Chaenomeles, commonly called Japanese quince or flowering quince, is a deciduous shrub belonging to the Rosaceae family and native to China and Japan. Known for its spectacular and early flowering, which often occurs in late winter or early spring, before the leaves are released, it is among the most beautiful and easy-to-grow bonsai trees. The flowers - white, pink, orange or red - sprout on the still bare branches, forming cheerful coloured masses that produce a striking contrast on bare wood. The flowering, always rather generous, can give rise to fragrant ornamental fruits that make the plant very attractive even in winter. It is suitable for almost all styles, especially for rafts.

Location

Chaenomeles bonsai should be kept outdoors all year round, preferably in a sunny position or in light partial shade. To obtain abundant flowering, it is necessary to expose it to full sun. However, it does not tolerate prolonged exposure to the scorching summer sun: during these periods, it may be useful to provide it with light shade. In winter, it tolerates the cold well, but it is advisable to protect it in case of intense or prolonged frost, especially during flowering. It needs good ventilation.

Watering

The common rule of watering whenever the soil feels dry to the touch is also ideal for Chaenomeles, bearing in mind, however, that in hotter periods and in strong winds, it is necessary to water more frequently. In fact, in these cases, the soil often risks becoming completely dry. It is also important to bear in mind that both a lack of water and an excess of water can cause serious imbalances in the plant.

Repotting

Chaenomeles bonsai should be repotted every 2-3 years, preferably in spring immediately after flowering, when it still has energy but has not yet fully developed its foliage. The root system is dense and resistant, but the plant does not like overly severe pruning. About one-third of the roots can be removed, always maintaining a good balance between the roots and the aerial part. The ideal substrate is well-drained and slightly acidic: 50% Kanuma + 40% Akadama + 10% pozzolana.

Pruning

To obtain more intense flowering, allow new shoots to grow without pruning throughout the summer, then shorten them to 2 nodes of the year's growth in mid-autumn. Remove all basal suckers.

Pinching

If you are working on a specimen that is already at a good stage of finishing, pinch the ends of the shoots when they reach a length of 2-3 cm, so as not to ruin the shape. This is a fundamental point of cultivation because, by carefully pinching the shoots, you can obtain a thick, fine external branching.

Wiring

Chaenomeles can be shaped using wire, but care must be taken as its branches are fragile and break easily. In addition, many branches have small thorns, which make the operation more delicate. It is preferable to work on young, flexible branches in spring or fall, avoiding periods of full flowering or fruiting and winter.

Fertilization

Chaenomeles needs balanced nutrients to maintain overall health and support flower and fruit production. It is advisable to fertilize regularly from the end of flowering after pruning every 15 days until October, excluding July and August. During flowering, it is best to suspend fertilization so as not to interfere with the plant's energy balance. In autumn, a fertilizer low in nitrogen and richer in phosphorus and potassium can be used to prepare the plant for winter and promote bud differentiation for the following year. Avoid excess nitrogen, which can reduce flowering.

Care

It can be affected by aphids, quince monilia, collar galls, and bacterial necrosis. Good exposure, aeration of the canopy, and removal of fallen leaves help prevent these problems. It is important to keep the substrate well drained to avoid root rot. The fruits, if present, can be left for ornamental purposes, but it is advisable to remove them before winter if the plant shows signs of fatigue.

The Cercidiphyllum japonicum (Katsura tree) is an excellent species for bonsai due to its rapid growth, heart-shaped leaves, and spectacular autumn color.

Cercidiphyllum, also known as Katsura or “caramel tree”, is a deciduous flowering variety prized for its aesthetic beauty and hardiness. Its bright green, heart-shaped leaves with slightly wavy edges are one of its distinctive features. The foliage changes color spectacularly during the fall, taking on shades ranging from yellow to orange and red. Its small, inconspicuous pink flowers, which bloom in the spring, are dioecious. There are therefore male and female plants: the male plants are distinguished by the delicate scent they emit in autumn, reminiscent of a sweet and spicy mixture that recalls the aroma of caramel. It is a species much appreciated for its ability to take on elegant shapes, thanks to its fine branching and dark brown trunk, which can be easily shaped.

Location

Cercidiphyllum bonsai should be grown outdoors all year round, in a sunny or semi-shaded position. It loves full light, which stimulates vigorous growth, better flowering, and good foliage coloration. It is ideal in a temperate environment, protected from cold drafts. During the winter, it is best to keep it in a sheltered place where temperatures do not fall below 6°C.

Watering

The common rule of watering whenever the soil feels dry to the touch is also ideal for Cercidiphyllum, but bear in mind that in hotter periods and in strong winds, you will need to water more frequently. In fact, in these cases, the soil often risks becoming completely dry. It is also important to bear in mind that both a lack and an excess of water can cause serious imbalances in the plant. More specifically, a lack of water causes the leaves to wilt and stunted growth, while an excess causes the leaves to blacken at the tips.

Repotting

Repotting is carried out every 2-3 years in spring, before the growing season begins, to promote growth and keep the root system healthy. The ideal substrate is well-drained, fertile, and rich in organic matter, with a slightly acidic or neutral pH, to avoid water stagnation and prevent root rot.

