Clematis 'Perle d'Azur' problems — and how to fix them
Clematis 'Perle d'Azur' (Clematis 'Perle d'Azur') 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
Suddenly wilting and blackening shoots are the sign. Prune back to healthy tissue at or below ground level; recovery is usually good. Hard Group 3 pruning reduces wilt impact.
Powdery mildew
A particular issue in dry summers on this cultivar. Water at the base consistently, avoid overcrowding, and apply sulfur-based spray preventatively if mildew has been a recurring problem.
Aphids
Soft new growth attracts aphid colonies in late spring. Blast off with water or apply insecticidal soap. Natural predators (ladybirds, hoverflies) usually arrive quickly in a wildlife-friendly garden.
Poor or late flowering
Always hard prune in late winter (late February to early March in UK). Leaving old stems reduces flowering significantly on this Group 3 cultivar.
Slugs and snails
Emerging shoots in spring are vulnerable. Use organic pellets or copper tape around supports and the base of the plant.
