Treatment
Broad Area Treatment
Flower Beds, Ornamental Gardens
Two methods available: sprinkle a small amount (1/2 tsp.) of Soil Moist Plus 7-7-7 in the plant hole, plant and cover with soil or apply one and one half pounds per 100 square feet of ground area. Spread the polymer and work into the soil at a depth of three to four inches.
Turf/Sodding
Apply at a rate of nine pounds per 1000 square feet or 400 pounds per acre if worked into the soil at five to six inches. Use six to eight pounds per 1000 square feet (260 to 350 pounds per acre) if worked into the soil at three to four inches. Broadcast the polymer with a spreader or drop seeder for even disbursement. Work into the soil, spread seed or lay sod, roll and soak thoroughly. If applying grass seed, you may want to use our Soil Moist Seed Coat.
