Yeah, I agree theirs no way to "just mulch them in" up here in the north I've tried with no success.
I so wish you could try my set up. Maples, oaks, hickory, cherry, catalpa, tulip, magnolia, bald cypress all get reduced to minute particles. Locust leaflets do well too.....even the small little tiny leaves. done on a regular basis it really does work,,,,wet or dry.
