Cankers (Botryosphaeria) and coral spot kill twigs in the dense crown, especially after drought. Prune out dead wood in dry weather and water through dry spells.
Verticillium wilt
Soil-borne fungus causing sudden wilting and limb death. No cure; remove affected branches and do not replant redbud in infected soil.
Leaf scorch
