The City now offers rebates to encourage development of healthy soils. Why? Because healthy soils mean healthy plants. And healthy plants require less water and are better able to withstand stressors such as drought. The rebate applies to core aeration of lawn areas, top-dressing lawn areas with compost, using compost to supplement bed and garden soil, and using mulch on beds, gardens and around trees. Program is open to all City of San Marcos water utility customers, and allows for hiring contractors to do the work, or doing the work yourself.
