Epsom Salt, Tomato, and Pepper Growing

Ripe tomatoesEpsom salt used as a foliar spray or soil additive will help tomato and pepper plants grow and produce larger, tastier yields.

Late in the season use an Epsom salt spray to increase tomato and pepper yield and keep plants green and bushy; early in the season add Epsom salt to the soil to aid germination, early root and cell development, photosynthesis, plant growth, and to prevent blossom-end rot.

Epsom salt is a natural mineral compound of about 10 percent magnesium and about 13 percent sulfur—often referred to as magnesium-sulfate. Epsom salt is highly soluble and easily taken in by plants when combined with water and sprayed on leaves. As a soil additive, Epsom salt becomes soluble with soil moisture and is drawn up into plants through the roots.

A magnesium or sulfur deficiency in the soil can cause tomato and pepper plants to grow small and spindly, leaves to yellow between leaf veins late in the season, and fruit to be slow in maturing and ripening.

How to Apply Epsom Salt to Plants

• Foliar spray during the season. Add two tablespoons (42 grams) of Epsom salt to a gallon (3.8 liters) of water and use a tank sprayer to apply the mix once a month substituting the spray for regular watering. Use one tablespoon (21.25 grams) per gallon of water if you apply Epsom salt spray more often than once a month. Begin foliar spraying when blooms first appear.

• Sidedressing during the season. Work one tablespoon (21.25 grams) of Epsom salt per foot of plant height around the base of each plant. Sidedress plants every six weeks beginning soon after leaves appear and continuing through the end harvest.

• Soil additive at planting time. Add one or two tablespoons (21.25–42 grams) of Epsom salt to the bottom of each hole before planting seeds or transplants.

More useful information about magnesium and sulfur:

  • Magnesium is critical for seed germination, production of chlorophyll, and fruit development; it helps strengthen cell walls and improves plant uptake of nitrogen, phosphorus, and sulfur.
  • Sulfur is critical for the production of vitamins, amino acids and protein, and enzymes.
  • Alkaline soils with a pH of 7 or greater and acidic soils high in calcium and potassium often have low levels of magnesium. Calcium and potassium compete with magnesium for uptake by plant roots—magnesium can be blocked from plant uptake by calcium and potassium.
  • Dolomitic lime which is used to raise the pH of acidic soils is rich in magnesium (46 percent calcium carbonate, 38 percent magnesium carbonate).
  • The soil additive Sul-Po-Mag (22 percent sulfur, 22 percent potassium, 11 percent magnesium) which is often added to alkaline soils should negate the need for Epsom salt.
  • Beans, peas, lettuce, and spinach produce good yields in soil with a low magnesium level.
  • A soil test will tell you if your soil is nutrient deficient. The cooperative extension service in your area or a private soil testing laboratory can perform a soil analysis.
  • Epsom salt is available at the garden center and hardware stores as are most other soil additives.
  • Epsom salt gets its name from the town of Epsom in Surrey, England where the bitter salt was first produced from a saline spring.

    • Me either. I have a small garden. I did try this this year. Wow. It does work. My tomatoes are sweeter and not cracked or split anymore, like previous years. It also is great for green beans. I grow Blulake bush beans. I will use Epsom salt next year in my garden.

    • Michael, you are right but for the few cents it costs to apply for the whole growing season, why spend much more money on a test. The plant will use the magnesium and sulfur that it needs.

      • but how much does that cost? How often do you do it? and I have been container gardening year round along with the garden, wouldn’t it cost a fortune to get that done for a bunch of different containers?

        • Epsom salt is not expensive. You can find it at a local supermarket or drug store. You will only need a pinch or two for each container. Add Epsom salt once a season at planting time.

          • Tom, it’s true that Epsom salt is inexpensive, but the fact remains that not every garden needs additional Mg. And too much of ANY mineral is almost as bad, and sometimes worse, than not having enough. When you consider that an organic tomato sells for more than $5/#, $25 for a comprehensive soil test is not that much to pay for good, quality, mineral rich produce.

          • Epsom salt can be lightly worked into the soil or it can be mixed in water until it soluble then pour the mix around the base of the plant.

        • No – A whole large bag is only a few dollars and you only use a tablespoon mixed in 1/2 gallon of water, or a tablespoon a side dressing. I stumbled upon this hint years ago when my pepper pant didn’t look well – couldn’t believe how it perked up and started to produce peppers. I grow everything in containers as I only have a “patio” back yard.

