Bone Meal

Bone meal is a material made from crafting bones. It can be used as dye as well as a fertilizer for most plants.

Fertilizer

 * Seeds, Potatoes, Carrots: The plant will grow 2–5 growth stages.
 * Melon and Pumpkin Seeds: The planted stem will grow 2–5 growth stages. Bone meal only affects the stem itself; it will not cause melons or pumpkins to sprout from a mature stem.
 * Saplings: The sapling has a 45% chance of growing to the next growth stage. Saplings have two growth stages (with no visible difference between them) before growing into trees. A tree will not grow if the sapling is not planted in proper ground or if sufficient space is not available.
 * Grass Blocks: Tall grass, and usually a few flowers, will form on the targeted block and on randomly-selected adjacent grass blocks up to 7 blocks away (taxicab distance). The flowers that appear are dependent on the biome, meaning that in order to obtain specific flowers, the player must travel to biomes where the flowers are found naturally. See flowers for more information.
 * Sunflowers, Lilacs, Rose bushes, and Peonies: The the corresponding item form will drop, without destroying the original plant.
 * Tall Grass and Ferns: A one-block-high tall grass or fern (that is on dirt, grass, or farmland) will grow into a two-block-high tall grass or fern.
 * Mushrooms: Has a 40% chance of growing into a huge mushroom if on dirt, grass, or mycelium.
 * Cocoa: The cocoa plant will grow 1 growth stage.
 * Sugar Canes: On the Pocket Edition only, bone meal grows sugar cane to maximum height (three blocks tall).
 * Flowers: In Pocket Edition, using bone meal on some flowers will make poppies and dandelions grow in the surrounding area.

Bone meal does not work on cacti, vines, nether wart, or other plants not listed above.

Trivia

 * Tall grass planted with bone meal in an area already populated with grass blocks can force grass to appear up to 6 blocks away from where you originally used it. The chance of any plant growing on the block decreases with distance from the block which bone meal was used on, the chance becoming very small at 6 blocks distance.
 * Bone meal can be used on the sides or bottom of a grass block, as well as on a grass block with plants already on top of it.
 * Regardless of if it succeeds in fertilizing, bone meal makes green sparkles. However, like smoke from a torch, the sparkles only appear if the player has particles set All or Decreased.
