Troubleshooting
Clematis 'Warszawska Nike' problems — and how to fix them
Clematis 'Warszawska Nike' (Clematis 'Warszawska Nike') 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.
Colour bleaching
Strong sun can fade the deep purple petals. A spot with some afternoon shade keeps the velvety colour rich while still allowing free flowering.
Bare lower stems
Group 3 pruning leaves the base bare after a hard cut-back. Prune to 20-30 cm in late winter and disguise the legs with lower companion plants.
Clematis wilt
Although fairly resistant, sudden wilt can still occur. Plant deep so buds below soil regrow, and remove collapsed stems back to clean tissue.
Powdery mildew
Late-season mildew may develop in humid, crowded sites. Improve airflow, water at the base, and clear affected leaves.
