Troubleshooting
Japanese Maple problems — and how to fix them
Japanese Maple (Acer palmatum) 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
Hot sun, wind, or dry soil browns and crisps the delicate leaf margins; site in dappled shade with shelter and keep moisture even.
Verticillium wilt
A soil fungus causing branch dieback and wilting; prune out affected wood, avoid wounding roots, and don't plant where wilt has occurred.
Late-frost damage
Tender spring growth is nipped by late frosts; site away from frost pockets and protect emerging leaves if frost threatens.
Aphids and scale
Sap-suckers produce sticky honeydew and sooty mold; treat infestations early with appropriate controls and encourage natural predators.
