Chinese witch hazel problems — and how to fix them
Chinese witch hazel (Hamamelis mollis) 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.
Chlorosis on alkaline soils
Yellow leaves with green veins (interveinal chlorosis) indicate iron or manganese deficiency induced by high pH. Witch hazels require acid soil; apply sequestered iron and amend pH over time. Do not plant in chalky ground.
Slow establishment
Hamamelis mollis is notoriously slow-growing and resents root disturbance. Always plant container-grown specimens; avoid moving established plants. It may take 3–5 years to flower prolifically after planting.
Honey fungus susceptibility
Witch hazels can be susceptible to Armillaria (honey fungus) in soils with infected woody debris. There is no cure; remove and destroy affected plants and replace with resistant species in that spot.
