Quench is a unique, all natural starch-based product that will hold up to 400 times its weight in water to provide an "on demand" source of moisture for plants. This product releases its moisture much more readily than petroleum based products, making it unmatched in its ability to support the water needs of plants. Spread Quench on garden beds at the rate of 2 cups per 100 sq. ft. of garden. Rake or work into the top 3-4" of soil. Great for containers -- use 1/2 tsp. per quart of potting soil. Highly recommended in dry conditions!
