Moss Block

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

Natural generation
Moss generates on the floor and ceiling within the lush caves biome and as loot in shipwreck chests.

Using bone meal on a moss block causes nearby stone and dirt type blocks to be converted to moss blocks. Moss spreads to any blocks with air above them in a corner-less 7×11×7 volume centered on the original moss block. Foliage can replace air on any of these blocks. Moss will not replace farmland or infested blocks.

Trading
Moss blocks can be obtained by trading with a 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.

Behavior
In Java Edition, all plants can be placed on moss except for cactus. In Bedrock Edition, cactus, bamboo, dead bush, and sugar cane are the only plants which cannot be placed on moss.

Using bone meal on moss blocks causes grass, moss carpets, azaleas and flowering azaleas to grow.

This has the added effect of replacing adjacent blocks by moss blocks.

Piston interactivity
A moss block drops as an item when a piston pushes it.

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