          • I have a yard and this year decided to do the container garden.. so far so good. But how much salt to put around tomato plants? Can I just sprinkle around the far outer edge? Thank you Gayle!

          • Use about a quarter to one-third tablespoon for a 5-gallon container; sprinkle it on the soil and then gently work it into the soil. It will become soluble with watering.

    • I agree with Michael, There is a great website called gardeningmyths.com where all these old wives tales are tested in controlled experiments. Anytime I get sage advice about gardening I always check it on there. Epson salt is defiantly on it! I don’t know why anyone would dump any kind additive into there garden with out a soil test. My state provides them for free during most of the year through our cooperative extension, but I would still pay for it to know what my soil needed.

  1. This post implies that using Epsom Salt will always benefit tomatoes and peppers, and that is just not the case. IF you need magnesium, the MgSO4 is a great source but if you don’t you could do more harm than good. Test the soil OR test the plant. Do NOT guess.

    • Magnesium deficiencies are quite common in vegetable gardening, and a very inexpensive way to address that issue is by adding inexpensive Epsom salt to the garden’s soil. Epsom salt is a fairly innocuous additive to a garden’s soil. It will either aid a magnesium deficient soil, or it will do nothing in a soil which has adequate amounts of magnesium.

      It’s better to have it in the soil and available for the plant than to not. One would have to apply a ridiculously large amount of Epsom salt to their garden to cause damage to the soil composition or plants.

      • Wrong. Magnesium competes with calcium for uptake into the plant. If your soil is low in calcium adding more magnesium will cause blossom end rot due to lack of calcium. Do a soil test before adding any micronutrient.

    • Epson salts are a cheap, efficient, time honoured, tested, true and natural additive that almost every household has a stash of (usually close to their bathtub). When I’m done tossing some into the soil, I end my day by pouring a bath loaded with it to soak away my own off-kilter lactic acid stressors from all that wonderful gardening. Whatever I don’t soak up, goes down the drain when I pull the plug and I’m out about 3cents…which translates…I don’t need to pay for gas to get to a spa to pay for a treatment to get the results I got for next to nothing at home. Kind of like not digging up soil samples and not paying for gas to not bring to a lab so I don’t have to wait for results that I don’t have the time or money to waste on because I plan on buying more Epson salts with the money I saved not going to a lab:)

      • 10000% Agree! The dollar tree store has epson salts for a buck a bag! a bag lasts a long time-I use epson salts on my aching feet and it helps!

        I used this on my container peppers last summer and they grew HUGE. I also dress the top of pots with 4″ of compost-so I fill the container 2/3 with 50/50 garden soil and compost then dress with compost on top=this gives the plants all the nutrients it needs! I no longer use bagged potting mix=mix has zero nutrients-although it’s good at breaking up clay soils and regular garden soil doesn’t dry out as fast as potting mix.

    • Time to give up on pushing for soil tests. I have had so many soil tests done. By three different labs here in Texas. I use the magnisium sulfate as described here with good results.

    • You can do nothing better for your crops than feeding the soil a well-aged compost–rich in all the nutrients vegetables and fruits require. Concentrate on your soil and your tomatoes and passion fruits will take care of themselves.

      • Compost is really really good but if you have a I Magnesium deficiency No amount of compost is going to fix that. You can’t get magnesium out of compost. i grew up on a farm a real farm my dad farmed several hundred acres I have lived On a farm all my life. I’m not talking about a ranch I’m talking about A ranch I’m talking about row croup farm every thing from peanut corn Soy beans pretty much everything grown In the US but cotton. Post a 5 acre garden we sold produce out of. And we had to add trace generals about ever year. We did do soul test and our farms coop would you a fertile mix for each individual field. Or sections the field of one needed more than the other. So make sure you tell people right before just say compost fixes all evils in a garden because it want.

  2. Are you talking British, or US gallons? Any chance to put liter equivalent in brackets, so we don’t have to guess? Would also save time re-calculating the volumes. Thanks

  3. Hi Steve
    I have been reading many articles about Epsom salt and I have found what you had to say most informative, I then read about your book, I quite like it the USA reviews and the information in the book in Amazon UK. So I bought the book. I have been gardening organically for a while, last year I studied permaculture design with Geoff Lawton.

