Epsom salt has been used by people for plants for a long time. The internet is full of emotional appeals for this product.
Some people spray a mixture of epsom salt and water on their plants, believing that it will kill pests, make their tomatoes grow larger, prevent fungal diseases on the leaves of their roses, and work as a weed killer. Some gardeners believe that epsom salt can help cure blossom end rot and make plants stronger.
However, it is strange that when you put all of the assertions of miracles together, they do not seem to fit. Wouldn’t it be amazing if there were a product that could kill weeds without damaging your desired plants, and somehow make them stronger at the same time? Can one product really kill off all garden pests?
Epsom salt is a mineral compound containing magnesium sulfate. It has long been claimed to have a variety of benefits, including reducing stress, helping muscles recover, and improving sleep quality.
What is Epsom Salt?
A naturally produced mineral consisting of magnesium and sulfur, Epsom salt is more commonly known as Magnesium sulfate (MgSO4). Magnesium sulfate readily dissolves in water, releasing magnesium ions, which are positively charged, and sulfate ions, which are negatively charged.
The name of Epsom salt is derived from the town of Epsom in England, where the waters are rich in magnesium sulfate and have been used in local spas for centuries.
Epsom Salt In The Garden: Pros and Cons
If you look quickly through the internet, there are many ways to use epsom salt. We will investigate some of the ways people use epsom salt and if they are truly helpful!
Blossom End Rot
The most common use for epsom salts is to treat tomatoes and peppers for blossom end rot. Epsom salt can be beneficial to plants in two ways: either by placing a tablespoon of it in the soil before planting, or by dissolving it in a gallon of water and spraying it on the plants as a foliar spray.
Blossom end rot is a problem that occurs when there is a calcium deficiency in your plants. Most often, it’s directly linked to irregular watering. If the soil is dry, then the plants will have a difficult time absorbing nutrients from it. This can then lead to various deficiencies. Using timed drip irrigation can prevent blossom end rot.
Epsom salt contains no calcium. If your tomatoes have blossom end rot, adding magnesium and sulfur could make the condition worse. An overabundance of any one nutrient in the soil can lead to calcium deficiencies. An excess of magnesium in the soil can counteract the effects of the natural calcium, making it a dangerous additive to use when trying to treat blossom end rot.
Once pepper and tomato plants are old enough to start setting fruit, phosphorus becomes more essential for their growth and development. Fertilize your tomatoes and peppers with a balanced fertilizer in the early part of the year, but use a fertilizer with less nitrogen and more phosphorus when the fruit starts to develop. Soil testing is important to do every year to determine if fertilization is necessary. Many home gardeners have soil that is already nutrient-rich.
It is not recommended to use epsom salts to treat blossom end rot. While it’s a common garden myth, it’s inaccurate.
Pest And Disease Control

People have been claiming for many years that epsom salts can help reduce the population of garden pests. However, there is not enough evidence to support this claim. Epsom salt can also be used as a foliar spray to improve plant health and treating plant diseases.
There is no evidence that epsom salt can help plants resist pests or diseases. If you spray epsom salt on plants, it will cause the leaves to scorch.
Sulfur by itself is helpful in getting rid of some pests, but adding extra magnesium doesn’t do much. It is necessary to target specific garden pests or diseases with specific methods of control, rather than using an improvised solution.
But what about the sulfur in epsom salts? Sulfur is commonly used to treat rust and powdery mildew. There isn’t enough sulfur in magnesium sulfate to make it effective. If you wish to use sulfur, it is better to choose soluble sulfur instead and forego the magnesium in epsom salts.
Epsom Salt As A Fertilizer
Some people say epsom salts are a good fertilizer to keep plants from getting magnesium deficiency problems.
It’s important to remember that nitrogen, potassium, and phosphorus are essential nutrients that most plants need. Nitrogen promotes foliage growth. Phosphorus promotes healthy flowering and fruit production. Potassium is essential for plant health and growth. It helps develop strong roots and foliage, and increases the resistance of plants to disease and drought.
While magnesium is an essential micronutrient that plays a major role in photosynthesis, many plants do not need a lot of it in their soil. If your soil is deficient in magnesium, adding epsom salt can help. If you use garden epsom, it can actually reduce the uptake of other nutrients that are more essential.
A phosphorus excess can often give the appearance of magnesium deficiency in soils. Home gardeners who do not soil test annually may end up with an excess of NPK nutrients if they fertilize heavily. A symptom that resembles a magnesium deficiency may occur even when magnesium levels are normal.
A magnesium deficiency can occur in commercial croplands with acidic sandy soil. This is because magnesium deficiencies are typically found in areas with intensive planting. Commercial cropland is often deficient in the major nutrients nitrogen, phosphorus and potassium, as well as magnesium, iron or calcium, and sometimes other micronutrients. The use of high-potency fertilizer in commercial agriculture boosts nutrient levels overall. A soil test should be done before adding any amendments to ensure the correct mix of nutrients is applied.
