I bought a Dracaena about 3 months ago. I water it 1-2 times a week and make sure the soil is moist, but not too damp. About 3 weeks ago, it started developing a white powdery substance on the leaves. Can you tell me what this is or what I can do to get rid of it?
In lieu of a picture... Here is a blind guess, it is either powdery mildew, a scale bug of some sort, or mineral deposits... Probably a scale bug.
