In a large bucket or watering can, mix 2 tablespoons of Epsom salt with 2 gallons of water.
Add a few drops of mild dishwashing liquid (make sure it doesn’t contain any harsh chemicals that could damage your lawn).
Spot treat brown spots:
Pour the mixture directly onto the brown spots. Make sure the area is thoroughly soaked but not waterlogged.
Water regularly:
Water the treated area lightly but regularly over the next few days. The Epsom salt will help revitalize the grass by providing essential nutrients, while the dishwashing liquid will ensure even distribution.
Monitor and repeat as needed:
After a week or two, you should see the brown spots begin to green up. If the spots are stubborn, reapply the mixture after two weeks

Why It Works So Well
Epsom salt is a gentle, natural way to improve the health of your lawn. The magnesium in Epsom salt helps your grass absorb essential nutrients, such as nitrogen and phosphorus, that are essential for growth and greenery. Unlike harsh chemical fertilizers, Epsom salt won’t burn your grass or harm the environment. The dishwashing liquid acts as a wetting agent, ensuring that the solution penetrates deep into the soil where it can do the most good.
This method is incredibly effective because it gets to the root cause of brown spots without loading your lawn with chemicals or requiring a lot of work. It’s a quick and easy fix that works gradually to restore the health and beauty of your lawn.
