Avoid using Bermudagrass as a mulch because sprigs and seed from common bermuda may sprout, causing a weed problem. Clippings can also be returned directly to the lawn using a mulching mower. Mulching mowers will not only cut the grass, but will also shred the grass into smaller pieces. These clippings used as mulch will filter down through the grass canopy, conserving moisture as well as returning nutrients to the lawn. Mulching will not increase thatch accumulation.
Leaves make excellent mulches for both gardens and flowerbeds.
Run leaves through a mulching or rotary mower to increase their surface areas and keep them from matting. Shredding leaves in this way will increase breakdown and return nutrients to the soil faster. Brush debris from pruning shrubs and trees in winter and spring is somewhat more difficult to handle than grass clippings or leaves. A power chipper or shredder is needed to chip or shred branches into a mulch, which makes an excellent mulch around trees and shrubs. Avoid sawdust that has turned sour from fermentation in deep piles.
