how much epsom salts for tomatoes?
Epsom salts (magnesium sulfate) are used to correct a magnesium deficiency in the soil. Before you apply Epsom salts, you should have your soil tested to determine whether there is a magnesium deficiency. If you don't test your soil and your soil isn't deficient in magnesium and you then apply Epsom salts, you could end up with too much magnesium in the soil, which isn't good either. Your soil can be tested through the Jasper County Extension Office.
