Salt-tolerant plant growth-promoting rhizobacteria (ST-PGPR) are potential solutions to the problem of soil salinity, which limits plant growth and yield. These bacteria can synthesize phytohormones that promote increased root number and length, enhance water and nutrient absorption in saline soil, and ultimately enhance crop yield. Soil salinity is one of the main abiotic stresses that limit plant growth and yield. Plants under salt stress have significantly reduced productivity, and the extent of this reduction is influenced by the presence of rhizosphere bacteria.
Salt-tolerant PGPR can increase crop yield through improving soil fertility and stress resistance. Previous studies have shown that salt-tolerant PGPB elicit better plant survival under salinity, making them potential candidates for enhancing agricultural productivity. Salt stress negatively affects plant growth and reproduction in many ways, producing nutritional and hormonal imbalances. Various genera of ST-PGPR have been isolated from extreme alkaline, saline, and sodic soils, and many of them are known to mitigate various biotic stresses.
Salinity affects production in crops, pastures, and trees by interfering with nitrogen uptake, reducing growth, and stopping plant reproduction. While some plants native to saline environments grow better with salt in the soil, salt is harmful to the vast majority of plants. Sodicity refers specifically to the amount of sodium in the soil, and adding salt to water is not likely to help plants grow better than plain water.
📹 Hidden Dangers of EPSOM SALT in the Garden
Using Epsom salts in the garden is a given…right? I mean it does so many things. Right? In this video I will break down the claims …
Is salt water good for growing plants?
Salt water directly harms plants by accumulating toxic chloride and sodium ions and creating chemical drought. Timing is crucial, with active growth causing greater damage, while crops at the end of their life cycles may experience less damage. The longer plants experience salt water inundation, the greater the toxicity. Salt is readily soluble and leaches out of the soil with successive rains, with soil texture playing a significant role. Porous, fast-draining soil, like those in southern Florida, will leach salt faster.
Can salt be given to plants?
Deicing salt, the most common rock salt used to melt ice and snow on roads and walkways, can be harmful to trees and shrubs due to its ability to absorb water and pull it away from roots and tissues. As the salt dissolves, it splits into sodium and chloride ions, which affect the plant’s ability to uptake essential nutrients like potassium and magnesium. Additionally, chloride ions interfere with photosynthesis, diminishing the plant’s overall health and causing various damage.
To detect salt damage in plants, evergreens may show signs of salt injury, while deciduous trees may not be visible until spring growth continues. Common warning signs include:
- Decreased root growth

Is salt good for plant Fertilizer?
While sea salt does contain nutrients that can be used as fertilizers, there are other sources that are more concentrated and desirable, and which pose less of a risk to crop growth.
Can I put salt around my plants?
While salt spray is an effective method for controlling slug populations, it is important to avoid over-sprinkling, as this can lead to adverse effects on plant health. Slugs represent the lowest trophic level in the food chain, providing food for carnivorous predators. It is recommended that measures be taken to encourage the presence of badgers, birds, and hedgehogs in order to reduce the population of slugs.
Chickens can be a beneficial addition to a garden, providing a source of eggs on a daily basis and helping to reduce the population of slugs. Furthermore, adopting an ex-commercial farming hen may prove beneficial.
Is salt good for potted plants?
Soluble salts are minerals dissolved in water, which can cause plants to struggle to take up water after evaporating from potting soil. As salts become more concentrated, plants struggle to take water from their root tips, leading to death. To combat this issue, water plants correctly, ensuring some water drains through the pot and emptying the drip plate. Avoid allowing the pot to sit in water, as drained water can be reabsorbed by the soil, causing salts to be reabsorbed back into the soil.
Which salt is used for plant growth?
Epsom salt, which is renowned for its beneficial effects on humans, has been demonstrated to facilitate the growth of plants, enhance their flowering capacity, and improve their coloration. Furthermore, it facilitates seed germination and acts as a repellent for slugs and other pests commonly found in gardens.
How much salt is safe for plants?
Water with a relatively low amount of salt, such as less than 0. 7 decisiemens per meter or less than 450 milligrams per liter of total dissolved solids, can be used to irrigate most plants without harming them, including salt-sensitive ones. To irrigate with water containing higher salt, extra management practices may need to be implemented, such as growing salt-tolerant plants and irrigating enough to leach salt beyond their roots. Recycled water typically has a slightly higher concentration of salt than its origin water, with an electrical conductivity ranging from 0.
