There are many reasons to use Epsom salt in your garden. It gives seeds a better start and helps keep away certain pests.
Epsom salt also helps vegetables such as tomatoes and peppers grow and produce larger yields. Plus, it also benefits roses, jasmine, hydrangeas, ferns, and your lawn.
Read on to learn how to use Epsom salt for your plants.
1. Improve Seed Germination
The magnesium will help your seeds build stronger cell walls which will result in sturdier, more resilient seedlings. Moreover, having Epsom salt in the soil will also help plants establish more quickly.
Dissolve one tablespoon of Epsom salt in a gallon of water. Apply as a drench to the soil before you begin planting seeds.
2. Brighten Up Foliage
You can tell when a plant isn’t getting enough magnesium by the yellowing of the leaves. There may also be early leaf fall.
Magnesium is needed for plants to produce chlorophyll. Chlorophyll is what gives leaves their bright, healthy, green color.
When your plants are looking less than perky, give them some Epsom salt to brighten them up.
So, how much to use? The dosage is 1 teaspoon for every foot (12 inches) of plant height. Water well. Do this once every month.
3. Prevent Transplant Shock
It is always risky moving seedlings from a container to the ground or repotting a grown plant.
Oftentimes a plant goes through various stresses when transplanted. This is known as transplant shock . As a result, if not taken care of, the affected plant may never be the same.
Use Epsom salt to combat the risks of transplant shock and encourage nutrient absorption. After transplanting, water the affected plants with a mixture of one tablespoon of Epsom salt and a gallon of water.
4. Keep Away Pests
Epsom salt works wonders for preventing many of the undesirable garden pests that might visit.
Although it won’t kill snails and slugs as table salt does, it will irritate them enough to keep them away from your plants.
Sprinkle some around the base of your outdoor and indoor plants. This remedy acts similarly to diatomaceous earth, irritating and scratching the soft bodies of slimy creatures.
5. Increase Production of Fruit Trees
Fruit trees and berry bushes need a lot of water and nutrients. Applying Epsom salt to the roots can help increase production and result in juicier, sweeter fruits.
Dissolve a tablespoon of Epsom salt in a gallon of water. Next, pour the solution around the base of each tree once per month.
6. Sweeter Tomatoes
Every gardener yearns for juicy, heavy tomatoes. Epsom salt is good for your tomato plants because it will help make the fruits taste sweeter.
To use Epsom salt for tomato plants, the dosage is 2 tablespoons to a gallon of water. Let it dissolve before applying around the base of your plants.
Repeat this every two weeks.
7. Strengthen Pepper Plants
Like tomatoes, peppers also put a heavy burden on their vines. This can make them prone to magnesium deficiency. Thus, Epsom salt will help pepper plants produce bigger, tastier yields.
To use Epsom salt on pepper plants, dissolve 2 tablespoons of Epsom salt in a gallon of water. Shake well and spray on the leaves of the plants.
But, if you think your plants might be getting too much water, you can apply Epsom salt in dried form. Sprinkle around the base of plants as outlined in point two of this article. Do this once every week.
8. Boost Cucumbers
Though Epsom salt provides cucumbers with a boost of energy that helps them produce more fruits, do not use it as your only fertilizer.
To use Epsom salt for cucumbers, apply 2 tablespoons around the roots every four weeks and water well. You can also apply it as a foliar spray by dissolving 2 tablespoons in a gallon of water.
9. Healthier Rose Bushes
Are your roses looking dull, lacking radiant, abundant blooms? The missing ingredient is likely magnesium.
It is believed by many that magnesium increases the number of blossoms that a rose plant yields. Magnesium also helps increase the production of chlorophyll in these plants.
Adding some Epsom salt to the soil when first planting your rose bushes will result in gorgeous roses. You can also apply to existing rose bushes by sprinkling half a cup of Epsom salts around the base of the plants and water well.
It’s best to do this before the plants bloom in the spring.
10. Keep Your Lawn Green
Although some people do not consider their lawn to be part of their garden, it’s still something many of us want to keep healthy and green.
Use Epsom salt on your lawn to enhance nutrient absorption and growth. While it’s not a complete fertilizer for grass, you can still use it to improve the look of your lawn.
Apply it with a spreader (about 2.5 pounds per 1000 square feet). Alternatively, dilute it in water and spray the desired area.
Epsom salt also serves as a pest deterrent, keeping away raccoons, slugs, and other pests from your lawn.
11. Homemade Weed Killer
Does Epsom salt kill weeds? It will — if combined with other ingredients such as vinegar, but straight Epsom salt will not kill weeds.
Make a vinegar Epsom salt weed killer by mixing together half a cup of liquid soap, 2 cups Epsom salt, and one gallon of household white vinegar. Dawn dish soap is fine, but we use organic liquid soap in our recipes.
This 3-ingredient homemade weed killer will save you a ton on store-bought products to eliminate weeds or the need to pay someone to do it manually.

You can use Epsom salt on nearly all garden plants. But, the ones that benefit the most are those highlighted above.
Nonetheless, Epsom salt is mostly used on tomatoes, peppers, and roses. However, do not use it as a substitute for fertilizer as its N-P-K value is 0-0-0.
