Using Epsom Salt

• Epsom salt is made mostly of sulfur and magnesium. These minerals are vital to seed germination, production of chlorophyll and the conversion of sunlight into food.
  
  One of the only plants that doesn't do well with Epsom salt is sage. If you add Epsom to your garden, don't spray it on your sage plants or where it can affect them.
  
  Epsom salt won't stay in the ground, so you can't overdo it when it comes to using it as a fertilizer. While there are guidelines on how much to give individual plants, you don't need to worry about the exact amount of Epsom salt to use because using too much won't burn them the way using too much traditional fertilizer can.
  
  

Diluting in Water

• You can dilute Epsom salt in water to fertilize and feed your plants. For your lawn, use three pounds of Epsom salt for each 1250 square feet. Add several tablespoons of Epsom salt to warm water and dissolve it completely before adding it to your garden sprayer. Spray your yard generously and refill your sprayer as needed.
  
  While you're spraying your yard, spray other plants with the solution to give them a little boost. Using an Epsom salt spray on your roses keeps pests away. Feeding your plants Epsom salt has shown to increase flowering on roses and also causes the plants to grow bushier. It also helps pepper plants grow larger.
  
  Dilute two tablespoons of Epsom salt in water to feed your houseplants every month.
  
  

Dry Epsom Salt

• You can also use Epsom salt dry: Sprinkle it around the roots of the plants you want to feed. It gives your plants a great boost when you mix it into the soil before planting.
  
  You can use Epsom salt to fertilize trees, shrubs, roses, pepper and tomato plants in particular. It is a great alternative to synthetic fertilizers that will not only improve the health of your plants but your health, too, since you won't be exposing yourself and your family to as many chemicals.
