how dry it has been this fall. Plants prepare for winter by transporting the energy produced in the leaves down to the roots and they need water to do this. If you did any new planting this summer be sure to give those plants a good drink of water. Don't assume the rain we are supposed to get tomorrow will be sufficient. I have been dragging the hose around the garden for the last week making sure all my plants have adequate moisture. I even watered the lawn, which I never do, because it is just so parched.

Besides getting ready for winter we can also prepare for some spring blooming by planting bulbs. Bulbs seem to go in and out of fashion and you can tell they are currently out of fashion by the limited availability in the garden centers. I don't know why that is because they really are a good value, especially when compared to buying them already in bloom next spring. I like to "naturalize" my bulbs by planting them to look like they would in nature. I don't plant them in rows in a border. I plant mine in the lawn and in clumps in and among my perennials.

Bulbs are not hard to plant. They should be planted at a depth 3x the height of the bulb. Small bulbs, like crocus and scilla, are planted just an inch or two below the surface of the soil, while larger bulbs, like tulips and daffodils should be planted much deeper. This ability to plant at different depths allow you to layer the bulbs and you can actually plant enough different types of bulbs in a small area to have blooms from April through June.

If you planted bulbs last summer, you might have planted gladiolas, cannas or dahlias. These bulbs are not hardy in our area and need to be dug up, dried, cleaned and stored in a cool, dry place until they can be planted next spring.

More on Organic Lawn Maintenance

noreply@blogger.com (countrysidegardener) — Tue, 24 Aug 2010 00:03:00 +0000

Organic fertilizers and good horticultural practices are only two aspects of organic lawn maintenance. You may still have weed and insect issues to contend with.

Weeds

Organic week control in a lawn is a problem because there are no selective organic controls, such as a broadleaf weed killer that only kills broadleaf weeds. Organic herbicides are made from horticultural strength vinegar (usually a 20% concentration compared to a 3 % concentration for what we use in the kitchen) or horticultural oil extracts such as oil of thyme, mint or rosemary. They are non-selective (think Roundup) and will kill any vegetation they come in contact with. They work best in a flower or perennial bed where the ornamentals can be protected from any over spray. In a lawn, the most organic method is to pull them by hand.

Pre Emergent Weed Control

Preventing weeds from germinating in the first place by using a pre emergent herbicide, is one way to limit weed growth and here there is an organic alternative. The ability of corn gluten to inhibit root growth was discovered at Iowa State University in the early 1990s. It has been growing in popularity ever since. It is a bit tricky to use and get good results. Timing is critical. Several companies package corn gluten, including Bradfield Organics. Make sure you are using 100% corn gluten. Apply it at the rate of 20 pounds per 1000 square feet about 4-6 weeks before the weeds are expected to germinate. This is the tricky part. Most seeds germinate when the soil temperature is between 68̊–86̊ degrees fahrenheit but trying to estimate exactly when that will happen when the weather is so variable here in Northern Illinois is hard. Also, if it is too rainy during the germination period the corn gluten gets diluted and is not effective. On top of that, corn gluten contains about 10% nitrogen and makes an excellent fertilizer so you may actually end up with a bumper crop of weeds!

Insects

By far, grubs are the biggest insect issue for turf. Grubs are just one stage in the life cycle of many types of insects, including some moths and certain beetles such as Japanese beetles.

We did not experience a huge Japanese beetle outbreak this year here in my part of Crystal Lake. They do seem to be somewhat cyclical, so I am guessing that over the next few years we will see populations build back up. The best time to kill grubs is in the juvenile stage, which is to say mid-to late July. There is also an organic alternative for grub control.

Milky spore is a bacteria that the grubs ingest as they are chewing on the roots of your lawn. The bacteria then kills the grubs. Milky spore comes in two forms– a concentrated powder that you apply with a tube that looks like a giant Parmesan cheese shaker , and a granular form that is not as concentrated but is more easily applied with a drop spreader. It is not an immediate cure as it takes several years for the spore count to reach a critical mass.

