Hibiscus Leaf Mold

Anonymous added on September 21, 2011 | Answered

My 2 Hibiscus bushes in my yard (1 borders the lawn) seem to have a massive amount of white mold on the lower leaves. They look kind of like they have spider webs, but I don't see any bugs. The leaves feel sticky to the touch. There is so much of this white powder coming from the bush by the lawn that the street on the opposite side of the bush from the lawn looks like someone poured flour all over it. What is it and how do I get rid of it?

While I cannot be totally sure, the white powder you mention sounds like powdery mildew. However, the webbing and sticky stuff that you speak of sounds more like either mealy bugs or spider mites.
