A '''moss block''' is a natural block that can be spread to some other blocks by using [[bone meal]].

== Obtaining ==
[[File:Moss block range.png|thumb|Farthest range moss spreads from a central moss block in Java Edition. In Bedrock Edition, the source block would be a few blocks above the center.]]

=== Natural generation ===
Moss generates on the floor and ceiling within the [[lush caves]] biome.

=== Trading ===
Moss blocks can be obtained by [[trading]] with a [[Wandering Trader|wandering trader]], who may sell 2 moss blocks for 1 [[emerald]].

=== Breaking ===
Moss blocks can be mined using any tool or by hand, but a [[hoe]] is the fastest way to break it.

=== Chest loot ===
{{LootChestItem|moss-block}}

=== Post–generation ===
{{IN|java}}, using [[bone meal]] on a moss block causes nearby blocks with the <code>base_stone_overworld</code>, <code>cave_vines</code> and <code>dirt</code> [[tag|tags]] to be converted to moss blocks.{{More info needed|bedrock=behavior in bedrock needs clarification}} 

Moss spreads to any blocks with 2 [[air]] blocks above them in a corner-less 7×11×7 volume centered on the original moss block in Java Edition, and centered a few blocks below the original moss block in Bedrock Edition. Foliage can replace air on any of these blocks.

== Behavior ==
{{IN|java}}, all plants can be placed on moss except for [[cactus]]. [[Fungus|Nether fungi]] can also be placed on moss, but [[mushroom]]s can be placed only at light level 12 or below. {{IN|bedrock}}, cactus, [[bamboo]], [[dead bush]], and [[sugar cane]] are the only plants that ''cannot'' be placed on moss.

Using [[bone meal]] on moss blocks causes certain types of adjacent blocks to be replaced with moss blocks. To allow moss to spread to them, blocks need to have [[air]] above.

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.

=== Spreading specifics ===
{{IN|java}}, when bone meal is used on a moss block, first it is checked 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 by those maximum distances, it is decided independently for each vertical column whether a block is converted to moss. This chance is 0% for the corners of the chosen area, 75% for the edges and 100% for the other columns. 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 up to 4 blocks upward. Both scans stop on the first block with air above it, even if it can not be converted to moss. The chosen block is converted to moss if it can be, and if it can (or already was a moss block) there is a 60% chance vegetation generates above it.

So for every bonemeal that is used, you get on average 27 moss blocks (varies widely though), which gives about 2.5 bonemeal when put through a composter.

=== Piston interactivity ===
Moss blocks are destroyed and dropped as [[item (entity)|items]] when pushed by [[piston]]s. They do not stick to sticky pistons, [[slime block]]s or [[honey block]]s.

==Usage==
=== Crafting ingredient ===
{{crafting usage}}

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

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