Troubleshooting
Clematis 'Niobe' problems — and how to fix them
Clematis 'Niobe' (Clematis 'Niobe') 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
Large-flowered hybrids like 'Niobe' can suddenly wilt and collapse. Plant deep so dormant buds below soil can regrow, and cut wilted stems back to healthy or ground-level tissue.
Flower colour bleaching
Intense sun can fade the deep red flowers. A position with some afternoon shade preserves the rich velvety tone while still giving enough light to bloom well.
Hot, dry roots
The roots dislike heat and drought; stressed plants flower poorly and are more wilt-prone. Mulch heavily and keep the base shaded and consistently moist.
Powdery mildew
Late-season white coating on leaves in humid, crowded conditions. Improve airflow, avoid overhead watering and remove badly affected growth.
