Epsom salt has a variety of uses, but did you know it can help you in your garden? First found in England, Epsom salt is built of the mineral hydrated magnesium sulphate. This mineral is extremely valuable to gardeners, and this article is going to tell you exactly how you can make it work for you.

These are some of the ways that Epsom salt can help you.

Epsom salt can…

Assist produce in enhanced nutrient absorption

Adding Epsom salt to soil before planting can increase your plant’s ability to absorb nutrients, quite naturally. There’s no expensive additive or fertilizer necessary, no chemicals to make your food toxic, an ability to keep an organic growing garden.

Benefit your rose bushes

One of the plants that Epsom salt is best for is roses. Interestingly, it seems to increase the number of blossoms, and produce healthier blossoms overall on the lovely plant that so many enjoy. This is related to the magnesium that Epsom salt offers, a mineral that seems to be at the root of Epsom salt’s gardening benefits.

Seasoned gardeners recommend that roses be fed Epsom salt once while planting, once when initial growth is apparent, and again when they are blooming. This should be enough to continually prosper the plant.

Get you a bigger harvest of Capsicum

Epsom salt can be a great source of nutrients and health for a variety of plants, but in particular it has been known to help capsicum. When just one tablespoon (per 30 cm of plant height) of Epsom salt is fed to Capsicum plants bi-weekly, you’ll see a significant increase in your capsicum harvest.

Improve the coloring of the plants

Ever had a plant with yellowed leaves? Doesn’t it just make you feel like the plant is dying and there isn’t anything you can do about it? Try a monthly dose of Epsom salt, adding a single tablespoon for every 30cm of height should do, and see if that doesn’t just perk the plant right back up. This increases the healthy green color of the foliage.

Increase the chance of transplanted plant survival

When plants get transported, they are at greater risk of failing. Epsom salt helps to increase the chance of survival when plants are moved from one house to another. To take advantage of this, add some salt to the roots, then a layer of soil on top of the salt, and see if that doesn’t just help your plants survive!

Offer more efficient seed germination

Epsom salt can be used as a soil enhancer to ensure that it will more effectively germinate the seeds that are planted. Germinated seeds are stronger, they grow better, and they lead to a healthier garden. So how do you put Epsom to work in this way? Add between 1 and 2 tablespoons to the bottom of a hole before you plant in it.

Pester pests

You read that right. Just by surrounding your plants with a little bit of Epsom salt, you can significantly reduce the number of pests coming into your garden. This is because Epsom salt crystals can irritate unwanted pest’s bodies. It is worth noting however, that it’s not a permanent effect. Just like any other kind of salt, Epsom salts do dissolve with water (and rain just so happens to be made of the stuff), meaning you may need to reapply this fix for longer success.

Provide a better tasting tomato plant

Tomatoes are one of the most popular plants for a garden, and Epsom salts can help them taste even better. This is because tomatoes tend to suffer from a deficiency in their levels of magnesium, and Epsom salt corrects this deficiency. This leads to a healthier, fuller crop, that ends up tasting twice as good as you thought it could!

As an added bonus, this natural method is better than most chemical ones! Chemical fertilizers only enhance these deficiencies by leeching nutrients out of the soil themselves, so using Epsom salt is really a more effective solution.

To put this to work, dissolve 2 tablespoons in a gallon of water, then just simply water your plants. Bi-weekly feeding should suffice, and you’ll literally taste the difference!

Stop leaves from curling

Epsom salt can also be used in a mixture with water (2 tbsp Epsom, 4 litres water) that stops leaves from curling unhealthily. This is because leaf curling may well be related to a deficiency that the hydrated magnesium is able to solve. Take the mixture and directly coat the leaves to prevent the curling properly.

Sweeten your produce

Epsom salt is associated with higher levels of chlorophyll. Higher levels of chlorophyll means higher levels of sugar, which of course means higher levels of sweetness. This is a fun side effect of Epsom salt, it really brings out that healthy sweetness in fruit.


Epsom salt has a variety of uses within the garden. Its greatest benefit seems to be how naturally it works with the produce, providing a much needed alternative to chemical additives in the garden. Epsom salt in fact breaks down within the soil to its base components, magnesium, sulphur, and water, to best benefit the plants without negatively impacting the pH levels of the soil.

Epsom soil is cheap, easy to use, and helps with a variety of plants. Really, what better tool could a gardener ask for?
