Tomatoes and epsom salts

Did you know tomato plants like salty soils? In other parts of the country with acidic soils, Epsom Salt water produce bigger blooms and healthier tomato plants. Magnesium Sulfate helps the plant absorb phosphate fertilizers and increases the plants natural resistance to disease.

Since Colorado soils are loaded with calcium and magnesium, you should only use 1-2 tablespoons of Epsom Salt per gallon of water. Apply around the tomato plant only once during the growing season.

Always consult a soil test before adding fertilizers. If your soil is already too salty, adding salt water could contribute to a decline in vegetable production (credit anna). We recommend a soil test from the Colorado State University’s soil testing lab.