Pruning

Cercidiphyllum bonsai has a natural, harmonious growth that does not require much maintenance. Pinching is used to keep the crown compact and stimulate fine branching. When the new shoots have produced 2-4 leaves, you can remove the apical part. Pinching is useful for maintaining balanced proportions between the crown and trunk.

Pinching

Wiring

Wiring Cercidiphyllum is most effective during the growing season, but it must be done carefully without applying too much pressure on the trunk and branches to avoid damage. The wire can be removed after a few months, when the branches have stabilized in the desired position.

Fertilization

Fertilizing Cercidiphyllum is essential to keep it healthy and vigorous. During the growing season (spring and summer, excluding the hottest months), apply a balanced or specific bonsai fertilizer such as hanagokoro every 4 weeks. In autumn, it is preferable to use a fertilizer with less nitrogen and more potassium to promote lignification of the branches and prepare the plant for winter. During the dormant season, it is advisable to minimize or avoid fertilization.

Care

Cercidiphyllum is a disease-resistant plant and is not particularly susceptible to common pests. However, it is important to monitor it for any signs of pests or diseases. In case of aphid or other pest attacks, especially during the summer season, natural remedies or mild insecticides can be used. In addition, this variety likes medium humidity, so during periods of dry air, it is helpful to lightly mist the foliage. The plant is generally resistant to fungal diseases if the soil is not too wet.

The Celtis is an excellent species for bonsai because of its rough bark, resistance and vigorous growth.

Celtis, also known as hackberry, is a deciduous tree belonging to the Ulmaceae family, the same group as the elm. The most common species in bonsai are Celtis sinensis (Chinese) and Celtis australis (European), both of which are characterised by vigorous growth, thin ovate leaves and a good response to pruning. The Celtis is highly valued for its elegant habit, the wrinkled bark that develops with age and the dense branching, which allows for refined structures over time. It is a very hardy plant, tolerates pruning well and adapts easily to different bonsai styles, especially informal upright (moyogi), upside-down broom (hokidachi) and grove (yose-ue). It is an excellent choice for both beginners and experienced bonsai growers, with fast but well controllable growth. It is a species that can be grown outdoors all year round.

Location

Celtis bonsai should be grown outdoors all year round, in a sunny and well-ventilated position. It loves full light, which stimulates compact growth and good foliage coloration. During the summer, in very hot and dry regions, it can benefit from light shading during the middle of the day. In winter, it tolerates low temperatures, but in harsh climates, it is advisable to protect it in a cold greenhouse or in a sheltered position, especially if the pot is small.

Watering

The common rule of watering whenever the soil feels dry to the touch is also ideal for Celtis, bearing in mind, however, that in hotter periods and in strong winds, it is necessary to water more frequently. In fact, in these cases, the soil often risks becoming completely dry. It is also important to bear in mind that both a lack and an excess of water can cause serious imbalances in the plant. More specifically, a lack of water causes the leaves to wilt and stunted growth, while an excess causes the leaves to blacken at the tips.

Repotting

Repotting should be done every 2-3 years, in spring, before the growing season begins. Celtis has a robust and dense root system, which tolerates pruning quite well. When repotting, up to a third of the roots can be removed, but it is always best to do so gradually. The ideal substrate is well-drained. After repotting, it is advisable to keep the plant in a shaded place for a few days, avoiding sudden changes in temperature and direct wind.

Pruning

Structural pruning is carried out in late winter or early spring, before the new shoots appear. At this stage, the line of the trunk is defined and poorly positioned, dry or inward-growing branches are removed. Celtis tolerates vigorous pruning well and often produces new shoots even from old wood. During the growing season, light maintenance pruning can be carried out, especially to correct the direction of the branches and improve the conicity of the branching. In the case of larger cuts, it is advisable to use healing mastic.

Pinching

Celtis bonsai tend to produce long, rapid shoots, especially in spring. Pinching serves to keep the crown compact and stimulate fine branching. When the new shoots have produced 5-6 leaves, you can intervene by leaving only 2 or 3. The plant also responds well to multiple pinching cycles during the growing season. It is important to observe the growth rate: in particularly vigorous years, it may be necessary to pinch more frequently. Pinching is also useful for maintaining balanced proportions between the canopy and the trunk.

Wiring

Wrapping is possible, but must be done carefully and regularly. The young branches of Celtis are quite flexible, but the bark is thin and can be easily marked. Wrapping should preferably be done in autumn or early spring, when there are no leaves and the structure is more visible. For more important settings, wrapping can be combined with pruning.

Fertilization

Celtis is a vigorous plant that benefits from regular fertilization, especially during the growing season. From March to October, it is useful to apply a balanced fertilizer (organic or liquid) every 15-20 days. In the early stages of development, a fertilizer richer in nitrogen can be used, while in autumn it is preferable to switch to fertilizers with more potassium and phosphorus to promote lignification and maturation of the branches. During winter, fertilization is not necessary, nor is it during the summer season.

Care

Celtis bonsai is generally hardy and healthy, but in some conditions it can be susceptible to attacks by aphids, mites, and scale insects, especially if grown in poorly ventilated environments. It is important to check the underside of the leaves regularly and take prompt action with natural remedies or specific treatments in case of infestation. Good exposure, proper watering, and cleaning the pot help prevent problems.
