Soil Moist stores over 200 times its weight in water, then slowly releases it to plants as needed. Reduces frequency of watering by 50% and works effectively for up to 5 years. Not only do you water less often, you lose less moisture to run-off and evaporation. Safe to use on all plants. A must for container gardening and beds prone to drying out. Helps establish new plants by reducing shock of transplanting.
