Hydrangea Mold

Question

I over wintered some hydrangeas in my basement. When I brought them up into the house, several had mold on the leaves. I removed the leaves and placed the plants in a sunny location. Two plants seem to be fine. The third one has slightly curling leaves and mold spots on some of the leaves. What should I do?

Answer 1

It is probably powdery mildew. This is acommon problem on overwintered plants. These articles will help you with that:
