Tomatogain granular plant food is formulated to provide immediately available nutrients, promote vigorous growth, and high yields while preventing blossom-end rot and splitting. Works well on all vegetables and some fruits, such as but not limited to: tomatoes, peppers, eggplant, cucumbers, melons and strawberries.
