Works for all plants, vegetables, and fruits; if you haven't been using, or live under a rock, handfuls of Epsom salt once a month will make your yield explode!!! 2 years ago, 22 maters from one plant, last year (Epsom salt year lol) 112 maters. I've used it on my lawn for years to replenish magnesium back into our sorry Colorado soil, but 2 years ago started using it on all plants inside house and out and the results were dramatic!
I don't know about all this Epsom salt. Most soils are not magnesium deficient, and if yours is, repeated additions will build it back up relatively fast. Too much will unbalance the Ca/Mg ratio which can cause other problems. I would get a soil test at your ag extension service and find out where you're at on pH, minerals and Ca/Mg ratio. I say this to anyone who's adding amendments and hasn't tested their soil, whether it's lime, fertilizers, volcanic rock dust, you name it. If you don't know you need it, you're shooting in the dark. Maybe you just had a good tomato year?
One of the main reasons plants and lawns suffer toward the end of the season is magnesium and nitrogen deficiency's in our area. I've used Epsom salt on my lawn, multiple times a year, for many years. The best part about it is that it doesn't built up in the soil like commercial fertilizers. Good year or not, every vine, veg, or bush I put it on explodes with blooms and grows to freakish heights.
I'm in agreement with Hajidub, epsom salt has made a difference with my tomato plants too. I use pots for mine, so I don't have to worry about soil conditions or other accumulative imbalances from year to year since the soil gets swapped out every year. Just one (of several) advantages pots have over in-ground growing. Anyway, all I know is that I use plenty of bone meal, and now I'm using the epsom salt and things seem to be doing even better for me too. However, in addition to the conversation about this, two nights ago I talked to a biologist friend of mine about why epsom salt works for tomatoes and other plants, so if you please, put your scientist's hats on for a minute here, because this is what he had to say. lol.....
He said MgSO4 is the chemical formula for epsom salt which is mainly composed of magnesium, sulfur and oxygen, with magnesium being extremely important to nearly every organism on the planet. Apparently, the reactivity of magnesium (owing to the availability of electrons in the outermost regions of an Mg atom) makes it an ideal element for a wide array of biochemical reactions. Magnesium is an extremely important plant nutrient, and in fact, at the core of chlorophyll itself is a magnesium atom. In addition to adding magnesium (or epsom salt) to the soil, the addition of calcium is very important too. Calcium is also a very reactive metal which is very important in plant metabolism.
He also mentioned an enzyme (unfortunately, he didn't mention the name of it) that plants use to split water molecules. Water splitting is where this enzyme within plants splits water into its separate components: hydrogen, and oxygen. What does this mean? Essentially, molecules of the chlorophyll pigment are excited by solar energy and donate their electrons to start a flow of energized electrons that play a key role in the process of photosynthesis. The chlorophyll’s donated electrons need to be replaced, and these electrons come from the splitting of water, which is what the enzyme helps to do. In addition, this enzyme also contains calcium which is key to this process. So essentially, calcium is required by the enzyme to aid photosynthesis, and is also a key component of plant metabolization. Not to mention, the production of chlorophyll requires a magnesium atom at its core to exist. So, being that chlorophyll has a magnesium atom at it core, this is again why magnesium plays such an important role in plant growth and production. Given that there are literally billions of chlorophyll molecules in a mature tomato plant, you can see why magnesium is so important for not only a plant to survive, but thrive. Which is why epsom salt tends to work so well because it is mostly composed of magnesium.
So without magnesium and calcium, tomato plants would not be able to create the enzyme that aids photosynthesis, chlorophyll, or plant metabolization. That's why if there is not enough calcium and/or magnesium in the soil for tomato plants they will develop blossom-end rot because the plants are not functioning properly. Furthermore, give them more of these nutrients, and it tends to not only supercharge them, but also keeps them healthier and happier as well. If you haven't tried epsom salt on your tomatoes or other plants, give it a try. Anyway, hopefully all that made sense to you guys. Cheers.
