Armand's Clematis problems — and how to fix them
Armand's Clematis (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.
Wind scorch
Large evergreen leaves are vulnerable to cold, drying winds; plant in a sheltered, south-facing position against a wall.
Clematis wilt
Less common in evergreen types but can occur; prune to healthy growth below the wilt line and feed to aid recovery.
Scale insects
Brown waxy scales on stems and leaves; treat with horticultural oil spray in late winter before growth begins.
Frost damage to flower buds
Early flowers may be caught by late frosts; protect with horticultural fleece during late-season frost events.
Poor flowering
Usually caused by incorrect pruning — Clematis armandii is a Group 1 clematis; prune only lightly immediately after flowering, never in autumn or winter.
