I planted my rhododendron this spring. Now the leaves have curled and there is like a whitish sort of fuzz on them. What is the problem and what do I do about it?
Sounds like aphids or mealybugs. It may help to treat the shrub with Neem oil. Here is more information: https://www.gardeningknowhow.com/problems/pests/neem-oil-uses.htm
