Clematis wilt

Botrytis on spent flowers
Grey mould on dead blooms in wet conditions. Remove spent flowers promptly and improve airflow around the plant.
Green flowers (single flush)
The second flush produces single rather than double flowers — this is normal, not a disease or deficiency.
Powdery mildew
White powdery coating on leaves in dry spells. Water consistently at the root zone and apply a fungicide if the problem persists.
Reluctance to establish
