Epsom Salt for Plants — Magnesium Sulfate for Gardens & Lawns

Epsom Salt for Plants is magnesium sulfate heptahydrate (MgSO4·7H2O): about 9.8% magnesium and 13% sulfur by weight. It dissolves completely in water for foliar sprays, soil applications, transplant drenches, lawns and nutrient solutions. Use it where magnesium is low: 1 tablespoon per gallon as a foliar spray every two weeks, 1 tablespoon per foot of plant height worked into the soil monthly, or 3 lb per 1,250 sq ft on lawns in spring and fall. Tomatoes, peppers, roses, potatoes, citrus and leafy greens respond most often. USP-grade raw material, sourced within the United States and repackaged without changes at our family-owned facility in Madera, California. Available in 1, 3, 5, 10, 20 and 25 lb bags, or two 25 lb bags. Backed by our 90-day satisfaction guarantee.
