Troubleshooting
Clematis 'Rebecca' problems — and how to fix them
Clematis 'Rebecca' (Clematis 'Rebecca') 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
A fungal disease causing sudden stem dieback; cut wilted stems to healthy tissue or near the base. Large-flowered hybrids like 'Rebecca' are most prone, but usually recover.
Overheated root zone
Stress and reduced bloom if roots bake in sun; shade the base with mulch, stones or low planting and keep moisture steady.
Sparse second flush
If light-pruned plants are cut too hard, the early flush on old wood is lost; this group needs only light tidying in late winter, not hard cutback.
Powdery mildew
Appears in still, humid conditions; improve spacing and airflow and remove affected leaves to limit spread.
