What is bone meal?
Bone meal is an organic fertilizer derived from the meat processing industry. Animal bones are cooked, then ground and packaged, and then sold as a slow-release fertilizer that offers a good amount of phosphorous.
The N-P-K (nitrogen-phosphorous-potassium) ratio of bone meal is generally 4-12-0, though some steamed bone meals have N-P-K's of 1-13-0.
Bone meal is frequently used to fertilize spring-blooming bulbs, but it also works well for providing phosphorous in vegetable gardens, on lawns, and in container plantings.
