Clematis armandii problems — and how to fix them
Clematis armandii (Clematis armandii) 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.
Wrong-time pruning kills the display
As a Group 1 clematis it flowers on the previous year's growth. Hard pruning in winter or spring removes the flower buds, so only tidy lightly straight after flowering.
Frost and wind damage
Evergreen foliage and early flowers are vulnerable to hard frosts and cold winds, which scorch leaves and ruin buds. Site it in a sheltered spot against a warm wall.
Clematis wilt
Less prone than large-flowered hybrids, but stems can suddenly collapse from fungal wilt. Cut affected growth back to healthy tissue and keep the base mulched and watered.
Outgrowing its space
Extremely vigorous and can swamp smaller supports or neighbouring plants. Give it a large, robust structure and thin congested growth after flowering.