6 to 1. 7 decisiemens per meter. Plants can be injured if sodium exceeds 70 milligrams per liter in water, 5% in plant tissue, or 230 milligrams per liter in soil, in the extract from a saturated soil paste. Plants are usually injured by chloride if it exceeds 350 milligrams per liter in water, 1% in plant tissue, or 250 milligrams per liter in soil, and by boron if it exceeds 1 milligram per liter in water, 200 parts per million in plant tissue, or 5 milligrams per liter in soil.
Does salt improve plant growth?
Soil salinization is a significant issue in agriculture, particularly in hot and dry regions where soils are often saline with low agricultural potential. Inadequate irrigation management leads to secondary salinization, affecting 20 of irrigated land worldwide. Irrigated agriculture is a major human activity that often results in secondary salinization of land and water resources in arid and semi-arid conditions.
Soil salts occur as ions, released from weathering minerals in the soil, applied through irrigation water or fertilizers, or sometimes migrate upward in the soil from shallow groundwater. When precipitation is insufficient to leach ions from the soil profile, salts accumulate in the soil, resulting in soil salinity.
Salinization is recognized as the main threats to environmental resources and human health in many countries, affecting almost 1 billion hectares worldwide, representing about 7 of Earth’s continental extent. In India, an estimated 7 million hectares of land are covered by saline soil, most of which occurs in the indogangetic plane. Arid tracts of Gujarat and Rajasthan and semi-arid tracts of Gujarat, Madhya Pradesh, Maharashtra, Karnataka, and Andhra Pradesh are also largely affected by saline lands.
Soil salinity affects almost all aspects of plant development, including germination, vegetative growth, and reproductive development. It imposes ion toxicity, osmotic stress, nutrient deficiency, and oxidative stress on plants, thus limiting water uptake from soil. Soil salinity significantly reduces plant phosphorus (P) uptake because phosphate ions precipitate with Ca ions. Some elements, such as sodium, chlorine, and boron, have specific toxic effects on plants, leading to osmotic stress and cell death. High salt levels in the soil can upset the nutrient balance in the plant or interfere with the uptake of some nutrients.
Salinity also affects photosynthesis through a reduction in leaf area, chlorophyll content, and stomatal conductance. It adversely affects reproductive development by inhabiting microsporogenesis and stamen filament elongation, enhancing programed cell death in some tissue types, ovule abortion, and senescence of fertilized embryos. The saline growth medium causes many adverse effects on plant growth at physiological and biochemical levels, as well as at the molecular level.
How much salt is too much for plants?
Plants can be injured by sodium, chloride, and boron if their concentrations exceed 70 milligrams per liter in water, 5% in plant tissue, or 230 milligrams per liter in soil. Chloride can cause damage if it exceeds 350 milligrams per liter in water, 1% in plant tissue, or 250 milligrams per liter in soil. Boron can cause damage if it exceeds 1 milligram per liter in water, 200 parts per million in plant tissue, or 5 milligrams per liter in soil. Recycled water from a specific water source can also be used to irrigate plants without harm.
Can we use table salt for plants?
The term “salt” should be defined specifically as sodium chloride (NaCl), the common salt used in kitchens. This salt is harmful to plants as it kills them by removing moisture and disrupting the pH balance, as it lacks the nutrients that plants can utilize.

The three key points I have learned are: Chloride is listed as one of the top 16 essential nutrients by soil scientists and it is critical …
Have never used, never been curious, never even thought about using epsom salt in my garden of all places. My rule of thumb with fifty years of gardening is to follow nature’s lead: whatever comes out of the ground goes back in. Nature has been following this method for millions of years. It’s worked great until human beings started interfering – ohhh, those chemical companies 🙁 Thanks as always for your honest good ol’ straight up information.
I learned rose care by my late mentor. Once a year she does a 2 part feeding and conditioning. Using her method and formula I’ve garnered professional industy awards for them. Epson salt is included in the once a year soil conditioning formula. If you’d like, you can do a search of her name, Bea Grow, and find an article in the Orange County Register from about 15 years ago on her. In it she descibes how she does it. A marvelous person. I miss her. Once someone asked her what she does about the wild rabbits munching their way through local gardens. Her blue eyes twinkled as she softly replied, “Oh, I suppose there’s enough for all”. I wanna “Bea” her when I “Grow” up.
Epsom Salts – named after the horse-racing town of Epsom in Surrey, south west England. There was (still is?) a large deposit of Magnesium Sulphate near the town a few hundred years ago, so the town became famous and very popular as a spa town for a while. It’s where the very first Derby race was run (named after the Earl of Derby), and it is still the premier flat race in the English racing calendar, and after which the Kentucky Derby was named and others around the world. Just saying …😊
THANK YOU ~ I have been telling people FOR YEARS that it did not make sense to use Epsom salt in our soil for plants we plan to eat. I thought it was excessive and could do harm. So many Google-researchers argued with me how they “read an article.” You now have something for me to share that MAYBE they will believe, because being a grandson of farmers who has gardened since he was a teenager and for decades they felt I wasn’t a good enough source.
