No; the mulch suppresses seed germination. I believe it's nitrogen that is tied up by the decomposition process. I did an experiment one time, put a bunch of not quite compost & wood chips on one side of a bed, not the other, then seeded both sides with quick growing greens & radishes & such. I was so expecting the plants on the side of the compost to be absolutely bursting. Instead, absolutely nothing. The seeds on the other side were ok, the ones that were a foot or so away from the mulch.Can I simply broadcast seed onto a mulch layer and expect good results?
