I have two hibiscus plants in pots on my patio. For some reason, the leaves and buds keep falling down. I fertilized the plants and watered them more frequently and it seemed to help a little, but now they are sick. On top of the buds and leaves, there is something sand-like all over. Could you tell me what to do?
