Troubleshooting
Chinese Redbud problems — and how to fix them
Chinese Redbud (Cercis chinensis) 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.
Canker (Botryosphaeria)
Sunken bark lesions and die-back; prune affected branches to healthy wood, sterilise tools, and improve drainage.
Verticillium wilt
Sudden wilting and yellowing of branches; no cure — remove affected wood or the whole plant if extensive. Avoid replanting Cercis in infected soil.
Frost damage to flower buds
Late spring frosts can destroy the floral display; choose a sheltered wall position and consider fleece protection during sharp cold snaps.
Leaf scorch
Brown crispy leaf edges in hot, dry winds; ensure adequate watering and site away from exposed positions.
Powdery mildew
White coating on leaves in dry summers; treat with a sulphur-based fungicide or improve airflow.
