Is epson salts good for your lawn?

No, Epsom salt is not generally recommended for use on lawns. While Epsom salt (magnesium sulfate) is an essential micronutrient for plants, it is typically applied to plants directly rather than to the soil. Epsom salt can be beneficial for plants in small doses, as it helps to improve nutrient absorption and can alleviate magnesium deficiency. However, applying too much Epsom salt can actually be harmful to plants, causing nutrient imbalances and even burning the roots.

For lawns, it is generally better to use a balanced fertilizer that contains all the essential nutrients that grass needs, rather than relying solely on Epsom salt. If you suspect that your lawn is deficient in magnesium, it is best to have a soil test done to confirm this before applying any fertilizer or amendments.
