Clematis wilt

IDENTIFICATION — Even if you grow clematis that are very resistant to wilt, next summer your plant may still get it. This common clematis disease is caused by a soil-borne fungus. ?

DAMAGE — Wilt affects the plant almost overnight. It attacks the tip growth and youngest foliage first, and then the stem or the entire plant quickly turns black. ?

CONTROL — Cut the affected growth back, remove all the plant debris and drench the soil once a month for several months with a copper-based fungicide. Wilt won’t kill your clematis; the plant will sprout again from leaf nodes below the soil.
