Clematis 'Westerplatte' problems — and how to fix them
Clematis 'Westerplatte' (Clematis 'Westerplatte') 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.
Clematis wilt
Sudden collapse of stems and blackening of foliage caused by the fungus Calophoma; cut affected growth back to healthy tissue or ground level — group-3 types usually regrow from the base.
Hot, dry roots
Reduced flowering and stress occur if the root zone overheats. Shade the base with low plants, stones or mulch and keep soil moist.
Powdery mildew
White coating on leaves in humid, crowded conditions; improve airflow, avoid overhead watering and remove badly affected leaves.
Weak flowering after wrong pruning
As a group-3 clematis it must be cut back hard in late winter; failing to do so leaves leggy, sparse plants that bloom poorly low down.
