Magnesium sulphate is beneficial in many ways. 1. Prevent transplant shock by sprinkling 1 teaspoon around your newly transplanted plant and water well. Also helps with the germination of seeds. 2. Yellow leaves indicate a magnesium deficiency in the soil so add 1 Tablespoon for every 30 cm of plant height and do this once a month. 3. Remove a tree stump by drilling holes in the stump and filling them with Epsom Salts and it will slowly start breaking down the stump. 4. Leaf Curl is another sign of deficiency in the soil.
