Natural generation

Moss generates on the floor and ceiling within the lush caves biome. They can also be found in trial chambers indicating that a trial spawner can spawn slimes.

Mob loot

An enderman holding a moss block drops the block upon death.

In Bedrock Edition, wandering traders have a chance of 25% (increased by 1% per level of Looting) to drop 2 moss blocks when killed while showing the item as trade offer, if the player holds an emerald.

Post-generation

When bone meal is used on a moss block, moss spreads to any of the blocks listed below, if they have air blocks immediately above them, in a cornerless 7×11×7 volume centered on the original moss block. Foliage can replace air on any of these blocks.

The following blocks can be replaced with moss blocks:

When a moss block generates with air above it, it has a chance to have grass, an azalea, or a moss carpet growing on it.

Bone meal on moss blocks

Block	Chance
Short Grass	52.08%
Moss Carpet	26.04%
Tall Grass	10.42%
Azalea	7.29%
Flowering Azalea	4.17%

Spreading specifics

In Java Edition, when bone meal is used on a moss block, first the game checks that the block directly above the moss block is air. If successful, maximum X and Z distances are chosen (independently from each other) with a 50% chance of being either 2 or 3. Then, in a rectangular area centered on the moss block restricted to those maximum distances, the game decides independently for each vertical column whether a block is converted to moss. Each corner has a 0% chance to be selected, each edge has a 75% chance, and the rest of the blocks are always selected. If this check succeeds, a scan is started at a y-level one above the moss block to find a block with air above it. If the scan starts in an air block, it searches up to 6 blocks downward. If it starts in a non-air block, it searches up to 4 blocks upward. Both scans stop on the first block with air above it, even if it cannot be converted to moss. The chosen block is converted to moss if possible, and if so (or if it already was a moss block) there is a 60% chance that vegetation generates above it.

Each piece of bone meal used on a flat 7×7 grid of convertible blocks yields on average 27 moss blocks (varies widely), which give about 2.5 bone meal when put through a composter.

In Java Edition, blocks that can be replaced by moss are listed in the moss_replaceable block tag, which includes blocks with the base_stone_overworld, cave_vines and dirt tags. This theoretically also includes blocks such as cave vines and dirt path, which cannot be converted because they do not have a solid top surface aligned with the block grid.​^{[more information needed for Bedrock Edition]}

Usage

All plants can be placed on moss except for cacti. Small dripleaves can be placed on moss blocks even outside of water. Nether fungi can also be placed on moss, while mushrooms can be placed only at light level 12 or below. Mushrooms placed on moss blocks can be grown into huge mushrooms.

Crafting ingredient

Name	Ingredients	Crafting recipe
Moss Carpet	Moss Block	3
Mossy Cobblestone	Cobblestone + Moss Block
Mossy Stone Bricks	Stone Bricks + Moss Block

Composting

Placing a moss block into a composter has a 65% chance of raising the compost level by 1.

Sniffer eggs

A sniffer egg hatches twice as fast as normal when on top of a moss block.

Piston interactivity

Moss blocks are destroyed and dropped as items when pushed by pistons. They do not stick to sticky pistons, slime blocks or honey blocks.
