Epsom salt is a chemical compound consisting of magnesium, sulfur, and oxygen. This was originally discovered in the town of Epsom in Surrey, England, thus the name. It’s been used in various ways including for body aches. But did you know that there are great Epsom salt uses in the garden?
Yes, you got that right. You can use Epsom salts for garden plants and help them grow beautifully. Here are 10 ways for how you can do it.

Epsom salt uses in the garden for healthier plants on pots
Keeping plants in pots healthy is a lot harder than it looks because they go magnesium-deficient faster.
To sort this out, you just have to add 2 tablespoons (or 30 ml) of Epsom salt around the plant. Note: Just do this once a month.
Increase nutrient absorption
Most commercial fertilizers are packed with magnesium, but why bother buying if you can get that from Epsom salt?
When you simply put Epsom salt on the soil around your beloved plants, they will absorb other nutrients that are present on the soil more efficiently.
Shoos garden pests away
We all know garden pests, they’re the number 1 enemy of gardeners and plant growers. While you are doing everything to the best of your ability, here they come munching away your greeneries.
Thankfully, Epsom salt is there to save the day. It does irritate pests, but you may need to sprinkle it more often onto your plants since it is water-soluble.
Great for nightshade plants
You can use Epsom salt for tomatoes and other nightshade plants that need a lot of magnesium.
Luckily, it’s one of the main components of Epsom salt. You can either sprinkle it at the base or mix it with water and then pour it in.
For best results, it’s highly recommended to keep adding Epsom salt to them every two weeks.
Exterminates weeds

Epsom salt is a great ingredient in getting rid of those unwanted greeneries. Create your own Epsom salt weed killer by mixing it with vinegar and some dishwashing liquid.

Keeps leaves greener than ever
Plants’ leaves will start to turn yellow when they do not get enough magnesium. Thankfully, Epsom salt is rich in that.
