Sapling

A sapling is an item that can be grown into trees.

Obtaining
Saplings can be broken using any tool, and will always drop itself.

Leaves
When leaves are broken by any tool except shears, they will have a 5% chance of dropping a sapling. Jungle leaves instead have a 2.5% chance of dropping a sapling.

Natural generation
Oak saplings have a chance of spawning in village blacksmith chests.

Usage
Saplings come in six varieties, those being oak, birch, spruce, jungle, acacia, and dark oak.

Fuel
A sapling can be used as fuel in a furnace. It smelts for 5 seconds, or half an operation.

Growing trees
Saplings can grow into trees when placed on dirt, podzol or a grass block. The sapling requires a light level of at least 9, and require a certain amount of space around the sapling, based on it's type:
 * Oak needs at least 5 spaces above
 * Birch needs at least 6 spaces above
 * Spruce needs at least 7 spaces above when placing a single sapling
 * Giant spruce needs at least 16 spaces above when placed in a 2×2 square
 * Jungle needs at least 7 spaces above when placing a single sapling
 * Giant jungle needs at least 13 spaces above when placed in a 2×2 square
 * Acacia needs at least 7 spaces above
 * Dark Oak needs at least 7 spaces above and must be placed in a 2×2 square

Bone meal can be used to speed up the growth of the sapling. It takes 2–4 uses of bone meal to grow a tree. If there is not enough space, the sapling will not grow.

Breaking blocks
Dark oak saplings may grow downwards if there are parts of a previously grown dark oak trees above. When they grow downwards, it will replace any blocks that are in the way including normally unbreakable blocks like bedrock. This mechanic is a little inconsistent, and is likely to be patched in the future.

Data values
A sapling has the ID name  and is further defined by its block data. A sapling also has a block state which is expected to replace the functionality of block data in a future version.

Trivia

 * If the player stands on the same block as a placed sapling, the tree will still grow over the player, which will cause suffocation as it pushed the player out of the block.
 * Saplings can grow without the required amount of light if bone meal is used.
 * Birch Sapling is a mirrored and reversed-colored version of Oak Sapling.
