Maintain a two to four inch layer of mulch on the soil surface to reduce weeds, infiltrate rain water, and reduce compaction.
Develop healthy soil for plants that are vigorous and naturally pest-resistant.
Apply as little fertilizer as possible.
If you use fertilizer make sure it stays on the landscape, and carefully water it in so there is NO runoff.
