Using Epsom Salt on Plants: Ease Your Gardening Woes

Also known as magnesium-sulfate, Epsom salt plays a powerful role in your garden. It is good for plants like tomatoes and peppers and also works great for lawn care.

Read on to learn how to use Epsom salt for your plants and gardening endeavors.

Improves Seed Germination

Applying some to the soil before you begin planting your seeds in the spring will help get your garden off to a strong start.

The magnesium will help your seeds build stronger cell walls which will result in sturdier, more resilient seedlings, and plants.

Having it in the soil will also help your seeds. Later, their roots will absorb and retain more nutrients year-round.

Brightens Foliage

You can tell when a plant isn’t getting enough magnesium in its diet by the yellowed, withered look of the leaves.

Magnesium is needed for plants to produce chlorophyll. Chlorophyll is what gives your foliage a bright, healthy, green color.

When your plants are looking less than perky, give them some magnesium-sulfate to brighten them up.

The dosage is 1 tablespoon for every 12 inches of height of the plant. Do this once every month or so.

Prevents Transplant Shock

Another reason Epsom salt is good for plants is that it prevents root shock. It is always risky business moving seedlings from a container to the ground or repotting a grown plant.

Oftentimes the roots can become damaged. This is known as “transplant shock,” and the affected plant will never be the same.

You can combat the risks of transplant shock by using it to encourage nutrient absorption.

After transplanting, water the affected plants with a mixture of 1 tablespoon of Epsom salt and 1 gallon of water.

Deters Unwanted Visitors

Epsom salt works wonders for preventing many of the undesirable garden pests that might visit when not invited.

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 around the base of your plants. This remedy acts similarly to diatomaceous earth, irritating and scratching the feet and bodies of slimy creatures, bugs, and other critters.

Tastier Fruits

Fruit trees and berry bushes require a lot of water and nutrients. Applying it to the roots can help increase production and result in juicier, sweeter fruits.

Sprinkle a tablespoon around the base of each plant/tree about once per month to help improve your quantity and quality of fruit.

Juicier Tomatoes

Every gardener longs for the juiciest, plumpest, brightest red tomatoes on the block.

Epsom salt is good for your tomato plants because it will help them to produce plummy and juicy fruits.

Dissolve 2 tablespoons in one gallon of water and apply it around the base of the plant.

Repeat this every two weeks to maximize magnesium absorption and improve the taste and look of your tomatoes.

Strengthens Pepper Plants

Similar to tomatoes, peppers also put a heavy burden on their vines, which can expose them to additional health risks and nutrient deficiencies.

To strengthen the vines and improve fruit production, dissolve 2 tablespoons in a gallon of water and apply to the leaves via a spray bottle. You can also follow the instructions above for the tomato plants.

Besides, if you think your pepper plants might be getting too much water, you can apply Epsom salt in dried form.

Sprinkle 1 tablespoon per 12 inches of the plant around the base. Do this once every week.

Boosts Cucumbers

Though it provides cucumbers with a boost of energy that helps them produce more fruits, do not use Epsom salt as your only fertilizer.

Apply 2-3 tablespoons around the base of the roots every four weeks.

You can also apply it as a foliar spray by dissolving 2 tablespoons in a gallon of water.

Multiplies Blossoms on Rose Bushes

Do you ever look at your sad, wilted, blossom-less rose plant and wonder what you are doing wrong? The missing ingredient is likely magnesium.

It is believed by many that magnesium increases the number of blossoms that a rose plant yields, and will also spur the growth of new canes.

Again, magnesium also helps in the formation of chlorophyll, which will improve the color and texture of the leaves.

Adding some to the soil when first planting your rose bushes will result in gorgeous roses.

Repeat one more time each when there is new growth, and when the flowers are fully blooming.

Strengthens Grass Roots

Although some people might not consider their lawn to be part of their garden, it’s still something many of us want to keep healthy and green.

An easy way to do that is by using Epsom salt on your grass to keep the roots strong and the leaves green.

While it’s certainly not a complete fertilizer for grass, you can still use it to improve the look of your lawn.

By applying it with a spreader (about 2.5 pounds per 1000 square feet) or by diluting it in water and then applying it to the desired area.


As you can see, there are many uses for Epsom salts in the garden. It is a handy product and one that should be appreciated by all farmers.

Its wide range of benefits, from increased crop yield to pest control, puts it at the top of the list for natural, effective gardening remedies.

There are hardly any plants that don’t like Epsom salt. Therefore, start utilizing it today in the garden and you’ll see improvements in no time.
