About the cornmeal, in a nutshell
I'm not an inexperienced gardener but definitely not as experienced as y'all. About the cornmeal for fungus, in brief, if I sprinkle it around the base of my plants it will reduce fungal problems??? Last year I had a terrible time with fungus on everything--phlox, salvia, roses, etc... and I would occasionally spray with the Safer brand fungicide but I HATED to since it only comes mixed with insecticide. I don't like to kill little beasties--well not most of them anyway. I'm very in to growing host plants for caterpillars and obviously what kills one "bug" kills all bugs. So, back to the cornmeal, I like the idea of using it if you folks say it works.
