Clematis 'Fireworks' problems — and how to fix them
Clematis 'Fireworks' (Clematis 'Fireworks') 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
Rapid wilting of shoots is caused by Calophoma clematidina. Remove and dispose of affected stems; the plant usually regenerates from the base.
Powdery mildew
Especially common in dry summers. Water deeply and consistently at the root zone; apply a suitable fungicide as a preventive in susceptible locations.
Colour fading
The magenta bar can fade in intense afternoon sun. Light afternoon shade helps maintain vibrant colour through the day.
Snail and slug damage
Young shoots and emerging buds are vulnerable in spring. Apply a slug deterrent or biological nematode treatment around the base.
Incorrect pruning timing
As a Group 2 hybrid, it flowers on old wood for the first flush. Only remove dead or damaged stems in late winter; prune lightly after the first flowering for shape.
