Mulch Adequately

Mulch retains moisture in the soil and moderates soil temperature while it adds nutrients, and reduces erosion and weeds.

Mulch can be purchased, by the bag or truckload; created by recycling "green waste" in the yard; and is even available for free from many cities and municipalities.

Although it is readilly available, most environmentally concerned sources will advise against the use of cypress mulch. Cypress are slow-growing, native-wetland trees that are being harvested for mulch faster than they can grow. Alternative mulches created from melaleuca, eucalyptus, and Australian pine are now available, as well as pine needles and fallen leaves from our own yards.

For best results, mulch should be spread 2--4 inches thick over the roots of trees, shrubs and plant beds. Keep the mulch several inches away from the plant stem or trunk to prevent rotting.

Do not mulch citrus trees.

Add new mulch as needed, usually once or twice a year. stirring the old mulch to promote air and moisture circulation to avoid matting.

Inorganic mulch such as gravel or colored rocks will not hold moisture and can even reflect heat, which is stressful to plants.

Create self-mulching areas under trees by allowing leaves to stay where they fall.
