SOIL MOIST" has been developed to assist the grower, nurseryman and interior and exterior gardener and landscaper in growing and maintaining vigorous plants. It is an effective water management aid designed to reduce the amount of plant waterings. SOIL MOIST" is an environmentally safe synthetic superabsorbant copolymer. The hydrophilic acrylic polymer particle size distribution has been selected to insure rapid initial uptake of water by a portion of the polymer followed by slower absorption of water by the balance of the polymer. Good initial soaking is required to insure that both the soil and the polymer absorb water to their maximum levels. . From the initial soaking, the polymer will soften and swell as water is absorbed. The polymer captures and stores water that would normally percolate through the soil. As the potting system dries the polymer will release its water reservoir. As an added benefit the continuous expansion and contraction of the polymer prevents the soil system from crusting hard. Though the polymer is soft, it prevents soil compacting. Rate: 2-3 oz. per 1" caliper tree or 1/2 oz. per 1 gallon size container.
