Troubleshooting
Jelena Witch Hazel problems — and how to fix them
Jelena Witch Hazel (Hamamelis × intermedia 'Jelena') 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.
Iron chlorosis
Yellow leaves with green veins indicate iron deficiency caused by high soil pH; correct with acidifying fertiliser or chelated iron.
Coral spot (Nectria canker)
Bright orange pustules on dead or dying branches; prune affected wood to healthy tissue and disinfect tools.
Powdery mildew
White coating on foliage in warm, dry spells; improve air circulation and avoid overhead watering.
Poor or absent flowering
Usually caused by heavy shade, incorrect pruning timing (prune only after flowering), or frost damage to buds.
Vine weevil
Notched leaf margins indicate adult feeding; apply nematode treatment in late summer to control larvae in the root zone.
