Acer palmatum 'Garnet' problems — and how to fix them
Acer palmatum 'Garnet' (Acer palmatum 'Garnet') 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
Crisped, browned leaf margins from sun, wind, or dry roots. Provide dappled shade and shelter and keep the soil cool and consistently moist.
Verticillium wilt
Wilting and dieback of individual branches caused by a soil fungus. Remove affected wood, reduce stress, and avoid replanting maples in infected ground.
Aphids and scale insects
Sap-feeders leave honeydew and sooty mould. Wash off light infestations or use horticultural soap and support beneficial insects.
Container drying and overheating
Pots heat up and dry out fast. Use a large free-draining ericaceous mix, mulch, and water reliably through summer.
