Acer japonicum 'Aconitifolium' (Acer japonicum 'Aconitifolium') 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 deeply dissected leaves brown at the margins in sun, wind or dry soil; plant in dappled shade with shelter and keep the rootzone moist.
Late-frost damage
Tender new spring growth can be blackened by late frosts; choose a sheltered spot and avoid frost pockets, or protect emerging foliage.
Verticillium wilt
