White mildew or mold forming at base of tomato plant
A couple of my tomato plants have died (or are dying). The first sign I noticed of a problem is that near the bottom of the plant, at the soil line, a white mildew or mold is growing. A day or two after noticing the white mold the plants started to die off.
Does anyone know what this is and what I can do about it. So far it has affected 3 of my tomato plants. I really don't want it to spread to my other plants.
