Q&A – Is there anything I can do to get rid of powdery mildew on my flowers?

Question:
Is there anything I can do to get rid of powdery mildew on my flowers?
​​
Answer:

Control of powdery mildew can be difficult. Kim Rucker, Greenhouse Manager at Dixon Gallery and Gardens says you should separate your plants to increase airflow. Humid nights really encourage the powdery mildew to grow. UT Extension Agent Lee Sammons III recommends planting resistant varieties. UT Extension Agent Chris Cooper names some chemical fungicides you could use, but he also recommends the cultural practices above.
