Hi, I own a farm and we use Epsom salt for our plants sometimes or at the time of planting because Epsom salt provides the required nutrients to the plant if the soil is nutrient deficient.
As the plant is having all the nutrients from the Epsom salt, we can see a good amount of growth.
For every 500 feet of soil in your garden, add 1/4 th of salt to the water. Either make a drench around the plants, pour the dissolved solution in it, or spray the plants. We can make sure plants get the necessary magnesium by doing this. A nutrient burn can be brought on by using too much Epsom salt. For best results, use Epsom salt every two weeks. Avoid spraying the solution on the plant during the hot summer as this could harm the leaves.
I observed Epsom salt from is of good quality and working effectively for our farm.

An all-purpose dilution rate is one Tablespoon of epsom salts to a gallon of water; this can be used as a foliar spray or as a soil drench. Basically, epsom salts are used as a source of magnesium. Certain plants, including peppers, tomatoes and roses, sometimes benefit from the additional magnesium that is found in epsom salts.
