THE FACTS

Epsom salt, also known as magnesium sulfate, is a naturally occurring compound that contains magnesium, sulfur and oxygen

There are MANY online recipes for using Epsom salt:

  • as a FERTILIZER
  • to treat PHYSIOLOGICAL PROBLEMS, such as blossom end rot
  • to PREVENT TRANSPLANT SHOCK
  • to DETER PESTS

NONE OF THESE RECIPES ARE BASED ON SCIENCE.
There are no scientific articles relevant to Epsom salt use in home gardens and landscapes and its use could create soil nutrient imbalances and cause injury to plants.

A SOIL TEST IS ABSOLUTELY REQUIRED BEFORE USING THIS CHEMICAL.
