Epsom Salt for Plants: Ease Your Gardening Woes

Magnesium sulfate is well-regarded as an excellent remedy for sore, achy muscles. It also makes an excellent skin scrub and aid for stomach issues, among other things.

But did you know that it can also play a powerful role outside of your house and on your farm?

Be sure to buy a brand that is approved for organic use. Read on to learn about how using Epsom salt on your plants can ease your gardening woes.

Improves Seed Germination

Applying some Epsom salt 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 some magnesium in the soil will also help your seeds, and later their roots, absorb and retain more nutrients year-round.

Brightens up Your Foliage

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

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

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

All that is needed is about 1 tablespoon for every 12 inches of height of the plant. Do this once every month or so.

Prevents Transplant Shock

It is always risky business moving seedlings from a container to the ground or re-potting 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 Epsom salt to encourage nutrient absorption.

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

Deters Unwanted Visitors

Magnesium sulfate 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 Epsom salt 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.

Epsom Salt and Tomatoes

Every tomato grower longs for the juiciest, plumpest, brightest red tomatoes on the block. As a result, many have been asking how to use Epsom salt for tomatoes.

Adding some to your tomato plant’s diet will help it to produce plummy and juicy tomatoes.

Because tomatoes cause so much strain on their vines, this weight often results in an accelerated loss of magnesium in the plants.

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

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

Epsom Salt for Peppers

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 plants and improve fruit production, apply Epsom salt dissolved in water to the leaves via a spray bottle. You can also follow the instructions above for the tomato plants.

If you think your pepper plants might be getting too much water, you can also apply it in dry form. Sprinkle 1 tablespoon per 12 inches of plant around the base; do this once every week.

Epsom Salt for Cucumbers

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

Apply 2-3 tablespoons around the base of the roots every four weeks. It can also be applied as a foliar spray by dissolving 2 tablespoons in a gallon of water.

Epsom Salt for 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, this salt also helps in the creation of chlorophyll, which will improve the color and texture of the leaves as well.

Add 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.

Epsom Salt on Grass

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 it on grass (or your lawn) to keep the roots strong and the leaves green.

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

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

Which Plants Don’t Like Epsom Salt?

Plants that require a lot of magnesium such as tomatoes, peppers, and roses like magnesium sulfate.

However, you’ll want to avoid using it on plants like beans, lettuce, peas, and spinach that can thrive in soils with low levels of magnesium.


Epsom salt is a handy product and one that should be appreciated by all gardeners.

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

Start utilizing magnesium sulfate today in your garden and you’ll see improvements in no time.
