Tomato and Peppers
Magnesium deficiency in the soil may be one reason your tomato leaves yellow between the leaf veins late in the season and fruit production slows down. Test your soil every 3 years or so to check on nutrient levels. Epsom salts can keep plants greener and bushier, enhance production of healthier fruit later in the season, and potentially help reduce blossom-end rot. Apply 1 tablespoon of granules around each transplant, or spray a solution of 1 tablespoon Epsom salts per gallon of water at transplanting, first flowering, and fruit set.
Epsom salts are available in drug and grocery stores. Epsom salts work best on soils that are...
Slightly deficient in magnesium
Alkaline (show high pH) as in western areas
Old, "weathered," and acidic (with low pH) soils of the Southeast and Pacific Northwest
High in calcium and potassium (western soils)
