Epsom salt (hydrated magnesium sulfate) is known for its home remedy uses, but the garden might be the place that it shines the most. Like store-bought fertilizers, Epsom salt contains magnesium, which aids in seed germination, chlorophyll production and absorption of vital nutrients like nitrogen and phosphorus.
Most plants grow better with a ratio of two teaspoons to one gallon of water per month. You can also dilute the Epsom salt with water in a bottle and apply as a foliar spray. Misting the plant greatly increases its growth. This works especially well on vegetables and roses. — Taylor Peterson
