What is Epsom Salt?

Epsom salt is a mineral found in water carrying massive levels of magnesium and sulfate. It was found in the town of Epsom in England early in the 1600s. This salt is similar to table salt. It has no sodium chloride and is technically known as magnesium sulfate.

It has since been adopted for healing various conditions in plants, animals, and also in humans. Chemically, Epsom salt has 13% sulfur and 10% magnesium. These are nutrients that are vital for several plant development and growth.

How to Apply Epsom Salt to Plants

Generally, Epsom salt used int the garden as a foliar spray. You can add the required amount of Epsom salt with water and spray it on a plant’s leaves. You can do this method in the season when fresh leaves are appearing, and you can reapply this method after flowering. While planting, you can use Epsom salt directly to the soil. It works on the ground without diluting it in water.

Is Epsom Salt Uses Good for Plants?

The answer is Yes, The traditional advantages of Epsom salts aren’t limited to just People. Plants can get benefits from it too. Various studies have explained that Epsom salt (Magnesium sulfate) is useful to plants early on. There look to be valuable, important reasons for using Epsom salts on your plants. Epsom salt helps to enhance flower growth and improves a plant’s green colour. It can also help plants grow thicker.

Epsom salts— are a chemical compound, the general name hydrated magnesium-sulfate (MgSO4). It has numerous benefits to essentially anything you wish to grow. Magnesium-sulfate (which seems like regular table salt) can improve nutrient absorption in plants. Magnesium sulfate provides two necessary nutrients to plants – magnesium and sulfur, which is essential for plant growth. Magnesium allows plants to better take in valuable nutrients, like nitrogen and phosphorus. Also, magnesium hugely promotes a plant’s energy to produce fruits and flowers.

Acidic Soil

Epsom salts can be beneficial at improving to neutralize alkaline soil, and in acidic soil, it would be the opposite. You should avoid applying Epsom salts in your garden if you have acidic soil, which could increase the problem.

Precautions Before Using Epsom Salt For Plants

Before using Epsom salts in the garden, be conscious of some cares. Technical or Agricultural category Epsom salts are intended for garden and outdoor uses. Still, only brands tagged “USP” are suitable for humans, approved and tested by the FDA. Epsom salts have natural laxative characteristics, so keep bulk salt away from pets and children. Magnesium-sulfate is absorbed into the skin as well. So always use gloves when using salt to your garden plants. First, examine your garden soil to learn what minerals are low. Epsom salts are toxic for soil unless you have a soil test that tells your garden soil is low in magnesium.

Does Epsom Salt Work as Fertilizer?

Epson salts do not provide perfect fertilizer for every plant. Suppose you’re trying to enhanced fertility with Epsom salts. Your plants are more beneficial with combining compost or organic manure. Both of these choices will provide a wide array of macro and micronutrients to your garden plants. Mixed with proper watering, they’ll give healthier and larger plants!

What is Magnesium Deficiency In Plants :

Magnesium is a necessary component of plants. It describes a structure block for chlorophyll known green leaf color in plants, and hence, it is vital for photosynthesis.

Magnesium Deficiency Symptoms In Plants:

When plants are magnesium deficient, the leaf green in the ordinary mature leaves under the flowering tip will be split up, and the magnesium will be moved into the young and growing portions of the plant.

This division is apparent as vague, reddish-brown spots, dark or yellow spots among the veins, Leaf curl, or early leaf fall. A small deficiency of magnesium rarely affects flowering, although the flowers’ progress makes the deficiency signs more critical. Magnesium deficiency is common in apples, tomatoes, raspberries, grapevines, rhododendrons, and roses.

Cause of Magnesium Deficiency In Plants :

Magnesium is required for pure leaves and for plants to provide energy from the sun (photosynthesis). Soil deficits of magnesium are more natural on daylight, sandy soils. Over usage of leading potassium fertilizers can begin magnesium loss, as plants use potassium in preference to magnesium.