      • It is 100% true that epsom salt is beneficial. I have always used it prior to reading your post. I love when someone out there validates what I believe. If your not using Epsom salt deficiency or not your not allowing your plants to reap the full benefits it could receive to give You the best harvest you’ll ever have. It’s a no-brain er after you’ve tried it at least once. I spray my foliage twice a month and feed the roots Epsom once a month one table spoon of Epsom salt to a gallon of water once a month. IT WORKS!

          • Soluble magnesium in the soil is drawn up to plant cells via the uptake of soil moisture. Not all vegetables need magnesium (leafy crops don’t need much), but most fruiting vegetables such as peppers, tomatoes, and eggplants for fruit cell development. If the soil magnesium levels are good, there is no need to add additional magnesium to support fruiting crops. Low soil pH, dry soil, and low temperatures can inhibit the uptake of magnesium. Most organic fertilizers for vegetables will have small amounts of magnesium added.

          • Why do you come on someone else’s site and argue the point, over and over- about an issue that, even if u were right, is insignificant BC the treatment seems to be benign enough. Giving your opinion once wasn’t enough? Its not a perfect world done by the book, and its a good general answer to something that’s usually the problem. Were not here to get advice from YOU. Everyone has opinions- and this site has never given me anything but great advice. You could start your own, but I doubt you will come close to the success that this one has had bc they are courteous, knowledgeable, and helpful.

  4. Most of my garden does well except for my lima beans and field peas. Need help there and also for my collie flower which turns black on top. At one time I grew great flowers. Most of my garden seems to come to fruit and doesn’t mature right. My beans and peas the worst. My dirt is a washout some times. I hit it heavy this year with sulfur 8-8-8 seven years ago I was taking the tomatoes out of my garden with the wheel barrel. They made a jungle and produced heavy. Normally I put fish oil bone meal and superphosphate under them. Las year they did not do well at all. My okra, butter nut jalapeno peppers did fare but that was all. I can and am getting short on beans and peas. Gerald

    • Your beans and peas need less nitrogen than you are feeding them– try 3-5-5, or a low nitrogen fertilizer. Improve your soil by adding aged compost to the planting beds twice a year. Spread 1-2 inches of compost across the planting beds in spring and again in late autumn.

      • Cauliflower will turn brown or black because you didn’t take the outer leaves and gather at the top shielding the heads. I did this last year and my cauliflower was beautiful and the largest heads I’ve ever had. Don’t tye to tight near the bottom just on the top leaf area. Good luck and happy gardening.

  5. I would reiterate what Michael LaBelle said earlier: “Adding Epsom Salt to the soil for peppers and tomatoes is only beneficial IF there is a deficiency.”
    Your local state university extension department should have all sorts of information regarding soils in your area of the country, and they’re often the body that can do the soil testing too. The soil test is quite comprehensive and will tell you much about the various components of your soil, and how to remedy an overabundance, or a deficiency, of a particular element. They will also tell you how to collect the soil sample used for the test.
    In Colorado, for example, our soils are often quite alkaline, as well as being deficient in nitrogen and over-supplied with magnesium. The addition of Epsom salt and/or dolomite are NOT recommended here.
    Like Steve says, “concentrate on your soil”.
    It’s the biggest factor in gardening success. Know your soil! All soils are NOT alike.

    • But Penny, don’t put all of Colorado into one category… My soil is alkaline, but has tested deficient in magneseum. In my case, Epsom Salts are helpful. Like you said, testing is important, but Colorado’s a big state… different areas in the state will have different needs, and no one should be told to eliminate a potentially helpful additive.

      • Thank you both Penny and Eric. Every state has multiple soil profiles. Scientists at the University of California, Davis have identified more than 40 different soil profiles in California alone. For the everyday gardener, there is no substitute for aged compost to improve the soil.

    • Steve’s comments about well aged quality compost is spot on. The issue with ANY advice like this is that unless you know what the soil needs just adding something is a guess at best and could actually do more harm than good.

  6. When planting from seeds my tomato’s are spindly we have used just miracle grow they get tall and skinny, also can you use both epson spray sidedress at the same time I live in central ms.

    • There are a couple of reasons tomatoes grow spindly: (1) if they are not growing in direct sunlight, they may be reaching for the sun; move them into direct sunlight; as well, place them where they get some breeze each day–a breeze and moving air will help the stem to grow more stout; (2) the fertilizer you are using may be too rich in nitrogen–use a low nitrogen fertilizer; try an organic 5-10-10.

