Brandt Magnesium Sulfate with 9.8% magnesium and 12.9% sulfur. Commonly called Epsom salt, gardeners use it to improve crops.
Epsom salt is one of the most versatile household products, with uses ranging from creating an at-home spa treatment, soothing achy muscles, and improving garden-related issues. Epsom salt is not actually salt but a naturally occurring pure mineral compound of magnesium and sulfate. It's been used therapeutically for hundreds of years.
When gardening, most plants need nutrients like magnesium and sulfur to stay in good health and Epsom salt makes the primary nutrients in most plant foods (nitrogen, phosphorus, potassium) more effective. Sprinkle Epsom salt once weekly to help nourish your houseplants, flowers, and vegetables. Magnesium sulfate crystals, when added to the soil, provide vital nutrients that help prevent yellowing leaves and the loss of green color (magnesium is an essential element in the chlorophyll molecule) in plants. Add 2 tablespoons of Epsom salt to a gallon of water and sprinkle on your lawn to keep the grass healthy and green. Use Epson salts on your lawn and in your garden to safely and naturally get rid of plant pests.
