Troubleshooting
Acer palmatum 'Dissectum' problems — and how to fix them
Acer palmatum 'Dissectum' (Acer palmatum 'Dissectum') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Leaf scorch
Browned, crisped leaf edges from sun, wind, or dry soil. Plant in dappled shade with shelter and keep roots cool and consistently moist.
Verticillium wilt
Branch wilting and dieback from a soil-borne fungus. Prune out affected wood, minimise stress, and avoid replanting maples in infected soil.
Aphids and scale
Sap-suckers produce honeydew and sooty mould. Hose off light infestations or treat with horticultural soap and encourage predators.
Container stress
Pots overheat and dry out fast. Use a large free-draining ericaceous mix, mulch the surface, and water reliably in summer.
