Fill your tank sprayer with one tablespoon of Epsom Salt per gallon of water. Use this mixture to spray your garden after the initial planting, when the plants start growing and when the vegetables begin to mature.

Since tomatoes are prone to magnesium deficiency, Epsom Salt is a great way to keep the plants healthy later into the season when the leaves of the plant can turn yellow. You may also have noticed a decreased production as the season wanes on.

For tomatoes, it is important to use Epsom Salt at the beginning of the season and all through the season. Add one to two tablespoons of Epsom Salt before sowing seeds or planting a transplant. As the tomato plant matures, work in one tablespoon of Epsom Salt per foot of plant height around the base of the plant. An alternative is to create a spray of one tablespoon of Epsom Salt to a gallon of water and spray the plant every two weeks.
