I've been using the Schultz mix for a few years and i like it in spite of the fact that it has had a few weeds sprouting in it. Last week, i ran out and ended buying some Plants and Pots mix at the Co-op in town. I'd forgotten - but i found out quick - that it tends to get a lot of mold on it. Almost everything i planted in it has sprouted, but i don't like the idea of that mold. The other day i bought more Schultz in Dryden so i won't use the other stuff. Now the question is, can it just be mixed with potting soil for other things, or what should i do with it? Just dump it somewhere? Any ideas?
