If your plant's leaves are turning yellow, it might have a sulfate deficiency. If your plant's leaves are turning yellow but the veins remain green, it might have a magnesium deficiency. Epsom salts are a great solution for both of these problems.
Make up a solution of about a teaspoon of Epsom salts per litre (quarter gallon) of water in a spray bottle. Simply wet the foliage on your tomato plants every two weeks using a fine spray setting. It will quickly be absorbed by the leaves. Avoid spraying on hot, sunny days or when rain is imminent.
Roses & Epsom Salt
Adding it to plants is said to make foliage greener, healthier and lead to more roses.
Verdict: Unless you have a magnesium deficiency in your garden, there is no need to add Epsom salts. Doing so could even be harmful to soil, plants and water.
If the soil becomes depleted of magnesium, adding Epsom salt will help; and since it poses little danger of overuse like most commercial fertilizers, you can use it safely on nearly all your garden plants.
There are many ways to use Epsom salt on your plants. We suggest using a foliar spray. Substitute a foliar spray in place of a regular watering once or twice a month. Mist your plant leaves lightly with a solution of 2 Tablespoon Epsom salts per gallon of water.
Nitrogen causes stem growth as well as dark green leaf color. Adding only an iron fertilizer or chelate causes the new growth to become green but does not stimulate new growth that much.
Magnesium deficiency
Symptoms: Yellowing between the leaf veins, sometimes with reddish brown tints and early leaf fall.
Epsom salts in the garden are most commonly used as a foliar spray. You simply mix in the required amount of Epsom salt with water and spray it on the leaves of a plant. Ideally, do this in springtime just as new leaves are emerging, and again after blooming.
They are a fast-acting source for magnesium and sulfur. For soils on the alkaline side, the added sulfur is a benefit. Epsom salts, however, do not contain any of the three major components of most fertilizers—nitrogen, phosphorus or potassium—and therefore would not be a complete fertilizer for roses.
Yellowing of the areas between the veins (interveinal chlorosis) is usually indicative of manganese, iron or magnesium deficiency. Iron deficiency affects the youngest leaves first, whereas the symptoms of manganese and magnesium deficiency tend to start in the older leaves.
Magnesium is needed to give leaves their green colour, so when there's a deficiency, yellow breaks through between the veins and around the leaf edges instead. Other colours, such as purple, brown or red, might also appear. Older leaves suffer first, and will die if they're not given any treatment.
Overdose symptoms may include nausea, vomiting, flushing (warmth, redness, or tingly feeling), feeling very hot, slow heart rate, extreme drowsiness, or fainting.
Don't use Epsom salts in a hot tub, whirlpool, or other tub with jets unless the manufacturer says it's OK. Keep the part of your body that hurts in the water for at least 12 minutes. Just relax.
Baking soda on plants causes no apparent harm and may help prevent the bloom of fungal spores in some cases. It is most effective on fruits and vegetables off the vine or stem, but regular applications during the spring can minimize diseases such as powdery mildew and other foliar diseases.
Fertilizing with Epsom salts is a great way to give your plants a boost of magnesium – an element that they need to grow and thrive. 'It is an essential nutrient that helps with photosynthesis and the overall health of the plant,' adds Rodger St.
A yellow leaf has lost its chlorophyll (pigment) and it can't turn green again even after you correct the problem. Don't worry, if the plant regains its health, it's possible that new leaves will fill in during the next growing season. Growing plants is always a matter of patience.

These symptoms together mean that your plant is overwatered. Usually lower leaves drop first, although the whole plant may be affected. The solution = repot (to remove soaked soil) and water less, or let soil dry out and water less.
Epsom salt works wonders as a fertilizer during the growing season and can help keep your succulents looking lush and beautiful for a long while. In addition, using an Epsom salt fertilizer is a great way to help encourage blooming in many succulents.
Epsom salt is very useful for your indoor plants as it encourages nutrient intake. This helps the plant to absorb more from the growing medium, resulting in better growth and green leaves. Use 1 tablespoon in 1 gallon of water and use it on plants once in 3-4 weeks.
Epsom salt is used to relax muscles and relieve pain in the shoulders, neck, back and skull. For example, by relaxing the muscles surrounding your skull, the magnesium in Epsom salt may help release a headache or migraine. This benefit can also aid sore muscles in the recovery period after a workout.
