Blue Ghost Japanese Maple Tree

The Gardening Portal


Position: The Japanese Maple prefers a sunny, airy position but during great midday heat it should be placed in the light shade to prevent damaged leaves. The Japanese Maple is frost hardy even when trained as a Bonsai, but it should be protected from strong frost (below -10° C / 14° F).

Watering: A Japanese Maple in a Bonsai pot must be watered daily in most cases during the growth season, maybe even several times a day during the hottest days, if the soil is well-drained and the tree healthy and vigorous. Use water deficient in lime as the Japanese Maple prefers a neutral or slightly acid pH-value.
Feeding: Especially for mature Japanese Maple Bonsai the use of solid organic fertilizers is well-proven, as it takes effect slowly and gently and generally contains all the required micronutrients. Follow the dosage instructions carefully. If stronger growth is desired, for example on young plants or raw material, you can additionally use a liquid fertilizer weekly. But avoid fertilizers with a very high nitrogen concentration because this would provoke unnecessarily large internodes and leaves.

Pruning: Trimming of shoots and twigs can be done year-round. The pruning of strong branches should be done in autumn to prevent excessive bleeding, or in the summer when callus growth is quick. It is advisable to apply cut-paste as the Japanese Maple is vulnerable to some fungal diseases which can enter through wounds. Cut new growth back to one or two pairs of leaves. Mature Bonsai with a delicate ramification can be pinched in order to keep the twigs thin. After the first leaf pair has unfolded, remove the soft little tip of the shoot between them. This method weakens the tree in the long run and should be applied specifically and thoughtfully. Continue reading about pruning Bonsai trees.

Leaf pruning (the removal of leaves during the growing season) can be done every other year in early summer to encourage smaller leaves. Remove all the leaves, leaving the leaf-stems intact. Partial leaf pruning is more gentle. You do not remove all the leaves, but only the largest and closely spaced ones or you remove the leaves in the strongest areas of the tree. Partial leaf pruning can be done each year as it does not stress the tree as much as total leaf pruning.

Repotting: Repot Japanese Maple Bonsai once every two years and prune the roots efficiently. Root growth is strong and the pot is totally filled with roots after a short time. Use a well-drained soil mixture, for example Akadama mixed with Pumice and lava rock.

Pests and diseases: The Japanese Maple is quite a sturdy tree species. But in spring it is often affected by aphids, which can be eliminated with customary insecticide sprays and sticks to push into the soil.
Verticillium wilt is a fungal disease which can provoke partial or total dying of the Japanese Maple. On fresh cuts you can see black spots in the wood. The disease is hardly treatable and other trees can be infected via the Bonsai tools. You should clean and disinfect your tools if Verticillium is suspected.

Propagation: The Japanese maple can easily be propagated by seeds or cuttings in summer. Air-layering is also a quick and easy propagation method for Japanese Maples.
