hibiscus

Question

I have six hibiscus plants on the patio around the pool. Three of them have white mold on the stems and buds. What do I do about this?

Answer 1

This could be Powdery Mildew. Treat your plants with Neem Oil.
Powdery Mildew is often caused by damp conditions and lack of air circulation.
