Gerbera Daisy Powdery Mildew Indoors: Fungicide Needed

Diagnosis: Powdery Mildew

White grainy crystals on leaves of Gerbera daisies brought indoors for winter are classic powdery mildew—a common fungal issue when outdoor plants move inside.

Treatment

• Apply a systemic fungicide labeled for powdery mildew. Follow label exactly.
• Discard severely affected plants; start fresh next spring.

Improve air circulation and avoid wetting foliage to prevent recurrence.