My experience… For blossom end rot, I make a solution of a tablespoon of vinegar into a quart jar and pour a little on each plant as a top dressing on tomatoes and peppers at first sign of end rot. It allows the plant to have better uptake of calcium. It’s usually not a calcium deficiency, but a plant metabolism issue. The plant doesn’t have the metabolics to properly regulate its cell profile. Usually I see blossom end rot after a heavy rain. Just my experience.
I use it every once in awhile when my cannabis plants show a magnesium deficiency. I either use cal-mag or a little bit of Epsom salt and top dress with some crushed egg shells or crushed sea shells. I grew my first plants in 1975. When it comes to gardening you can never have enough knowledge looking forward to your next article catch you on the flip side of my brother. ✌️
I live in Georgia and use epson salts on my gardenias. I have the fullest and most blooms in the neighborhood. I apply it early spring and this makes them go crazy. I have an area that i haven’t used it on the gardenia plants and guess what? The leaves are yellow, they look like they are struggling and not blooming. I don’t use it on any other plants, only my gardenias.
I will say, Epsom salts were the only thing that truly worked like magic against slugs. I needed too much to treat every plant the neccessary amount so I chose a couple to target a large amount so they would live and sprinkled the rest. It saved my plants until they were big enough to fight it themselves. Beer traps work too but there are too many slugs to kill them all before they kill my plants.
In some regions in my country the soil is deficient in Magnesium. Magnesium Sulfate is sold in fertilizer shops in 50-lb bags for $20 and is used as “medium” fertilizers. (“Large” are nitrogen, phosphorus, potassium, “medium” are magnesium, sulfur, calcium, and “small” are the remaining trace elements). We dissolve 1 or 2 grams per liter of water. Without Magnesium Sulfate leaves stay yellow and never turn green. No one here even argues about the importance of Magnesium Sulfate. You loose your plants without it. Magnesium is at the center of the chlorophyll molecule, similar to how iron is at the center of the hemoglobin molecule.
I have never used epson salt either, up to now. I have just started today using a water soluble fertilizer mix, called Master Blend. Which includes both a magnesium sulfate / Epson Salt and a Calcium Nitrate. I have just started applying this blend to my starter plants, but I plan to add this to a fertilizer injector system that I have attached to several of my raised garden beds, to see how it does in that one section of my garden, before applying it to the other sections of my garden.
Brian, I’m disabled & have 2 dear friends that help me in the garden. Sometimes they can’t tell the difference between a weed & something I planted (& don’t even ask about the lovely ornamental fescue I planted that was repeatedly mowed to the ground till it gave up the ghost). Anyway, it would seem that epsom salt is smarter &/or more well educated than my to garden helpers. 😆
I was watering my seedlings with rain barrel water, kelp and fish emulsion. Wondered why they were pale green. I figured it was lack of calcium so i just put them in the garden. They’re greening up well now. I ordered up some calmag to add to my seedling mix for the next rotation. Plenty of calcium and magnezium in my city water but dont like sitting it out to wait for the chlorine to burn off.
I always stir a tablespoon of epsom salts in the hole when I plant my tomatoes. I think my mother always did. I have very little trouble with blossom end rot. Don’t know if it makes a difference. I get good crops with few problems. I only use containers and change out half the soil yearly. So who knows?
I used ES on my lawn of a house in McHenry County, Illinois. This was a house built on what had been farmland. The grass became noticeably greener after an application. On the other hand, at my current house in upstate NY, an application of ES to the lawn did absolutely nothing. I suspect the soil here already has plenty of magnesium from the underlying dolomitic limestone.
I’ve never heard all those claims, but I do know that many folks around here put a little in when planting a tomato. I occasionally use a product called Masterblend and I was informed that it worked best with Magnesium Sulfate and Calcium Nitrate. Filling a 2 gallon jug only requires 1/2 a teaspoon of epsom salt ( dissolved) . I only use it when the plants look really rough. I’m not very scientific. The combo of the three seems to pep up my plants. I target tomatoes and peppers with the mixture. I don’t know if it’s epsom salt, but I do use it 🤷🏼♂️
Though it should only be used in small amounts, We have extremely Sandy and alkaline soil with very little natural Organic matter. We must add everything: calcium and magnesium because they compete but the sulfur in epson salt also brings a somewhat neutral ph, Though sometimes I must add additional sulfur to get there. Admittedly our soil is very hard to grow anything in and most people won’t need it except possibly in potted plants.
