Yes, Epsom salt (magnesium sulfate) effectively helps plants with magnesium deficiency, providing essential magnesium and sulfur for chlorophyll production, leading to greener leaves, stronger growth, and better fruit/flower development, especially for crops like tomatoes, peppers, and roses, but should be used cautiously to avoid calcium imbalance.
As a drench, prevent toxicity by using the mixture only if a soil test indicates a deficiency of magnesium. When diluted with water, Epsom salt is most easily taken up by plants when applied as a foliar spray. Most plants can be misted with a solution of 2 tablespoons of Epsom salt per gallon of water once a month.
You can apply Epsom salts through the drip system at the rate of 60 ppm or dissolve 1 to 2 pounds in 100 gallons of water and apply as a drench. Do not mix Epsom salts with another water-soluble fertilizer. When applying as a side dressing, apply 1 tablespoon (about ½ of a dry ounce) per plant.
