The Sustainable Landscapes Program promotes living soils with a balanced composition of microorganisms and inorganic elements. Plants thrive in living soils, which hold on to rainwater when it is available. Read on below for information on how to obtain compost and mulch to help enhance your landscape.

Compost: Good compost brings oxygen, water and life in one package. When compost looks like soil, it can be worked directly into the soil. As it decomposes in the soil, it encourages the formation of macro-aggregates, which bind existing soil particles and decomposed organic matter. This combination creates a more stable and better functioning soil structure.

Mulch: The SLP promotes the use of organic mulch to cover the soil. Mulch Shredded bark mulch | Flickr - Photo Sharing!always stays on top of the soil, and is never worked in. It often looks like the recycled debris that it is. The microbes in healthy, biologically diverse mulch “knit” the organic matter together, forming a thick blanket. This cover protects the soil and plant roots from temperature change, keeps moisture in by slowing evaporation and keeps weeds from sprouting by reducing sunlight penetration.