I have cast iron bath tubs in my front yard with fire pits under them. I soak in them with epsom salt then drain it into my garlic patch. I hope its not hurting them. They grow huge bulbs on top that the hummingbirds love. The bulbs have cloves that are the size of my little fingernail and they are soooo good! I could eat them on or in anything. What a gift. I will have to pay more attention to my garlics.
Tomatoes and potatoes are native to South America. The soil there has a higher magnesium content than in North America. I use a little (1 teaspoon in a gallon of water) when tomatoes are producing fruit and when potatoes are producing tubers once every 2 weeks. Epsom salts are also a salt. Too much messes up the Ph of the soil and requires more water for that soil after harvest. This is not a problem with hydroponics where you can completely replace the water.
We are trying to grow Carolina allspice, also known by several other names. We are working with past hay field. We get yellowed leaves if we get any at all, 3rd try to grow these bushes. So looked up on Google and it said it is a magnesium and potassium defiance. So I put Epsom for soil and potash plus a little green sand around the plants. They are greening up. We have already used manure compost plus our home grown compost . That being said, we have already put a fish immulsion and root stimulator on these plants. They appear to be getting better but are still small and only have a few leaves. We had previously grown sunflowers. So I have no clue if any of this will keep them alive. Time will tell.
😂I don’t add Epsom salt to everything. But I do add them when my blueberry leaves turn red. Yes, I put in acidifier, sulfur, and everything you can think about adding to blueberry(mulch, etc.) FYI, sulfur takes time to acid the soil(up to a year, depending on the temp). Another reason why blueberry leaves turn red is the temperature in the soil. I can’t say the temp is high here, and this is a zone 6b near zone 6a. The average temp is 12-13C at night. I know, it is MAY. Anyway, if you know what you are doing, don’t be afraid to use Epsom salt.
I treat epsom salt like a trace mineral, very small amounts. A lot of inland soils are deficient in magnesium, and I’ve had good luck with it. Usually use it only in my container garden, not so much in the garden beds. 1 tsp per 5 gallon pot. Of course one doesn’t need to take advice from the producer of a product, they are just trying to sell ya something. As mentioned before, epsom salt is great for soaking a sore body after working in the garden.
How do these things get started and gain traction? Sometimes I think people hear tgings like this and can’t help themselves, spreading this as true just for the sake of making a comment. It’s like every article that features honey and shows someone dipping a metal spoon into it. People start screaming, “you just deactivated all the enzymes in the honey!” What?????? Stainless steel is non reactive to foods and is food safe. Plus, the equipment to process honey is stainless steel. I will bet 99 percent of these people heard it elsewhere and now consider themselves “experts” and just feel compelled to add their 2 cents.
It is complicated and each situation is different. I have a slightly low magnesium level in my soil but still get frequent magnesium deficiency with yellowing leaves. The leaves go green again after a foliage feed of Magnesium chloride. I use MgCl as it is better ionised than MgSO4/Epsom salts. My problem is very high phosphate levels. Ideal phosphate 25 ppm, my level 963 ppm. Magnesium phosphate is insoluble! So a big problem for me. Even after spreading a ton per acre of Dolomitic limestone (MgCO3). Get a soil test and then you can make an educated choice. My soil is high to very high in NP & K, so a standard NPK fertiliser would be a disaster on my soil. Be careful before you add anything other than compost to your soil.
I am going to buy tons of epsom salt and energetically sprinkle it in my garden. If it is so intelligent as to be able to kill weeds and not plants, then I need it because I am so clueless when it comes to plants etc that I often look at a beautiful flower attached to … a weed or a plant? So, if it dies, then I know it was a weed. If not, I can enjoy the flower.
Releases aluminum from the soil. That is one I am not sure about. Aluminum is not so much a natural thing as it is man-made. It takes a process of heating and chemical separation to get to Alumina before it becomes what we know as aluminum. Its mined from land and sea. what is the precursor to aluminum is already in the water table in many ways.
I think you’re overlooking the effect of magnesium sulfate on PH. All the claims revolve around gardens with high PH soil. If your PH is too high, fertilizer is less effective. Lowering the PH with sulfate leads to less fertilizer needs. If your soil PH is less than 6.5, everything you said is true. If your soil is over 8, like mine is, everything you said is false. So the real answer is: It depends. In this case, it depends on your existing soil PH.
