The typical Japanese maple (Acer palmatum) grows fifteen-to-twenty-five feet high, with an equal or greater spread. In the landscape it is grown as a small, single stemmed tree or a large, multi-stemmed shrub. The many different cultivars available through nurseries and garden centers range from six-foot bushes to fifty-foot trees.
How to Grow Japanese Maples
Plant Japanese maples in moist, well-drained garden soil enriched with organic matter. Depending on the climate and the variety, the tree may benefit from some shade and wind protection to keep the leaves from scorching or drying out.
A light annual pruning will help maintain the tree’s size, shape, and general vigor.
Japanese Maple Pests and Diseases
Japanese maples are susceptible to anthracnose, especially in rainy weather. Leaf scorch, caused by draught, leaves brown margins on the leaves. Newly planted trees and trees with limited growing space are particularly vulnerable to leaf scorch. Japanese beetles, scale, and aphids may attack Japanese maples.
Different Japanese maples have different growing requirements and varying vulnerabilities. Growing trees that are known to thrive in your climate and conditions and attending to their needs are excellent ways to reduce insect and disease problems. Your local extension service or nursery can recommend the best Japanese maples for your location.
Depending on the cultivar, the best way to propagate Japanese maples is with softwood cuttings or by grafting.
