It self-seeds easily so can spread and become weedy in the landscape. Wind, drought, or underwatering can cause leaf scorch. Temperature extremes in late winter and spring can seriously damage foliage and even younger branches. Insects, Diseases, and Other Plant Problems: Chewing insects and aphids may cause leaf damage. It is suitable for small areas, containers, Asian, and fairy gardens and is often used for bonsai. Plant in partial shade to full sun in moist, well-drained, acid to neutral soil. Known for its shingled leaves, multi-branched form and dense growth, this cultivar is slow-growing and heat-tolerant for a Japanese maple. Acer is Latin for sharp and palmatum means shaped like a hand, referring to the leaves.Įarly in spring its leaves are yellow green, turning medium green in summer and yellow-gold in fall, with the serrated edges of the outer leaves a showy bright red.

Remember the tree buds back everywhere so build the height and trunk first and concentrate on branches in a few years. I would grow the tree as fast as possible to a much larger size - either in the ground or in large pots - feed hard and minimal pruning. The twigs that support the leaves are thicker than normal too - more reason for a large tree and not a little one. ![]() They bud back really well and respond to hard pruning but are very slow growers so take a long time to make into a good bonsai - but they are an unusual bonsai so well worth the effort.Īs the leaves stay large the final tree needs to be large for it to look right - 24"+ finished height can just about balance the leaves - not a shohin tree !Īs it grows slowly you dont want to cut anything off yet or you are setting the project back years. ![]() This thinning is the opposite of other acers - you must remove the 'under leaves' and keep the outer ones otherwise the tree does not grow any more that year. It makes very dense growth with multiple layers of leaves within millimeters of each other, so needs heavy thinning in the upper and outer sections or the tree looses all inner ramification. the tree makes very short annual extension and is very top dominant. Mikawa will retain large leaves all the time - even after total defoliation the leaves regrow the same size.
