Like mulch, ground cover helps conserve water that seeps into the soil either from rain or from the nozzle of a garden hose. Ground cover slows evaporation to help hold moisture in the soil for all the plant life — both the ground cover plants and garden plants. The ground cover also blocks sunlight from drying out the soil underneath. Most herb ground covers need a deep watering once a week.
For best watering results, match water requirements for your herb ground cover plants with your garden plants. Ask an expert at your local True Value hardware store for watering advice.
Choose ground cover herbs that you know will do well in your particular climate.
Your herb ground cover’s foliage and root systems protect your garden from erosion, whether it’s from excess rain and runoff, wind, or hot and dryer-than-usual conditions. Ground cover leaves and roots help absorb excess water and hold it in the soil and make the soil healthier by promoting a good habitat for beneficial soil organisms. The foliage also shields soil from too much sun.
