Peat moss is widely available and is one of the primary sources of organic material that homeowners use for soil problems in lawns and gardens. Organic matter in the soil becomes depleted and needs to be replenished, according to New Mexico State University horticulturalists.
Peat moss usually comes in two forms: moist or dry. When buying peat moss by the pound, buying the dry form is the most economical because you are paying for the weight of the water in the moist form. However, if you plan to use the peat moss immediately, you might be better off with the moist form because it is ready to use immediately. You must soak the dry peat moss in water before using it or it might blow away when you mix it with soil, or repel water after you finish mixing.
Most plant nurseries sell peat moss in bales or plastic bags. Check the business section of your telephone directory for plant nurseries in your area, or contact your county extension service or find one through the Internet.
Most retail stores with lawn and garden departments sell peat moss in plastic bags, including national chain big-box stores and hardware stores, as well as smaller retail stores with lawn and garden departments. Examples of national chain retail stores with lawn and garden departments include Home Depot, Lowes, Wal-Mart, K-Mart, Ace Hardware and True Value.