Germination Aid
There is a claim that epsom salt, because it contains magnesium and sulfur, can help seeds germinate faster. Unfortunately, this too is a common gardening myth.
A fully-developed seed is a complete package. The inside of a seed contains an embryo of a plant as well as a store of food, which is surrounded by the seed coat. You don’t need to worry about food, you can grow seeds on a paper towel or sprouts in a jar. The three things needed for seed germination from the outside world are light, moisture, and the right temperature. Without oxygen, the embryo inside the seed will die.
Most seeds will germinate on their own. While epsom salts are often touted as a way to improve germination, applying magnesium and sulfur won’t actually provide any benefits.
Weed Killer
There is no scientific evidence to suggest that epsom salt on its own is a weed killer. It is possible for this chemical to damage plants, but it would require a large amount to be present in the soil or for it to be applied directly to the leaves.
The only recipe I have found for this practice is to mix 1 cup of epsom salt with 2 gallons of vinegar, and then spray the mixture on weeds.
Household vinegar is not very effective against weeds. Vinegars used for agricultural purposes are typically 15-20% acidic, whereas household vinegar is only 3-5% acidic. Agricultural vinegar is a very strong acid and it can burn your skin. Any substance that can burn you is probably also effective in killing weeds.
How To Apply Epsom Salt on Plants:
Method 1: Epsom salt as a foliar Spray during Growing Season
An Epsom salt foliar spray is the most effective way to use Epsom salt in the garden for efficient plant growth. Epsom salt foliar spray is a way of feeding a plant through its leaves rather than its roots.
It is true that feeding the plants through the leaves will never completely replace proper soil preparation to feed the plants, but plants prefer to take in nutrients through the leaves rather than through the roots and stems.
Fertilizing your plants with a foliar feed will help to provide the micro-nutrients required by the leaves of the plants, especially when the plants are under stress from unfavorable weather, pests, or diseases.
You can make a foliar spray out of Epsom salt very easily.
Method 2: Epsom salt as Side-Dressing during the Growing Season of the plant:
Epsom salt can help your plants grow by using it as a mulch or a side-dressing. If you have sandy soil in your garden, this technique is very easy. Sandy soil doesn’t hold nutrients well.
Epsom salt is highly beneficial to plants during the sprouting period, as they require a lot of nutrients during germination. In general, plants that require a lot of nutrients to grow (heavy feeders) such as eggplants and peppers, will produce more fruit when given this type of fertilizer.
Method 3: Epsom salt as a Soil Additive at Planting Time:
Epsom salt can be an excellent supplement for your soil when planting. This method improves the plant’s growth from the start, and has a positive overall impact on the plant growth and yields. You should try out this method when planting green pea seeds.
Magnesium plays a key role during the germination. This element strengthens cell walls, creating stronger seedlings that can resist transplant shock. You will have the best germination rate if you use Epsom salt.
Method 4: Epsom salt for Grow Bigger Blooms
The Epsom salt is the medicine that you need for your rose bush to yield a lot. Epsom salt, which contains magnesium, will increase chlorophyll production. This results in leaves that are darker in color and rose plants that are hardier. The blooms and growth of new canes at the base of the plant will be larger.
The sugar in Epsom salt will help nourish the helpful bacteria in the soil, which will aid in breaking down the nutrients in the soil, making them simpler to take in. This process makes the plants produce bigger blooms.
Method 5: Epsom Salt to Kill Weeds
Weeds are a big issue when it comes to gardening, but Epsom salt is the best solution for getting rid of them. It’s an all-natural and effective way to kill weeds in your garden.
Epsom salt, dish soap, and white vinegar can be used to kill weeds. Weed growth can be removed by vinegar, which extracts the moisture, and by dish soap and Epsom salt, which will help to burn them out.
To get the best results, use the weed killer on a day when it will be hot and sunny, and make sure there is no rain in the forecast for at least two days.
Method 6: Epsom Salt for Growing Tastier Vegetable:
Epsom salt can help you grow healthy and delicious vegetables in your garden. Epsom salt can help improve plant growth for tomatoes and pumpkins.
Do Epsom Salts Really Help Plants Grow Better?
Many researchers are very impressed with how well Epsom salt works on plants, but some may think it is wrong to continue using it. Epsom salts are highly beneficial to gardeners. If you’re planning on using Epsom salt to fertilize your garden, it’s a good idea to test your soil first. That way, you’ll know how much to add, and you won’t risk adding too much. Epsom salts will not fix a severe magnesium deficiency and are more useful in acidic soils, where magnesium is not readily available to plants. Epsom salts are most often recommended to Tomato, Pepper and Roses plants.
