Laceleaf Japanese Maple 'Crimson Queen' problems — and how to fix them
Laceleaf Japanese Maple 'Crimson Queen' (Acer palmatum var. dissectum 'Crimson Queen') 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
Browning, crisping leaf margins from too much sun, wind, or dry roots. Move to dappled shade, mulch, and water deeply in heat.
Verticillium wilt
Soil fungus causing sudden branch dieback and internal stem staining. Prune out affected wood, sanitise tools, and avoid replanting maples in infected soil.
Aphids and scale
Sap-suckers leave sticky honeydew and sooty mould on the fine foliage. Hose off or treat with horticultural oil; encourage ladybird predators.
Chlorosis
Yellowing between veins on alkaline soil signals iron lock-out. Acidify with ericaceous compost or chelated iron and avoid lime.