Magnesium deficiency solution for plants:

Before using Epsom salt, a good idea to have your soil tested to determine whether it’s deficient of magnesium. When magnesium deficiency is diagnosed in soil, make an Epsom saltwater with the rate of 20g of Epsom salts per litre of water. Apply once or twice a month, by spraying in normal weather to avoid leaf scorch.

Attention: Epsom salts sprayed on leaves can create leaf scorch. Do not use extra and do not sprinkle on warm, shining days.
NOTE: It is regularly prudent to have a soil test completed before using any nutrients to the soil.

Epsom Salt Uses For Gardening

Epsom Salt is hugely suggested by expert farmers to use on your vegetables.
It is relatively secure, economical, and the benefit of combining it to the soil to increase the plant’s health.
It has been applied in gardens for several years as a “fertilizer.” When diluted or sprinkled or used as drenching water, it is immediately “available” for plants.

1. Give Seeds a Better Start

Epsom salt is perfect while seedling germination. It is highly solvable in water and has a neutral PH. This salt gives a boost to the new plant because it emerges from its seed coat. When you use Epsom salt in the garden, the germination speeds will likely be higher because the seedlings will be much healthier.

Magnesium boosts the seed germination process by strengthening cell walls and improved the energy for growth.
Whether large or small, any seeds have related germination requirements for healthy growth like water, light, and air. Many expert farmers recommend using a soilless mixture for starting seeds.

To do this, add one tablespoon of Epsom salt into an individual seedling drench before planting.
You are sowing your seeds before adding Epsom salt to the soil because you provide the extra nutrient supply that wouldn’t have been available otherwise.

This magnesium-dose jumpstarts your seedlings’ germination process and promotes plant health for the remainder of their life cycle. Spray one cup of Epsom salts per 100 square feet for wildflowers and grass seeds, mix into the water and soil thoroughly. Reapply an Epsom salt drench to seedlings every month throughout the growing season.


Nope. Magnesium is indeed a substantial part of the chlorophyll molecule. Often most soils are not magnesium deficient, then treating chlorosis with extra magnesium (Epsom salt) is inefficient. Many times in the soil, chlorosis is a lack of iron, not magnesium. Applying an iron supplement is most suitable for your garden. If you use magnesium instead of iron, you can only develop the difficulty for your plants.

3. Boost Flavor

Each month throughout the growing period, add one tablespoon of Epsom salts to one gallon of water and use it to the roots of the fruits like grapevines, nut trees, and berry patches.
Another procedure is to use two tablespoons of dry Epsom salts over a root-bed area, use this method three times a year.

Tomatoes and sweet peppers additionally get an advantage from applying some Epsom salt to the garden soil. Add one tablespoon of Epsom salts to the soil of all holes Before planting seeds. Use a foliar shower of two tablespoons of Epsom salts per gallon of water during the growing season. Apply this spray to leaves once a month.

4. Deter Pests Naturally

To destroy snails and slugs, expel the pests with Epsom salts instead of using traditional table salt. In this method, you will provide a boost to roots and blooms. For common pest control, take five gallons of water and add one cup of Epsom salts. Then sprinkle onto foliage. For slug and snail control, sprinkle dry Epsom salt throughout the bed of plants in the garden.

5. Prevent Leaf Curl

Another sign of a magnesium deficiency in your plant is leaf curl. Leaf curl is when the peaks of the leaves curl inside towards the rest of the leaf. To resist this, use Epsom salt to your garden soil to improving the magnesium levels.

6. Prevent Root Shock

It’s no wonder that when shifting plants to another place, roots can be injured. This force leads to transplanting shock – when a plant unable to efficiently root itself on a new location due to rapid environmental variation or root injury. Usually, this produces the plant to wilt and can ultimately result in mortality.

But this transplanting shock can be treated using Epsom salt to the soil of a new location where the plant is staying restored. The Epsom salt triggers chlorophyll creation, which supports more effective nutrient absorption, which improves healing.

Transplanted roots require delicate attention. To prevent root shock, which causes leaf discoloration and wilting, add one tablespoon of Epsom salts per gallon of water and use it over the roots of anew re-potted plants. The second method is trying to adding one teaspoon of dry Epsom salts direct to the hole before transplanting your plant.

