Mulching Leaves Into Lawn
I have only been doing a very little of this, but Scott's is now saying it's good to mulch all your leaves into the lawn, to the point that you see grass tips only. I know some have been doing that but I was surprised by Scott's endorsement. So, I guess I'll be trying it. I already know that mulching piles/rows of leaves in place in flower beds, around trees, etc. is great for whatever is growing there. In nature, topsoil accretes at the rate of 1" in 100 years. By mulching leaves, I have seen a tenfold increase in the formation of humus. Mulched leaves turn to rich, black soil almost before your eyes. I wasn't doing it on the lawn because I had always heard that the leaves were acidic and would stunt the growth of the lawn. Evidently that is not true. So, here's the link and you can check it out.
