How to treat powdery mildew in your garden

Symptoms

Our “gogga” of the month for September causes raised, blister-like patches on leaves, powdery growth on the surface of the leaf, flowers may turn white and may never bloom. It’s none other than powdery mildew

What does this mean for me/my plants?

Particularly new soft growth of plants is affected, but the microsopic spores will spread to the rest of the plant if not treated, or if in too much shade and the entire plant will be damaged and die.

Suggested Action

Treat with a broad spectrum fungicide. Remove leaves that are infected and do not add to your compost heap. Visit your local GCA garden centre for advice on the best fungicide for you!
