As the temperature slowly begins to rise, it will be important to feed your lawn, but you do not need to use a harsh chemical fertiliser to get healthy grass. Many chemical fertilisers harm animals and can kill beneficial microbes in the soil, reducing lawn fertility over time. 

Instead, the gardening experts at SubLawn have shared that a simple way to get thicker and greener grass is to use Epsom salt. They said: “Applying Epsom Salt to your lawn is a safe, natural solution to help with seed germination, nutrient absorption, growth, and the general health of lawns and plants in your yard. It contains magnesium, which helps with the above-stated.”

Epsom salt is a mineral often bought as a natural bath soak. It contains lots of magnesium, which helps plant energy production and makes the grass turn green.

If your grass begins to look patchy and yellow after the winter, Epsom salt can help give the lawn a boost so it is more likely to grow healthily and strong in spring.

What is also fantastic about Epsom salt is that it helps balance the pH level of soil, making lawns less acidic, which can stop moss and mould from growing on grass. 

How to use Epsom salt on a lawn 

All you need to do is place the Epsom salt in the water and mix it until it dissolves. Watering the lawn with fertiliser is better so the grassroots can easily absorb the nutrients. 

The expert said: “Use about a half pound of Epsom salt for every 100 square feet of lawn. 

“It’s important that you do this during the [autumn] or spring months because if you fertilise your lawn in the summer, this will contribute to weed growth, which you will have to deal with later, and obviously, the winter time is difficult to do much with your lawn.”

Lawns need to be fertilised once the grass begins growing again in mid-spring, typically in late March to early April. 

It is important not to feed your lawn early, as this wastes nutrients and does not allow grass roots to grow properly. This can make your lawn less drought-tolerant once summer arrives. 

You will know it is time to feed your lawn once the grass actively begins growing again and you have been able to mow it once or twice. 

The simple way to know if your grass can be fertilised is by checking the soil temperature with a thermometer. Simply stick it in the ground and if it is consistently over 10C then you can feed it. 

If you fertilise your lawn with Epsom salt every four to six weeks during its growing season, then it should help the grass turn a vivid green colour throughout the rest of spring and summer.
