Sapling

A sapling is a non-solid block that can be grown into a tree.

Breaking
Saplings can be broken instantly using any tool, including the player's fist, and always drop themselves.

Mangrove propagules can also be broken instantly using any tool, including the player's fist, but only blocks with block states  always drop themselves. When, depending on the age, the chance of drop is different. On, they drop nothing. But on, they have a chance to drop themselves.

Natural generation

 * Spruce

Potted spruce saplings generate in taiga and snowy taiga village mason houses.


 * Birch

Potted birch saplings generate in a room in woodland mansions.


 * Dark oak

58 dark oak saplings generate naturally in a "sapling farm room" in woodland mansions. 28 dark oak saplings are also found inside a chest in that room.


 * Acacia

2 acacia saplings generate in front of each savanna village library.


 * Mangrove propagule

Hanging mangrove propagules generate under leaf blocks of mangrove trees that spawn in mangrove swamps.

Leaves
When leaves decay, or are broken by any tool except shears, they have a 5% chance of dropping a sapling, except for jungle leaves, which have a 2.5% chance of dropping a sapling. The Fortune enchantment increases the rate to 6.25% (2.78% for jungle leaves) at level I, 8.33% (3.125% for jungle leaves) at level II, and 10% (4.17% for jungle leaves) at level III.

Post-generation
Applying bone meal to a block of mangrove leaves with a space underneath produces a hanging mangrove propagule with. At default random tick speed (3), a hanging mangrove propagule adds 1 unit of age every ? game ticks (? seconds). Applying bone meal also increments the age. A mangrove propagule cannot be placed manually below mangrove leaves.

Trading
Each type of sapling is sold by the wandering trader for 5 emeralds.

Growing trees
Saplings come in seven varieties, one for each of the seven trees: oak, birch, spruce, jungle, acacia, dark oak, and mangrove (propagule).

Tree saplings have two growth stages (with no visible difference between them) before growing into trees. When a tree is to be grown, a height is chosen and then the ground and space are checked; if the ground is bad or there is not space for the chosen height, the tree does not grow. Bone meal can be used to speed up the growth of the sapling, even to grow the tree without sufficient light.

Tree saplings can grow into trees when placed on all variants of dirt (except dirt paths) or moss blocks. Additionally, mangrove propagules can be placed on mud. The sapling requires a light level of at least 9, and require a certain volume of space above the sapling, based on its type:


 * Oak needs at least 5 spaces above (3×3 column) to grow normally. If a block is present in the growth space (but not directly above the sapling), the tree still grows, but is forced to grow a large variant.
 * Birch needs at least 6 spaces above (3×3 column).
 * Spruce needs at least 6 spaces above (5×5 column) when placing a single sapling.
 * Giant spruce needs at least 14 spaces above (6x6 column) when planted as 4 saplings in a 2×2 square. Also requires the 4x4 area centered on the saplings at the same level to be empty.
 * Jungle needs at least 5 spaces above (3×3 column) when placing a single sapling.
 * Giant jungle needs at least 11 spaces above (6×6 column) when planted as 4 saplings in a 2×2 square. Also requires the 4x4 area centered on the saplings at the same level to be empty.
 * Acacia needs at least 6 spaces above (5×5 column).
 * Dark oak needs at least 7 spaces above (6×6 column) and must be planted as 4 saplings in a 2×2 square.
 * Mangrove needs at least 6 spaces above the propagule. The height of the tree depends on how far the roots can spread horizontally. The roots can spread up to 5 blocks away from the propagule. It requires at least one solid block within the 9×9×9 cube directly underneath and centered on the sapling outside the column where the sapling is, and solid blocks for the bottoms of the roots to land on within 11 blocks below the sapling in a 9×9 area. The farther the solid blocks are below the sapling, the more attempts it takes to generate a suitable tree shape.

In addition:
 * Saplings can grow only if a player is within a certain radius, even in loaded chunks. For oak saplings, this check applies to individual blocks; for dark oak, acacia and birch, it applies to each chunk.
 * A spruce or jungle sapling cannot grow if it is part of a 2×2 square of saplings that doesn't meet the requirements for a giant tree.
 * Except for giant jungle and giant spruce (as noted above), sapling growth is not affected by nearby blocks on the same level as the sapling(s).
 * A hanging mangrove propagule cannot grow into a tree.

Dirt blocks in the space above the sapling are an exception. Dirt blocks do not stop the sapling from growing. For most tree types, including giant versions, the dirt remains in place and the rest of the tree generates normally around it (it is possible to grow a tree that contains only one log block at the original sapling location, with a column of dirt above where the rest of the trunk should be and leaves spreading out from it). For the large variant of oak trees, the dirt blocks are replaced with log blocks wherever they would normally occur. $$, all types of log block and wood block and their stripped versions are also treated like dirt blocks (they don't stop growth). $$, log and wood blocks are treated like other block types and stop the sapling from growing if they are above it.

When a sapling on a grass block grows into a tree, the grass block becomes a dirt block.

Bee nests
Oak and birch trees grown from saplings that are within 2 blocks of any flower, flowering azalea or flowering azalea leaves have a 5% chance to grow with a bee nest and 1-3 bees in it.

Bees
Bees engage in a pollinating behavior with mangrove propagules, increasing the honey level in beehives and bee nests by 1.

Breeding
Mangrove propagules can be used to breed bees and reduce the remaining growth duration of baby bees by 10%. Bees also follow a player holding a mangrove propagule.

Decoration
Any kind of tree sapling can be placed in a flower pot.

Fuel
Tree saplings can be used as a fuel in furnaces, smelting 0.5 items per sapling.

Composting
Placing a sapling into a composter has a 30% chance of raising the compost level by 1. A stack of saplings yields an average of 2.74 bonemeal.

Trivia

 * If the player stands on the same block as a placed tree sapling, the tree still grows over the player, causing suffocation as it pushes the player out of the block.
