Japanese Maple 'Dissectum' problems — and how to fix them
Japanese Maple 'Dissectum' (Acer palmatum var. 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
The fine dissected leaves brown at the edges fastest in sun, wind, or dry soil. Plant in dappled shade with shelter and keep the root zone evenly moist and mulched.
Verticillium wilt
Soil-borne fungus causing branch dieback and dark wood streaking. Cut out affected stems, disinfect tools, and do not replant a maple in infected soil.
Dieback in containers
Grafted laceleaf forms in pots suffer if the rootball dries out or freezes solid. Use a large container, water consistently, and protect roots from hard freezes.
Aphids
Colonies on new shoots cause distorted growth and honeydew. Tolerate small numbers, rinse off with water, or encourage natural predators rather than spraying.