    • Consult a medical doctor in regards to allergies. “Epsom salt” is the colloquial name for the hydrated chemical Magnesium Sulfate; Epsom salt contains sulfur.

    • Mint and rosemary oil can be used to keep some pest insects away from plants; the strong smell of those oils make many pests turn away.

    • Yes, melons can be sweetened by giving them a dose of Epsom salts and borax. Add about 6 1/2 tablespoons of Epsom salts and 3 1/2 tablespoons of household borax to five gallons of water. Spray the plants when the vines start to run and again when the fruits are between one and two inches in diameter.

    • Yes, but do not over apply any fertilizer or soil amendment. Epsom salts is hydrated magnesium sulfate (about 10 percent magnesium and 13 percent sulfur). Magnesium is critical for seed germination and the production of chlorophyll and it helps strengthen cell walls and improves a plant’s uptake of nitrogen, phosphorus, and sulfur.

    • Thanks for reading Harvest to Table. All of my best advise is right here on the website. Check the Topics Index for subjects you want to know more about.

    • Keep a daily eye out on your plants and you should have success. Keep the soil just moist throughout the growing season–sometimes a moisture meter can help gauge soil moisture in containers. Happy gardening!

    • Allow plants to gain some height, width, and maturity before feeding them Epsom salt. Seed starting or potting soil should have sufficient nutrients to get the seedlings up to about 6 inches tall. The set pot them up to the next size container or set them in the garden. After plants have been in the garden for a few weeks you can give them their first Epsom salt feeding. Then feed plants with compost tea once a week and Epsom salt once a month.

    • Yes, Epsom salts can help roses. Epsom salts are comprised of magnesium sulfate. Magnesium and sulfur are important elements in the soil and are secondary nutrients for plants. Magnesium is necessary for plants to generate chlorophyll, which is important for plant photosynthesis. Magnesium also helps plants absorb phosphorus which is essential for plant growth and blooms. Give roses one-half to three-quarters cup of Epsom salts each spring. Sprinkle the salts in a ring around the perimeter of rose bushes. Mix the Epsom salts into the soil with a hand fork.

  7. I have Blossom End Rot, long story, but tested soil and the ph was way off the chart of 7.5. I did get some stuff that is used on Hydranges for blue to lower the ph. Market people told me the high ph would not allow the plant to use the Calcium so by lowering it would allow the plant to get the calcium. But now I am getting a few to ripen and they taste horrible and bitter. Would Epsom Salt lower the ph and maybe make the fruit sweeter.

    • Epsom salt will not affect soil pH; so it will not lower the pH. The best approach to lowering pH is both short-term and long-term addition of aged compost (or organic commercial planting mix) to the planting bed. Add 3 or 4 inches to the top of the bed and then turn it under. Do this at least twice a year; in about a year’s time the soil pH should drop on its own. In the short term, do the above, then plant in a raised bed or a mounded bed of commercial planting mix. The bitter flavor will abate once the soil is less alkaline.

  8. Actually, magnesium sulfate (MgSO4) is a salt of magnesium. In chemistry, a salt is chemical compound that results from the reaction of an acid with a base. In this case, sulfuric acid (H2SO4) and magnesium hydroxide (Mg(OH)2). In the reaction is as follows:

    H2SO4+Mg(OH)2 = MgSO4 + 2(H20)

    Salts can be found in nature or can be made in a laboratory. In this case, the source of the sulfuric acid is sulfur dioxide in the air which has combined with water to form sulfuric acid. It’s the same process that tarnishes silver. The problem is that people assume that salt means table salt. Sodium chloride. But there are many different kinds of salt with all different properties.

    • Yes. The garden is never the same from year to year and there is always something new to learn. Thanks for reading Harvest to Table.

  9. I added one tablespoon of epsom salts to every plant one year to my tomato plants. Almost every tomato in the field developed blossom End Rot. Problem is that calcium competes with magnesium for uptake. So with all that magnesium in the soil, the plant could not uptake the calcium it needed and BER was the result. Now I add one Tums for calcium and there is no longer a problem with BER.

    So if your soil is low in magnesium epsom salts will help. If your soil is low in calcium adding Tums will help. Do not add these micronutrients without a soil test first.

  10. I have a cherry tomato plant in a container. It wasn’t growing so I sprinkled a tablespoon of es around the soil and within 2 weeks it began having new growth and flowers so now I’m wondering how often I should apply the es and how much?

