Q:This year my daylillies ,mini roses and large roses have all developed white spots.I live in the. Northern area .please help.
If the spots look like snow your plants have powdery mildew. You should treat it with a fungicide. I prefer to use a product called ACTINOVATE. Check it out in the Yardener tool shed. Best And Happy Yardening, Nancy
