Origin of Epsom salt

Heptahydrate sulfate mineral epsomite is commonly known as Epsom salt and it gets its name from a bitter saline spring in Epsom, a borough in Surrey, England.

Are Epsom salts better than chemical fertilizers?

Growing plants is indeed an excellent task which most of us like to do but not everyone likes the idea of applying chemicals in the gardens as it may affect the soil quality as well as have a negative impact on the surroundings. Applying synthetic fertilizers exposes the soil and water bodies to dangerous toxins. The hard part is that once the soil is contaminated, it takes years to get rid of toxins and get back to its normal form. It is always better to look for natural alternatives instead of toxic pesticides and fertilizers which can help the plants to grow well without damaging the soil. One such interesting natural alternative which can be used without any hazards is the Epsom salt. They are naturally occurring mineral compounds which can be used as a fertilizer without any after effects. The constituents of Epsom salt (MgSO4-7H2O) are magnesium, sulfur, oxygen and hydrogen. This marvel salt is highly soluble and is effortlessly absorbed by the roots and the leaves. Epsom salt is easy on the pocket, quick acting and easily dissolves in water. So by any means applying Epsom salts is a greener alternative than sticking around with chemicals. I have a lustrous garden filled with juicy tomatoes free of toxins. All credits go to Epsom salts and that shrewd nursery worker.

Why Epsom salts for tomato plants

Tomato plants require sulfur and magnesium for various purposes starting from germination to the blooming phase.  So what does epsom salt do to plants? While sulfur helps to provide essential vitamins, amino acids and enzymes whereas magnesium assists in seed germination, production of chlorophyll, strengthening cell walls and development of healthy fruits. Magnesium also helps in absorbing certain essentials like nitrogen, phosphorus and sulfur. Basically tomato plants can easily get the mineral sulfur but it suffers from magnesium deficiency mostly due to soil depletion. So applying Epsom salts can help sort out this problem. By now you would have understood that Epsom salts can help a great deal in growing healthy tomatoes as it supplies the plants with plenty of sulfur and magnesium.
