the secret ingredient to plant care: epsom salt

If you're looking for a quick and inexpensive way to fertilize your plants, you'd probably be surprised to know it's already under your bathroom sink. This is hailed as ‘the best-kept gardening secret’ by some, though it's been used in gardening for hundreds of years. Introducing your plant's new best friend...

Epsom Salt

Epsom salt is magnesium sulfate. It's a great way to help your plants absorb nutrition better. Epsom salt helps improve flower blooming and enhances a plant's green colour. It can even help plants grow bushier. Epsom salt is made up of hydrated magnesium sulphate (magnesium and sulfur), which is important to healthy plant growth.

Epsom Salt for Plant Care

Epsom salt helps to...

  • Improve Nutrient Uptake: Epsom salt contains magnesium, which is an essential nutrient that helps a plant perform some of its essential functions. One of these is that magnesium increases a plant’s ability to absorb other nutrients, such as nitrogen and phosphorus, without which it would struggle to thrive.
  • Make Plants Greener: Magnesium, one of the main elements of Epsom salt, is said to make plants greener. It does this because magnesium is useful in the plants’ creation of chlorophyll, which is what determines a plant’s leaf colour.
  • Provide Micronutrients: Epsom salts contain two micronutrients which are useful for the plant, and these are magnesium and sulfur. The needed micronutrients may differ from plant to plant. 

How to Use Epsom Salt

Take a teaspoon of epsom salt and mix it directly into the soil. Top with fresh water.


Take another teaspoon of epsom salt mixed with water and lightly spray it on the plant, especially to aid with flower or fruit production. 

It's as easy as that!
