Definition: Bone meal is an organic fertlizer that is derived from the meat processing industry. Animal bones are cooked and then ground and packaged, then sold as a slow-release fertilizer that offers a good amount of phosphorous.

The N-P-K ratio of bone meal is generally 4-12-0, though some steamed bone meals have N-P-Ks of 1-13-0.

Bone meal is frequently used to fertilize spring-blooming bulbs, but it also works well in vegetable gardens, on lawns, and in containers to provide phosphorus.

Also Known As: bonemeal, ground bones
Examples:
Each fall, I add bone meal to the planting hole when I plant my spring bulbs.
