Q.White Powder Spreading in Base of Plants on or in Mulch
I have just started noticing a white looking, powdery-like fungus in the mulch around the plants I recently transplanted. It’s only spreading on the mulch and has not gotten on the plant leaves yet. Can you tell me what it is and how to get rid of it?
