Should you use Epsom Salts in House plants? |How to use, Pest control, Magnesium Deficiency

Updated: Sep 13


Epsom salt is a chemical compound that is made of sulphur, magnesium and oxygen. It's also known as magnesium sulphate. Find out why using it in your house plants can be highly beneficial for your plants.





Why does using Epsom Salt benefit plants?


Epsom salt increases the magnesium and sulphur count in the soil.


You might ask how an increase in magnesium and sulphur helps your plants? The reason for this is because plants use the process of photosynthesis to produce their food.


That process requires chlorophyll, which absorbs light to provide energy for photosynthesis.


You might ask, how does magnesium relate to this? Magnesium happens to be the central component in making chlorophyll.



How to preventing magnesium deficiency with Epsom Salt


So, to put it simply, adding Epsom salt to your house plants' soil helps your plants make their food, especially if your plants show signs of magnesium deficiency.


The usual sign of magnesium deficiency in house plants is chlorosis. Chlorosis is a discolouration seen in the leaf veins. See below





A splotchy yellowing is caused between the veins of the plant's leaves when the plant does not get adequate amounts of magnesium.


Using Epsom salt not only helps your plants to make their food, but it also helps to bring back the vibrance in their appearance since more magnesium will ensure that plants do not suffer from chlorosis.






Using Epsom Salt as Pest control


Salts are also used to dehydrate and kill pests such as snails and slugs. Using Epsom salt instead of normal table salt helps provide more nutrients to your plants while also getting rid of the pesky pests without much trouble.



How to use Epsom Salts


Here is a list of a few ways to use Epsom salt in your house plants:


  • Add in one tablespoon of Epsom salt for each gallon of water and water your plants as normal.

  • Or you could spray the area you intend to plant before planting the seed.

  • If you would like to use the salt for pest control, add 1tsp to 1 cup of water. Then, spray the solution all over the plant.

  • To use Epsom salt to restore the vibrancy of your plants, mix one tablespoon of the salt with four cups of water. This solution is for one foot of the height of the plant. So tweak it according to the height of your plant and simply spray the solution all over the plant.

So, if you are an avid grower of house plants, you should find the use of Epsom salts very beneficial.
