Question From: Noblesville, Indiana, United States
Q: The ticketed corrosive has white spots on the leaves. It is not fuzzy. Could it be from overstating ?
Your tickseed coreopsis probably has a fungal disease. Neem oil would be a good choice. Use it according to package directions. Read the entire label. Best to spray at sun down or sunup and do not forget the undersides of the leaves. Best And Happy Yardening, Nancy
