2 tbsp of epsom per 1 gallon of water 
Alternatively, mix 1 tablespoon Epsom salts with 1 gallon water, and spray onto the plant. This solution can be applied twice in a month, or the Epsom salts can be increased to 2 tablespoons and applied once a month. Apply late in the growing seasonAs the tomatoes grow and produce fruit, magnesium in the soil can wane. So for a 4-foot-tall shrub you would mix 4 tablespoons of Epsom salt to 1 gallon of water. At the beginning of the growing season, spray rose bushes after leaves have opened and before flowering. Spray again after shrubs have flowered. Hi, I have joined this community today. A week back, I sprayed mixture of water and epsom salt through a spray tank having a ratio of 2 tbsp of epsom per 1 gallon of water on a lawn measuring 3000 sqft. A total of 3 gallons of the mixture was sprayed. Rating Newest Oldest. Best Answer: I always put epsom salt in the hole where I plant the tomato plant at the beginning of the growing season and add water to the hole. I usually add 1 tablespoon per plant to about a half gallon water. I only do this once a year. Mix 8 cups of hot water and 1 cup of Epsom salt in a large mixing bowl. You can increase the amounts to fit your specific needs, but be sure to keep the ratio of 1 part Epsom salt to 8 cups water. I have joined this community today.
