After the irrigation system is installed and the plants are in, it's time to spread the decomposed granite or crushed rock and any other mulches planned for your landscape.

If you have chosen to spread organic mulch around your plants, do this first. A layer one to three inches thick is sufficient. Inorganic mulch, such as decomposed granite, can go right on top of the organic mulch. Take care to keep all mulches two to four inches away from the base of the plants.

Tip: Start spreading mulch at the point farthest from the pile. This will help to avoid disturbing newly mulched areas. In addition, looking back on your work will give you a sense of accomplishment.
