Question From: Sheboygan, Wisconsin, United States
Q: This about my 4 year old Hardy Hibiscus. She has lots and lots of buds. Half of them are turning yellow with nothing inside. Please help me!!!!
A: My guess is you have a combination of problems. Too much fertilizer, especially in hot weather. Excessive heat - not much you can do about that. Lack of water. Or, you may have thrips. In that case spray with neem oil when the temperatures cool. Good Luck, Best And Happy Yardening, Nancy
