Moss Farm
Intermediate Java + Bedrock
Produces: Moss blocks, moss carpet, grass, azalea and flowering azalea (from bonemeal)
Quick answer: Bonemeal on a moss block converts nearby stone, deepslate, tuff and dirt variants into moss in a cornerless 7x11x7 area. Automate it with a stone generator feeding a platform, a dispenser clicking bonemeal, and water or pistons harvesting the moss - bonemeal in, azaleas and moss out.
How it works
- Bone meal on moss spreads it to blocks in the Overworld base-stone and dirt tags (andesite, diorite, granite, tuff, stone, deepslate, dirt...) that have air above.
- The spread area is a cornerless 7x11x7 volume centered on the bonemealed moss block, and only blocks with air above convert.
- Moss can grow grass, azalea or moss carpet on top when generated with air above.
- Each bone meal on a flat 7x7 grid of convertible blocks yields on average about 27 moss blocks (varies widely), worth about 2.5 bone meal in a composter.
- Moss mines fastest with a hoe; a piston breaks it and drops it as an item.
Materials
- At least 1 moss block (lush caves, or trial chambers near slime spawners)
- Dispenser + bonemeal supply (a bone meal farm pairs perfectly)
- Stone generator or dirt supply for conversion blocks
- Observer-clock or lever to fire the dispenser
- Water streams or pistons + hoppers to harvest
Build steps
- Get one moss block from a lush cave (follow an azalea tree on the surface down to the cave below).
- Build a flat 7x11 platform of stone (or dirt) with air above it and a moss block in the center.
- Set a dispenser facing the moss block, filled with bonemeal, on an observer clock.
- Each click converts the platform to moss: harvest with hoes, water streams or piston pushes into hoppers.
- Automate restocking by feeding the platform fresh stone from a generator between clicks.
- Azaleas and flowering azaleas come as byproducts - pot them or compost the surplus.
Rates
Output depends on the design, the version and how much of it you build, so we do not quote an hourly figure. Build the layout below, time it for a few minutes in your own world and scale from there.
Tips
- Moss also marks slime trial spawners in trial chambers.
- A sniffer egg hatches twice as fast on top of moss.
- A moss block in a composter has a 65% chance to raise the level.
- Keep one moss block in reserve before converting the whole platform.
