Unique root zone moisture manager that effectively reduces the overall watering requirements of lawns, shrubs, trees, flowers, fruits and vegetables by as much as 50% or even more. Hydretain is not a wetting agent or a polymer gel. It is a blend of hygroscopic and humectant compounds that convert moisture vapor in the soil into water droplets that plants can use. This process improves water and nutrient uptake to help plants thrive, even under heat and drought stress. Hydretain Granular is on an organic compost carrier, which can be spread, broadcast or topdressed. 3 lb. bag covers up to 1,000 sq. ft. of lawn and 300 sq. ft. of garden. Perfect for potted plants, hanging baskets, and flower and veggie gardens. Kid and pet friendly, and easy to apply.
