Helpful Information

Lawn clippings, leaves and hay, for instance, all can be used as mulch. At a lawn center, you will find various types of commercially produced mulches, in bags that contain either 2 or 3 cubic feet of loose matter, such as cedar chips, cypress, or pine bark.

Tip: To ensure that weeds cannot grow in a flower bed, lay mulch 1 to 2 inches deep.
