Did you know that to avoid magnesium toxicity, the calcium content of the soil needs to be at least 10 times higher than the magnesium. So adding Epsom salt alone can cause that imbalance and create a toxic environment for the plants trying to grow. What many seem to ignore or not think about is that the excess ends up somewhere , most often as a pollutant or contaminant in the environment especially waterways.
Since additional magnesium is rarely needed get a soil test done why potentially bring more harm to our already struggling environment? Getting your soil tested will tell you what it really needs instead of guessing based on misinformation. The urge to use common household products as garden fertilizers and pesticides is compelling for many gardeners who want simple, cheap, and what may seem to be harmless.
For some reason, we feel if we can use it and or consume it then it must be safe to put in the garden. The science behind any use of Epsom salts in gardening is only applicable in intensive crop production where it is known to be deficient in the soil. Therefore it is highly irresponsible to advise anyone to use Epsom salts for plants in the garden, on houseplants, or in the landscape without regard of what it can harm in the environment.
If your garden does not need the addition of magnesium sulfate then using Epsom salts will only create problems not enhance your gardening efforts.
Final thoughts.. Take a lesson from forests and wild lands, growing lush and beautiful without the addition of anything bagged, mixed or mans misunderstandings of what the soil needs. Your garden can be the same inexpensively and you will be working with nature and not against it. Learn how to feed your soil and it will care for your plants. It is also sold as a laxative and magnesium is good for that but I feel it is much easier to take a capsule than drink Epsom Salts.
Resources: Washington State University , N. I consulted an advocado farmer as to why my advocado wasn't producing any fruit. I was advised to feed them Epson salts, the next season the tree bore fruit for the first time and I've used it ever since with great results. I am glad it worked for you but typically magnesium is not the only nutrient missing when something goes awry.
Have you had your soil tested to see what else it may need. Just adding the Epsom Salts will eventually lead to a larger imbalance and create more problems, finding out the real issue is important. Adding organic matter to your soil is a better way to go about balancing the nutrients in it without the risk of overusing one component.
I was going to try epsom salt as I read on Pinterest but thought I should research further and found this. Thank you so much! Good article. Always interested in good counterpoint. Live in Central Florida. Very sandy soil and watching podocarpus hedge leaves and plant dry up and die. Many point to magnesium depletion in sandy soil. Willing to consider other suggestions but am going to need to act quickly or lose well established plants.
And even then, most good fertilizers have the magnesium in them and will do that job. Rarely is magnesium the only nutrient that is deficient. Hi Pamela, Just joined your site. Question for you: are you by any chance a Master Gardener? Pamela, Thanks Pamela, please keep up your work in educating the ignorant.
With the tools and science we have today anybody that is truly interested can educate themselves. No I am not I am self educated. I was not impressed with the Master Gardener program in our area when I gave it a try. I'm Pamela, author of Flower Patch Farmhouse.

Saturday 22nd of May Chris Monday 3rd of May Pamela Tuesday 4th of May Sandy soil is an exception and does lose magnesium quickly. So give it a whirl. Tomato plants with Epsom salts are also resistant to yellow leaves and wilting fruits. Pepper plants enjoy magnesium as well.
Tomatoes and peppers greatly benefit from Epsom salts, especially around the time of their flowering stage. When beautiful yellow tomato flowers or white pepper flowers begin to grow, get your Epsom salt and mix 1 tablespoon per one gallon of water and spray liberally. Do this twice a month. You can also try sprinkling Epsom salt around the soil of your tomatoes and peppers for more direct effects on the root level.
For this method, you may want to use this compound with other fertilizers. Epsom salts are best used to make the soil more fertile and productive for plant growth, so try to add this compound to your soil before you begin your garden. Before using Epsom salts, make sure to check your soils with a soil test to know how much of it to add.
The sulfur found in Epsom salts helps to dissolve calcium found in the soil, while magnesium improves the quality and acidity of the soil. To reinvigorate your soil with nutrients, mix 1 cup of Epsom salt to a gallon of water and drench it all over the ground to heighten the levels of magnesium and sulfur.
