For gardeners with busy schedules, the GardenMat Rectangular Garden Bed Hydration Mat ensures that your plants stay healthy without the time-consuming maintenance. This hydration mat absorbs over 200 times its weight in water to then slowly release it into the soil below. You don't have to worry about refilling it either - it absorbs precipitation through its permeable surface. As an added bonus, the mat also provides weed control and harsh weather protection. Simply soak it in water overnight before installing.
