A soil test is always a good idea before adding any amendments to soil. (Except good clean compost.)

I hope that helps.

I have no idea why so many folks want to use Epsom Salts, magnesium sulfate, unless they do know that their soil is deficient in MG++.

Mg++ is also the central part of the chlorophyll molecule, but few are the soils that are Mg++ deficient.

Years ago I know that some of the cities in FL, for instance, used to spray their Palm trees with Epsom salts to green them up before the tourists arrived for the winter. ( smile)

Some will claim it has other benefits but none of them has been research-documented. But yes, if you choose to use it then it needs to be used with some care. Not truly a "salt" but it can have similar effects when used in excess. The commonly seen recommendation for it is 1 T per gallon used as a root drench.

Plants such as tomatoes, peppers, and roses need high levels of magnesium for optimal growth. However, plants may not show the effects of magnesium deficiency until it's severe. Magnesium tends to be lacking in old, weathered soils with low pH, notably in the Southeast and Pacific Northwest.

Sulfur, a key element in plant growth, is critical to production of vitamins, amino acids (therefore protein), and enzymes.

Its proven that plants can absorb salts via foliar application (leaves/stems) which is why Weed Killers like Roundup work. My opinion is that Epsom salts when used as a foliar spray make these elements readily available to the plants.

I find adding Epsom Salts at least twice a season to boost yields. I use 2 tbsp per 2 gallon of water in a watering can and drench the leaves, stems and roots. Whether to believe it or not and use it is up to you. This is what makes gardening fun is that you should do what works for you and it doesn't hurt to try! Good luck!!
