Boy did it stink!
Yesterday I went ahead and baked my potting soil. I use Garden Safe potting soil. I guess it's ok, but I noticed with the last bag I purchased that I would get these tiny, crawling light colored insects in the soil. Sometimes they'd crawl on top of the soil. Sometimes around the drainage holes. I don't think they hurt anything and I don't know what they were called. Allowing the soil to become really, really dry (as dry as the plant could stand it) seemed to get rid of them though. Recently I bought another bag and noticed the same problem. So I baked my potting soil.
I couldn't detect the smell last night, but this morning I could. My husband complained about it all before work and then called me later and complained some more. I can't bring myself to actually tell him what caused it. All I would say was that it wasn't something we'd eat.
