Epsom Salt (Magnesium Sulfate) and Its Benefits for Plants Epsom salt is a chemical compound known as magnesium sulfate. It contains two essential nutrients for plants: magnesium and sulfur. Magnesium: Plays an important role in seed germination, strengthens plant cells, promotes the production of chlorophyll (a green pigment necessary for photosynthesis), increases the absorption of nitrogen and phosphorus, and helps with healthy flower and fruit growth. Sulfur: Also necessary for the production of chlorophyll and the absorption of nutrients. Therefore, Epsom salt (magnesium sulfate) can help plants become greener, promote better flowering, and increase overall plant growth. In addition, Epsom salt can help repel snails and certain pests (such as rodents) that are often found near agricultural water sources.
