Shasta Daisies Have Crystalline Deposits On Yellow Portions Of Flowers

Question From: T. Bates - IDAHO
Q: I have what appear to be crystaline type deposits on the yellow portion of my shasta daisy flowers. This plant is very full and the flowers of this particular plant do not look as healthy as others in my garden. What can I do about the crystals and what is the cause of them?

A: I can't answer that question. Take cutting and and photos to an independent garden center for and accurate ID and control. Best And Happy Yardening, Nancy