    • You can give your plants a light Epsom salts boost once a month or so; a tablespoon is more than enough and water it in. You won’t need to add more once the season is half over.

  11. Epsom salt is a salt. When an acid reacts with a base, the reaction products are water molecules and salts. NaCl is one of the infinite possibilities for this larger definition of the word “salt.” for example 1 H2S (sulfuric acid) + 1 Mg(OH)2 (milk of magnesia) = 2 HOH (water) + 1 MgS (epsom salt). NaCl is the salt produced by the reaction of hydrochloric acid (HCl) and lye (NaOH).

  12. Epsom salt, or Magnesium Sulfate (MgSO4) actually is a salt. It consists of two ions. It has the positively charged magnesium ion and the negatively charged sulfate ion, bound into a crystal with strong ionic bonds. Water, being a highly polar molecule, aggressively rips these two species apart from each other, the magnesium grabbed by oxygen, the sulfate grabbed by hydrogen and pulled apart. Ionic compounds are defined as salts. Usually there is a metallic positive ion, just as in table salt has sodium as it’s metallic component, epsom salt has magnesium. Anyway, the bottom line is that epsom salt is in fact a salt.

  13. I have an issue with squash… they all seem to get blossum end rot and will rot even when very small. I did a soil test -pH- 6.5-6.8 very low in potash and potassium. Tomatoes usually do well although have had issues with BER with Krim tomatoes. I have a compost tumbler-style of composter and will dump the contents in October or so. The soil used to be poor in texture but noe is essily “workable”. I don’t have issues with other vegetables (beans, Swiss chard, lettuce, kale, radishes, spinach) it’s primarily squash (ih, peppers do NOT do well hete either) so I’m not sure what to add or do si that squash will grow. Even zucchini rots… and that’s saying something! Would Epsom salts help??
    I will appreciate any suggestions! (I predominately love my winter squash- Hubbard, butternut, and acorn).
    Thank you!

    • Add a tablespoon or two of epsom salt or dolomitic limestone to the planting hole when transplanting, or sidedress around plants with epsom salt or dolomitic limestone. Epsom salt contains magnesium which aids early root and cell development and plant growth which in turn will slow to stop blossom end rot. Keep the soil evenly moist so that plant roots can draw up magnesium and calcium from the soil.

  14. I live in Arizona, I have both pepper plants and tomato plants. The paper plants are growing very slow and not flowering. My tomato plants are growing but have a few flowers not produce, I would like to try the es but not sure how much to use. Also I water every day am I possibly watering to much,? Could that be the reason they are not flowering? Any help is greatly appreciated. This is what all I’m growing in my raised bed garden, regular tomatoes, Roma tomato, cherry tomato, red bell peppers, green bell peppers, jalapeno, cilantro, green onion. They all seem to need some help. I do use miracle grow fertilizer. Can you use regular es from like the bath area or does it come from the garden section? Sorry for all the questions I’m new at this whole garden thing in Arizona I came from Oregon I didnt have any issues there. Thank you in advance for you advice.

    • Hold off on Epsom salts for now. The plants are stressed. If the plants are taller than 8 inches, they do not need water every day; get a moisture meter and check the moisture at 8 inches deep; water accordingly. Get a 5-10-10 fertilizer such as Lily Miller Mor-Crop (which also contains calcium and magnesium) and give the plants half of the recommended dose for the next month. If the plant gains strength then give it a full dose after a month–follow the directions, but use half as much as recommended until the plants flower and set fruit.

  15. Epsom salt is OMRI approved so it can be used in your organic garden if your soil is magnesium deficient. I always soil test before planting and once during the season. Every few years a test is sent to the local cooperative office and gives me a full analysis of my soil including its composition. Twice a season I test it myself with a kit. This tells me what my plants have depleted from the soil during the growing season and I know what needs to be amended for the fall crops. 20 bucks for a home test kit that gives me 40 tests and tells me my ph and n, p k. is more than worth the money. I use epsom usually only when the plant tells me it needs it and it works well for me.

  16. How i can use the Foliar spray during the season for grape tree and what is the method of applies that.what is the best treatment for Bunch Stem Necrosis in grape during middle of season .pleas advice me.

