How to use epsom salt for fertilizing lawns

Updated April 17, 2017

Epsom salt is a good source of magnesium and sulphate to help turn the lawn green. It can aid the lawn's ability absorb phosphates and nitrogen, two important nutrients for a healthy and happy lawn. It can also help with new grass germination and keep pests away from your lawn. You can purchase Epsom salts at many grocery stores, pharmacies or health stores.

Mix Epsom salts with your typical lawn fertiliser. You want a ratio of 0.227kg. of Epsom salts for every 1,000 square feet of lawn.

Distribute the mixture evenly on the lawn with a fertiliser spreader in the early spring.

Water your lawn thoroughly so the fertiliser and Epsom salts do not burn the lawn. Watering will also help the mixture get deep into the roots of your lawn.

Fertilise again with the same ratio in the fall.

Tip

You can also mix the Epsom salts with water and spray on our lawn. An ounce of Epsom salts per gallon of water is sufficient. Add fertiliser in the early morning or evening when the temperatures are cooler.
