You don’t need to rake all of those pretty leaves. There are a few reasons not to. The leaves provide shelter and even food for animals like chipmunks, box turtles, and earthworms. Butterfly pupae use the layers for protection as they grow over the chilly months.
As the leaves decompose (no, they won’t litter your lawn forever), they form a natural mulch and help fertilize the soil. They can be mulched with the lawnmower next spring.
Leaves do not belong in the trash. If you must rake take them to one of them to a compost site. Personally, I like to photograph them. Have you ever photographed a leaf using a macro lens?
