can you get rid of tomato rot
Excess soil nitrogen causes blossom-end rot, and tomato plants producing green, healthy foliage usually don't require additional nitrogen. Low levels of calcium can cause blossom end rot. Dissolve 4 tablespoons of calcium nitrate in one gallon of water. Place the solution in a spray bottle. Spray the tomato plants with the calcium nitrate when they begin producing new blossoms, applying the solution three times a week throughout fruit formation.
