N : P : K – 3 : 14 : 0 Contains phosphorus, calcium, nitrogen, essential minerals and trace elements. Bone meal is high in phosphorus and has the ability to help your plants, flowers, and fruits stay healthy. Ex: If you feed your tomato plants more phosphorus, their fruit will be larger and more nutritious. The calcium and phosphorus in bone meal will prevent fragile tomato plants from withering after the flower has been cut, allowing you to enjoy the fruits of your own tomato plants. If you want to give your tomato plants more fertilizer but prefer to feed them on an occasional basis rather than on a regular basis, bone meal is a great option.
