Rosemary Bushes Covered With White Foamy Drops

Question From: NEVADA
Q: My rosemary bushes are covered with white foamy drops of something. What might this be?

A:

Probably powdery mildew. Give it a good shower with a stiff stream of water and spray it with Actinovate. Be sure to get the undersides of the needles. Best and Happy Yardening, Nancy.