7. Heal Your Houseplants

House plants are not as lucky as our garden plants in that they carry extreme volumes of nutrients in containers.
If you supply your houseplants, an equivalent fertilizer with all the essential macro and micro-nutrients to add extra magnesium and sulfur will only succeed in a build-up.

Epsom salts are pH neutral and peaceful on plants, and also on potted houseplants. To increase nutrient absorption, add two tablespoons of Epsom salts per gallon of water and sprinkle onto the leaves of the plants, for the greatest nutrient intake. Or add the Epsom salts direct to the soil in the rete of one teaspoon of salts per foot. Every month, try to apply Epsom salts to your houseplants and observe subtle differences in leaf growth and vibrancy.

8. Increase Nutrient Absorption

Experimental examinations indicate that magnesium-sulfate can enhance cell uptake of essential minerals, including phosphorus, nitrogen, and sulfur.
In one new research, examiners in five states supplied pepper plants a regular drench of one tablespoon of Epsom salts per gallon of water, and use it twice a month, and most of the treated plants exposed thicker foliage and bigger vegetables.

9. Grow a Lush Lawn

If your garden soil inspections positive for magnesium lack, Epsom salts will improve your lawn, produce the greatest lushness and growth. The Epsom Salt Council suggests implementing three pounds of Epsom salts per 1,250 squared feet of lawn with a spreader. Spatter the salts slightingly, then water your garden with a pipe or spray system.

10. Yellow Leaves

Yellow leaves usually indicate the plant requires the essential nutrients magnesium. Use Epsom salt (magnesium sulphate), mix it to compost put in the soil once or twice a month.

11. Fruit Trees

Producing fruits for a tree is a lengthy method. Magnesium levels usually down through the “long season,” where Epson salt applying can significantly help.
Increased photosynthesis, More effective plant growth, fruit can taste fresh, be extra nutritious, look extra charming, and disease and weather resistant. Use three times per year, two tablespoons per 10 square feet above the root.

12. Epsom Salt for Tomatoes and Peppers

Peppers and Tomatoes may expose symptoms of lack of magnesium in the season when their leaves start to yellow among the leaf veins, and the plant drops the fruit production.
You will get more abundant fruits if you are applying Epsom salts. There are two methods to use.


add one teaspoon of Epsom salts into the planting hole soil when placing out transplantings.

Method 2:

Add one tablespoon of salts per gallon of water and water the seedling.

When the plants begin to flower, or fresh fruits start to form, follow-up with a foliar spray. To make foliar spray add one tablespoon per gallon of water. Test this spray on a few plants and examine the result.

There are various methods for applying this gardening remedy to your home gardens.
Many expert gardeners simply use Epsom salts at planting time. Others prefer to water or foliar feed with Epsom salts twice a month.

When sprinkling straight on the leaves, apply a dilute liquid, adding one tablespoon of magnesium salts per gallon of water, because it is not remembered for sure whether excess salts will mix up in the soil or move through the water supply. Many gardeners just use magnesium salts when they remember.

13. Epsom Salt for Roses

Rose growers, mainly, are strong advocates for the usage of Epsom salts. They challenge it and gives the foliage fresher, lusher, and greener, however, it also produces fresh roses. The guidance for using Epsom salt to current rose bushes is to add half a cup of Epsom salts into the soil nearby the rose bush. For continuous rose care, mix the half cup of the salts in one-gallon water and apply as a foliar spray around the rose bush.

If your rose bushes are more abundant, you may require several water gallons for Epsom salts foliar spray. Caution: Do not over apply and do not spray on warm, sunny days.


Epsom salts carry micronutrients and are a helpful supplement for many plants, like tomatoes, roses, and peppers. It can support better soil quality in some cases, though it would be harmful to others, such as in acidic soil. Epsom salts do not carry any necessary nutrients, and hence it should not be applied in the area of a well-balanced fertilizer.
