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

Fungal
Symptoms:

Wilting of leaves on one side or branch of the tree, premature leaf drop, and dark discoloration in the sapwood.

Treatment:

Prune affected branches well below the infected area. Sterilize pruning tools between cuts. There is no chemical cure for systemic infections.