  17. Hello
    I planted my tomatoes in early June. Usually I plant in late April but we’ve had a cold spring and I wasn’t really sure if covid-19 would have any negative effect on the plants. I planted early girls, big boys, cherry and dwarf Roma. I trim the suckers regularly and water every 3rd day. Once a month I add eggshell which the plants love. They are healthy, flowering well,and producing fruits but only the cherry fruits are ripening. Will E.S. help with ripening? It is now the middle of July. Thank you.

    • It sounds like your larger tomato varieties are on schedule to ripen in mid to late August. It is expected that the cherry tomatoes would ripen first. Epsom salt will not ripen the tomatoes quicker. Keep the plants happy with a feeding of a dilute solution of fish emulsion or kelp meal every 10 days with watering. Check the days to maturity for each variety–you will find that they are due to ripen in August.

  18. First, it’s so great that you take the time (even if repeating is sometimes needed) to answer every question. For me, this is the first time I’ve ever planted a tomato plant. Cherry tomatoes. I do have them (only 2 on my patio) in pots. In the beginning, they grew like crazy and were beautiful and seemingly perfect. Then all of a sudden the bottom portion of the leaves began turning golden brown. Not soft and yellow, like over-watering might suggest, And not crispy dry ones either. Also not the curling leaf thing that I’ve read about. It’s very odd. With every new growth (that still looks great), right below it, the leaves do the same thing. It’s done this from the beginning. So, I trim off the bad ones almost on daily basis. So, now it’s just naked almost all the way to the top. They’re about 5-6 feet tall. They’re still producing pretty good, but beginning not to ripen as well. And now also beginning to have some smaller (grape/large pea sz) fruit. I’ve wondered if it is coming to the end of its life span. IDK I did use miracle grow when I first potted them and have used it, maybe twice since then. My farmer’s daughter DIL said she’d never seen anything like it before. Does this make any sense to you ? Can you offer any suggestions ? Thanks in advance for any help.

    • It is not unusual for the lower, older leaves to die. Leaves can readily fail if they do not get plenty of sunlight or air circulation; make sure the plants are not crowded. At 5 to 6 feet tall, the plants are at or very near maturity. Pinch away the growth tips at the top of the plant and also growth tips on side branches. This will allow the plant to concentrate it energy on producing flowers and maturing fruit already on the plant. Removing excess flowers will allow the plant to increase the size of the fruit on the plant–but will end production as well. If you have 12 or more weeks of warm weather left in the season; you can clip some a few sections of new growth and root them to create new plants/clones which can go on to produce more fruit. If you suspect the curling leaves are related to insects or disease, spray the affected leaves with Neem oil late in the day when the sun is not intense.

  19. Can epsom salt and rock phosphate also be used for cucumber, egg plant, beans, other ethnic asian beans, carrots, and all other home gardening fruits and vegetables ?

  20. Thanks Steve for all the info. I have been growing tomatoes for 45 yrs; but never heard of adding Epsom salt, I’ll try it because we have BER a lot. We live in what used to be a river bed and have had to add planter mix almost every year to our raised beds (the soil is too rocky to dig in). In the past, I’ve always used B1 when transplanting them to help with the root growth. It will be interesting to see how well they do this year with the Ep, so I’ll let you know at the end of summer.

  21. Yes, adding Epsom salt to the soil (or spraying the leaves) will make your tomatoes taste sweeter. Dissolve about a tablespoon of Epsom salt in a a gallon of water and then water around each of the plants or you can foliar spray the plants. This will add magnesium to the soil and improve the plants’ overall health–and yield and flavor. For best flavor, let the tomatoes ripen on the vine, do not pick them too early.

  22. There are many reasons the leaves of squash plants turn yellow, usually environmental: (1) weather too hot; (2) not enough moisture in the soil–keep the soil evenly moist; (3) soil not well-drained, add plenty of compost around each plant to keep natural nutrients optimal. Disease can also cause leaves to yellow; fungal diseases can infect squash plants and lead to plant failure–often this is the result of soil that is not well drained.

  23. hi, grateful to dropby harvest to table..got so much idea about epsom salt…is it ok to foliar spray to eggolants, pechay and other vegies? i have peppers and tomatoes but their leaves are yellowish…can epsom salt help? thanks for the advice,, more power to you..

  24. Yes, you can foliar spray Epsom salt solution. You may want to begin feeding the plants with a dilute solution of fish emulsion or seaweed/kelp meal solution every 10 days; that should give the plants a boost.
