Troubleshooting
Shohin Japanese Maple problems — and how to fix them
Shohin Japanese Maple (Acer palmatum 'Kiyohime') 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
Brown, crispy margins from too much sun, wind or under-watering. Move to morning sun and afternoon shade and keep the rootball evenly moist.
Apex dieback
Strong upper growth shades and weakens lower branches; 'Kiyohime' apexes can die back if left unchecked. Thin and weaken the top to keep the spreading form.
Verticillium wilt
A soil-borne fungus causing sudden branch wilt and dieback. Remove affected wood, sterilise tools, and improve drainage and vigour; there is no chemical cure.
Aphids
Cluster on soft new shoots, distorting growth and dropping honeydew. Hose off or treat with insecticidal soap early in the season.
