I have heard and read that it is a good idea to cover perennials with
6 to 8 inches of leaves. We are in a new development and we do not have a lot of leaves; however, I obtained some awaiting pickup in the street of a nearby neighborhood and I raked up our few leaves. I placed them over three new this year plants and piled them up as much as I could. Then along came a wind and blew most away. I managed to save a few on one plant by running out and placing one large nursery plastic pot over the leaves with a brick on top to hold it there. My questions are will leaving the pot over the leaves covering the plant hurt the plant if I leave it there possibly all winter and what do most people do to keep the leaves piled up as high as 6 to 8 inches?- posted
