Guidelines for Correct Pruning

Brian Green — Mon, 08 Oct 2012 17:20:25 +0000

By Dr. Alex Shigo

Excerpted from “Homeowner’s Guide for Beautiful, Safe, and Healthy Trees,” NE-INF-58-84. At its previous site this page was awarded the Top 5% Award by Point Survey.

Correct pruning is the best thing you can do for your tree. Here are the guidelines:

Natural Target Pruning

Locate the branch bark ridge (BBR)
Find target A — outside BBR
Find target B — where branch meets collar
If B cannot be found, drop an imaginary line at AX. Angle XAC equals XAB.
Stub cut the branch.
Make final cut at line AB (with powersaws make final cut on upstroke.)
Do Not:

Make flush cuts behind the BBR
Leave living or dead stubs
Injure or remove the branch collar
Paint cuts
The best time to prune living branches is late in the dormant season or very early in spring before leaves form. Dead and dying branches can be pruned anytime. Use sharp tools! Make clean cuts. Be careful with all tools. Safety first!

Wound Dressings

Wound dressings do not stop rot! Do Not:

Apply house paints or wood preservatives
Apply heavy coats of any material
Research shows that wound dressings do not stop decay or stall rot. Trees respond effectively to their wounds without the aid of additional chemicals. Do not interfere with this natural process. Keep your tree healthy and it will take care of its wounds. In a short time the wound surface will blend perfectly with the tree bark.

Tree Treatments

Tree Wounds. If trees are wounded, remove injured bark with a sharp knife. Make cuts as shallow as possible. Forming an elongated ellipse is not necessary. Make all margins rounded; do not point tips. Do not enlarge the wound. Do not paint. Do everything possible to maintain health — water, fertilize, prune.

Cavities. If cavities are filled, do not clean so thoroughly that the boundary between decayed wood and sound wood is broken. Fill with nonabrasive materials. Leave for professionals.

Injections and implants. If you plan to have chemicals injected or implanted in your trees, make certain that it is done only by highly skilled professionals. Check injection and implant holes after one season to make certain they are closed. Injection and implant holes should be very small and shallow at the tree base, not in the roots.

If you have any questions or are not certain about what is best for your tree, contact an ISA-certified arborist. Listings are usually available in the Yellow Pages. Or, you can check the ISA’s Online Arborists Directory. Also, see our Consulting Arborists and Commercial Arborists lists for selected Pacific Northwest arborists who provide varying consulting and commercial tree care services. And, see the USDA Forest Service, S&PF, Northeastern Area, SPFO site that includes the Forest Service’s document on How to Prune Trees.

Fall 2012 Newsletter

Brian Green — Tue, 18 Sep 2012 20:35:46 +0000

I would have to agree with all the reports I heard in Portland – we put on a pretty good show! Conditions were perfect for the ITCC, Arbor Market, and Arbor Fair at Laurelhurst Park on the weekend. The educational sessions at the Oregon Conference Center were well attended, and seemed to meet or exceed delegates’ expectations for informative, interesting content. The host hotel put out the welcome mat for us all. The Trade Show was packed at the breaks, so exhibitors were happy. And the Tour des Trees and live and silent auctions raised impressive amounts for the TREE Fund.

The cadre of volunteers (easily recognizable in those very popular neon green tie-dyed shirts) helped everything run smoothly and ensured that our visitors enjoyed their stay in Portland. So to everyone concerned, I’d like to add my voice to the choruses of “Well done, team!” It really was a conference to remember.

This issue contains a few reports summarizing the highlights for those who were unable to join us. Special thanks to Roger Barnett for providing the photos from the ITCC. Upcoming on the calendar is our Chapter’s Tree Climbing Championship, to be held at Washington Park Arboretum in Seattle on September 22 and 23. I hope there will be a good turnout of Chapter members to cheer on the best of our climbers as they compete for the chance to represent us at the ITCC in Toronto next summer.

This will be followed immediately by a shortened (i.e., one-day) Annual Training Conference, which will be convened at the DoubleTree Lloyd Center Hotel in Portland on Monday, September 24.

We recognize that with such a geographically large Chapter, it may be difficult for some members to justify travelling long distances for a single day’s event. But we have to have an Annual General Meeting – and we did the same thing 10 years ago after hosting the ISA Conference in Seattle, and the one-day format worked well – so I look forward to seeing you there!

Also as usual, this issue of the newsletter contains our heartfelt acknowledgement and recognition of the conference planning committee, sponsors, exhibitors, and award winners, reports on the TCC and the Auction, and the AGM minutes.
