Hi-Yield 'Calcium Nitrate' (4 lbs.) 15.5-0-0
Helps Prevent Blossom End Rot in Tomatoes
It contains two important nutrients that plants need: Calcium (Ca) and Nitrogen (N).
Hi-Yield Calcium Nitrate is used primarily in vegetable gardens, particularly for Tomatoes and Peppers, in the prevention of Blossom End Rot. Blossom End Rot is a common problem with tomatoes.
It is a physiological disorder (not a disease) caused by a lack of calcium. When fruits are enlarging rapidly, sufficient amounts of calcium fail to reach the end of the fruit resulting in a deficiency of calcium in the developing fruit.
Use as a Soil (Side Dress) Application or as a Foliar Spray.
Blossom End Rot begins as a small, water-soaked spot. The spot develops into a dark brown, leathery area on the bottom end of the fruit. The surface of the spot shrinks and becomes flattened or sunken.
