We have all heard of Epsom Salts and most likely already have it in our homes. But did you know that there are amazing benefits for using this humble mineral in the garden?

Epsom Salt is a mineral compound of magnesium and sulfate and is made from a rock substance called Dolomite.

Here are some benefits of using Epsom Salt in the garden:

  1. Stimulates plant growth
  2. Improves photosynthesis
  3. Increases nutrient uptake
  4. Increases flavour of fruits and veg
  5. Increases yield
  6. Prevents leaf curling (sign of possible magnesium deficiency)
  7. Prevents Yellowing leaves (sign of possible magnesium or sulphur deficiency)
  8. Deters slugs and snails (when sprinkled on their path)

Pretty amazing, right? We think so too! So let’s take a look at some basic methods and rates for how to apply Epsom salt to plants and soil. NOTE: It is always advisable to have a soil test done before applying any nutrients to soil.

Planting Seedlings & New Plants

  • Place 1 tablespoon of Epsom salt in the bottom of the hole you have prepared for your plants. Cover with a thin layer of soil and gently place your plant in the hold and loosely cover with soil.
  • Before planting or transplanting, soak root balls in a solution of 1/2 cup Espom salt to 3L warm water that has been cooled. This will give the roots an added boost and prevent shock.

Top Dressing

During the growing season, sprinkle about 1 tablespoon directly around the base of the plant and water in well.


Mix 2 tablespoons of Epsom Salt in 3L of warm water and let cool. Pour at the bast of plants and allow the solution to soak into the ground. This will improve the overall health of your plants due to the added magnesium boost.
