That's right. The heat (either from composting, or another
source) kills any viable "weed" seed in what ever soil is
processed as potting soil. If the soil actually contained a
substance that _inhibitted_ weeds, you couldn't grow any
ornamentals in it either... after all, a "weed" is just a plant
growing somewhere that you don't want it!<g>