Fungi

The most common lawn fungi are powdery mildew, red thread, pink patch and rusts. The University of Illinois does not recommend fungicides on home lawns. Instead use the good horticultural practices that we have talked about. Most fungal diseases occur in shady areas where the grass is not as healthy. Plant appropriate shade tolerant grasses in shady areas, or better yet, replace the lawn with shade tolerant ground covers or a shade perennial bed. Water early in the morning and water deeply and infrequently. Make sure the lawn is healthy through a good fertilizer program. Healthy turf is better able to withstand turf diseases.

Using Garden Chemicals

noreply@blogger.com (countrysidegardener) — Tue, 27 Jul 2010 02:06:00 +0000

Organic lawncare is less expensive in the long run but sometimes you have diseases or insects that require a chemical control or the weeds are running rampant and you just need to deal with them. Garden chemicals are expensive but if you use them correctly they will be alot more effective and won't cost as much to use.

Before you spray make sure the plants, even the target weeds, are thoroughly watered in. For the weeds, you want them actively growing so that they will take up all and use the herbicide more effectively. Onamentals and vegetables should be actively growing so that they can withstand the stress of having chemicals applied to them. Many chemicals require some period of no rain or water for the chemical to work its way into the plant. If the plant hasn't been watered before chemical application it may become stressed from lack of water.

Always spray when it is cool and expected to stay cool for a few days after application. For herbicides this is especially important because plants take in the chemical through pores in their leaves. In the heat these pores close up and the herbicide cannot be taken in by the plant. Also, plants tend to slow down their rate of growth in the heat so if they are not actively growing they are not actively dying. Leaves have a waxy coating or even a coating of dust that also impedes chemical takeup. You can add a "spreader/sticker" to the chemical mixture that cuts through this wax and dirt and again increases the chemical's effectiveness.

Spray early in the morning so the chemical has time to dry before the sun hits it. The beads of liquid can act like a magnifying glass and burn the leaves. Spray when the wind is calm so that you don't have spray drift and accidently take out some of your perennials when you were spraying for other broad leaf weeds.

As always read the label and make sure it will treat the problem you have. If you have questions about any chemical stop by Countryside and ask one the ICN professionals to help you determine what the problem is and how best to treat it. And follow the label directions--more is not always better.

Blossom End Rot

noreply@blogger.com (countrysidegardener) — Sun, 18 Jul 2010 18:29:00 +0000

I was really bummed this week to discover that some of my tomatoes have blossom end rot. I have probably pitched 7-8 tomatoes. I grow my veggies and herbs in containers because I don’t have a lot of room where there is full sun. I was really happy this spring to discover that the thyme had survived the winter and I replanted the rosemary I had taken inside last fall and it has done really well. This year I planted a bush Early Girl and it has grown and produced quite a few blossoms that will eventually turn into tomatoes.

Blossom end rot pretty much tells you what the disease does in tomatoes. The blossom end turns black and eventually the whole tomato rots. It is caused by a lack of calcium and is due to irregular watering. Too little water and the plant cannot take up enough calcium, too much and the nutrients are diluted. I think it is exacerbated in container gardening because there is only so much soil to hold water and nutrients and the roots can only go so far before they reach the side of the container. When the tomatoes are in the ground at least they can send the roots farther out to search for nutrients and water.

The most immediate remedy (besides correcting the water issue) is water soluble calcium that you can spray on the leaves of the tomato. It is available at Countryside and is called Blossom End Rot Stop.

Planting tip: If for some reason you are having to plant or transplant in this heat, use an anti-transpirant such as Wilt Stop or Wilt Pruf. This will keeps the plant from losing moisture and will make your planting more successful. Plants need about an inch of water a week and prefer to be watered deeply and infrequently rather than frequent shallow waterings.
