Finding white substance in soil and at base of plants
I am really worried that I might have a battle with some kind of plant disease or diseases. I noticed that my oxalis and caladium seemed to have been losing leaves extremely quickly then I noticed a white almost sticky substance at the base of these plants. I removed all the parts that seemed affected and sprayed the roots and they are both looking healthy again. However I am finding alot of this substance on my portulacas and in their soil. I have been removing the affected parts and spraying with a three in one organic insecticide/fungicide/miticide. Yesterday I went into my small greenhouse area and found brown spots on the leaves of several of my plants. I removed all the infected leaves, cut back the plants and sprayed with the same spray. But I am still horrified. What else can I possibly do?