Repeat this process for all parts of your garden and wait for 2 weeks before planting. Some areas in the United States, like Mississipi, already have enough magnesium in the soil, so check your local area before trying this method. Magnesium deficiency is one of the main reasons Epsom salts are so useful: this compound helps to replenish magnesium and adds nutrients naturally. The signs of magnesium deficiency are common in many plants. If the foliage of your plants is turning yellow, especially around the veins of the leaves, this may be a sign of deficiency.
Other signs include the green color of the foliage starts to look pale, browning, or even red. Overwatered plants usually look limp and weak, with mushy black roots. To use Epsom salts to replenish magnesium-deficient plants, mix 1 tablespoon per gallon of water and drench all over the soil like regular water, or spray the mix over your plant leaves.
Did you know that you can use Epsom salts for seeds, too? As a seed starter, a diluted mix of Epsom salt 1 teaspoon per gallon of water can help germinate seeds faster. Adding Epsom salt to your usual water soak before putting your seeds on soil can help plants grow. Not only does this help in growing stronger cell walls; seeds have a headstart from being magnesium-deficient, too!
Epsom salts can be used as a beneficial fertilizer for most plants. As a general fertilizer, Epsom salts are best used when sprinkled around the bases of plants. Many rose gardeners swear by the use of Epsom salts to their plants, and for good reason: Epsom salt is said to produce more flowers and stronger stems! Rose plants, in particular, are susceptible to magnesium deficiency. This garden favorite is vulnerable to brown spots in its foliage because it craves magnesium just as much as it loves water.
Try using Epsom salt to combat magnesium deficiency and see the results for yourself. Be careful when applying Epsom salts, especially on roses.
Rose flowers, white ones in particular, are susceptible to burning if Epsom salts are placed on a sunny day. Try this method every month to strengthen the cell walls and general health of your roses. Other flowers that benefit from Epsom salts include Chrysanthemums, Sunflowers, and even some orchids, too! Does your garden suffer from a pest problem? Fear not, the magnesium sulfate power of Epsom salts might be able to help! Sprinkle a small amount of Epsom salt around the soil of your garden, or apply it close to the base of your plants to deter small bugs from coming back.
This natural method could potentially end your pest problem in the meantime. Many plants will struggle to grow in soils that are too alkaline, and so reducing the pH level of the soil in these instances will be very beneficial. The Epsom salts should be worked into the soil, and will gradually increase the acidity of the soil over time.
Epsom salts are known to be beneficial to some plants in some situations. Primarily, roses, tomatoes, and peppers are the key plants that can take advantage of the magnesium levels contained in Epsom salts. However, there are some situations in which Epsom salts should not be used. These are as follows. Epsom salts contain micronutrients which are beneficial to the health of many plants.
However, the main nutrients which plants require are nitrogen, phosphorus, and potassium, which are referred to in the gardening world as N-P-K. The nutrient value of Epsom salts is , meaning they contain no traces at all of nitrogen, phosphorus, or potassium. Epsom salts do not contain any of the essential nutrients a plant needs, and instead, you should be feeding your plants with a balanced fertilizer to help sustain them. Epsom salts can be beneficial, but they should be used as an additional secondary supplement, and not as the primary means of feeding a plant.
If you have found that your plant is magnesium deficient, you might instantly assume that your soil is lacking magnesium. Some plants suffer from magnesium deficiencies because the soil is too high in phosphorus, which prevents a plant from being able to adequately absorb the soils magnesium.
Adding Epsom salts in this instance will not make any difference because it is the phosphorus level of the soil, which needs to be decreased to enable a plant to absorb magnesium. Treating the soil with Epsom salts will be pointless and will delay you find the real reason that your plants are not thriving. It is important to have your soil tested to determine the correct problem before mistakenly treating it for a deficiency.
Epsom salts can be useful at helping to neutralize alkaline soil, and so the opposite would be true in acidic soil. If you have acidic soil, then you should refrain from using Epsom salts in your garden, as this could exacerbate the problem.
There are many different ways to use Epsom salts in the garden, and the ratio you can use will differ depending on the application method, and the plants you are treating. For a general Epsom salt supplement that can be used in the garden and on houseplants, use two tablespoons of Epsom salt per gallon of water, and use this to water your plants once each month in between regular watering.
For roses, work in half a cup of Epsom salts around the base of the plant to encourage new growth and flowering.
