Care Guide
Watering
Water deeply and regularly during dry spells. Japanese maples prefer moist, well-draining soil and do not tolerate drought or soggy roots well.
Sunlight
Provide partial shade, especially protecting the leaves from harsh afternoon sun to prevent scorching.
Soil and Fertilizer
Plant in rich, acidic to neutral, well-draining soil. Apply a balanced, slow-release fertilizer in early spring.
Pruning
Prune in late autumn or winter when dormant to shape the tree and remove any dead or crossing branches.
Propagation Methods
Grafting
Most common cultivars are grafted onto seedling rootstocks in late winter.
Cutting
Take semi-hardwood cuttings in summer, apply rooting hormone, and place in a high-humidity propagation setup.
Common Diseases & Pests
Verticillium Wilt
FungalWilting of leaves on one side or branch of the tree, premature leaf drop, and dark discoloration in the sapwood.
