Question: I have a honeysuckle plant that was doing well until the leaves started to look as if they were sprinkled with white powder. Any suggestions?
Answer: Sounds like powdery mildew. We would need to know more about the environment around the plant and the recent weather to know for sure. You can treat powdery mildew with a natural fungicide such as sulfur spray. You should clean up the area around the plant to allow better air circulation and dry it out. It's also important to get rid of infected stems.
