Epsom Salts in Gardening

Used as a fertilizer, Epsom salts help absorb phosphorous and nitrogen. Sulfur, a key element in plant growth, is critical to production of vitamins, amino acids (therefore protein), and enzymes. Epsom salts contain all of this.

Epsom salt is also a source of calcium and will help restore the calcium in your plants and soil. Epsom salts can be used in place of Cal-mag and is much less expensive. Epsom salt helps improve flower blooming and enhances a plant’s green color. In addition, it can even help plants grow healthier & bushier.

Just substitute it for regular watering either once or twice a month. however, it’s a good idea to test your soil to determine whether it’s deficient of magnesium. Diluted with water, Epsom salt is easily taken up by plants, especially when applied as a foliar spray. The dilution rate for spraying is 2 tablespoons (30 mL) of Epsom salt per gallon of water once a month. For more frequent watering, every other week, cut this back to 1 tablespoon (15 mL).

The dilution rate for root watering is 1 TBS per gallon of water. High levels of phosphorus in the soil prevents plants from absorbing magnesium even though there might be lots in the soil.

Magnesium boosts seed germination by strengthening cell walls and providing increased energy for growth. Epsom salts can be applied to the roots of newly repotted plants until saturated.  Epsom salts will help your lawn achieve maximum growth and lushness.
