Thanks for all the feedback! I mulch and bag. Some stays on the lawn and some go into the bad. I have a "dead" bed I put lawn clippings at the end of the mowing season and now a layer of mulched leaves. I hope to put hosta and fern in that bed next year. I've also put the leaves around the base of a couple of small trees leaving space around the trunks. I live in a gardening town and my neighbors are watching! I did NOT put out 15-20 bags of leaves on the curb from a small to middling yard!
