Epsom Salt Garden Hacks

Always do a soil test first to be sure the Epsom salt isn’t going to have any sort of adverse effect.

Sweeter, Larger Tomatoes

You may already know that tomatoes need magnesium to grow big and strong. To make sure they get enough, Epsom salt to the rescue!

When you’re planting, put 1 tablespoon of the salt in the bottom of the hole and put a thin layer of dirt over it. Drop the seedling in the hole.

Mix 1 TBSP Epsom salt in a gallon of warm water. Every two weeks, water the plants with this mixture.

Delicious Peppers

Just like tomatoes, all sorts of peppers respond beautifully to the same treatment. They’ll grow bigger and more flavorful.

More Colorful Roses

Soak the roots of new rose bushes in Epsom salt and water. Sprinkle the roots of each rose bush with Epsom salt once a month.

Stunning Azaleas

Every two weeks, mix  1 TBSP in a gallon of warm water and spray the ground beneath the flowers.

Sweeter Apples

Dissolve Epsom salt in water and put it around the base of the tree. Works on other fruit trees and bushes as well.

Yellow Leaves on Plants

Sprinkle Epsom salt around the base of the plant. It’s amazing how well it works!

Leaf Curling

When leaves of a plant begin to curl, it may be a magnesium deficiency. 1 TBSP per gallon of water is the perfect solution to soak the soil.


Use the standard 1 TBSP per gallon of water mixture to feed your ferns to get beautiful, healthy green leaves.

Beautiful Lawn

Put Epsom salt in a seed spreader and distribute it on the lawn. For every 1200 square feet, use about 3 pounds of salt.

Get Rid of Pests

Snails (and other creepy crawlies) really hate the way salt feels. Sprinkle it over your garden to keep them out.

Weed Killer

Mix 2 cups of the salt in one gallon of plain, white vinegar. Add some dishwashing liquid. Shake it up and spray directly on weeds. Be careful though. It will kill other plants it gets to, so be mindful as to where you use it.

Help to Remove Tree Stumps

Drill lots of holes in the stump, about 3 inches apart. Pour salt directly in the holes and fill with water. Repeat as often as needed to make the stump begin to dry out and become more brittle. It’ll make it easier to get the stump out.

Those are all the Epsom salt garden hacks I have for you today.

Are you a talented gardener with a green thumb? What hacks do you have for me? I’d be so, so grateful if you’d share!

  1. You start your article by warning readers to do a soil test for any “adverse effects.”   Can you suggest how to do that?   The only test I can think of is to try your methods and see if they kill my plants or not.    Or I guess I could have a duplicate garden with the same plants and same conditions and do a comparison, but this seems rather unwieldy.   Suggestions? 

  2. New soil will need to be built up with compost. To kill off grass or weeds that are coming up is to get hot compost and spread it on the tilled soil. cover it with black plastic for a few weeks. This should cook the soil and deprive the weeds of sunlight. (each week add some water to keep it moist but not soggy.) When you get ready to plant you can keep the plastic on and transplant seedlings by cutting into the plastic and planting in a weed free bed. If you are growing tomatoes you should use red plastic to improve the productivity of the plant. The ancient method of planting symbiotic plants together Called the Three sisters (Corn, Beans and Squash) this helps build the soil nutrients and balances the soil. Marigolds are a good pest prevention plant Also in your yard plant a section of flowering plants to attract pollenating critters. There are several natural gardening resources available on line ( I like Mother Earth News among others)
