Mulch covers and cools soils, reduces weed growth, and slows erosion. Mulches include bark chips, wood shavings, rock or gravel. Avoid using plastic in planting areas. Maintain your garden. Weeding, efficient watering, and pest control will keep your plants healthy and conserve water.
Fertilizers promote growth but increase water consumption.
Apply only the minimum amount of fertilizer needed, preferably during a period of natural rainfall.
