How to Grow and Care for a Japanese Maple
The short answer
Japanese maples do best in dappled or afternoon shade in moist, well-drained, slightly acidic soil rich in organic matter. Full hot sun — especially with dry soil — scorches the foliage, so an east- or north-facing spot with shelter from wind is ideal. They range from 6-foot laceleaf mounds to 25-foot small trees, so match the cultivar to the space.
Water generously while establishing (every couple of days at first, tapering to weekly through the first season), mulch a wide ring to keep roots cool and moist, and prune only lightly: structural cuts in late winter while dormant, fine aesthetic pruning in late spring after leaf-out.
Siting
- Dappled shade or morning-sun/afternoon-shade; hot dry sun = leaf scorch.
- Moist but well-drained, acidic soil high in organic matter.
- Shelter from strong, drying winds; east and north exposures work well.
- Sizes run 6-25 ft depending on cultivar — check the tag before planting near structures.
Care
- 1Water to establish — Every 1-3 days right after planting, tapering to about weekly through the first growing season; keep established trees watered in drought.
- 2Mulch — A wide 2-3 inch ring keeps the shallow roots cool and moist — kept off the trunk.
- 3Prune lightly — Structural pruning in late winter (dormant); fine shaping in late spring after leaves harden. Japanese maples need little pruning — don't shear.
→ Crispy brown leaf edges in summer are usually scorch (sun/wind/dry soil), not disease — fix the siting or watering before suspecting anything else.
