It’s possible to over-mulch leaves. If the leaf mulch is thick enough that it’s blocking and smothering the grass, that’s a problem. Ideally, you should still be able to see the grass when you’re done mulching to ensure its ability to continue growing. The solution is to make another pass at the top layer of leaf mulch to collect some of the top layer.

You can leave grass clippings on the lawn, depending on their length. You don’t want to completely cover new grass and block it from sunlight, or encourage moss crowd out the more delicate grass. However, short clippings are usually fine to leave on the lawn. In some cases, they can be beneficial: Clippings can be a source of fertilizer and help protect the ground as young grass blades develop.

Most junk removal services don’t take hazardous materials, including paint, gasoline, bleach, and other chemicals. When gathering quotes, ask the company about its specific restrictions.

Yes, you can conduct your own leaf removal, but consider that keeping up with leaf removal is time-consuming and requires regular yard work throughout the fall. The process can take a few hours a week. Professionals have lawn equipment that can speed up the process and save you time. Additionally, consider how you’ll dispose of the leaves. If your sanitation company won’t pick them up—especially if you have many bags from a once-annual cleanup— you’ll have to drive the bags to the dump. It’s usually easier to leave the work and disposal to a professional leaf removal service.
