Tree and bone meal farm

Shulkercraft's build of Dusty Dude's four wood tree farm with a moss bone meal farm bolted on, so it never runs out. The tree half is the same slime and honey design already in the library; the new part is the bone meal supply, which is a bilibili design and answers the one question Dusty Dude's video leaves open. Two separate builds joined at the chests, roughly 35 minutes of tutorial, and Shulkercraft credits both designers in the description.

• Chunkload the bone meal farm or switch it off when you leave. Otherwise it starts producing cobblestone instead and the whole thing stops. Building everything inside one chunk avoids it.
• If the TNT barely breaks the top row of logs and blows up the drops on the way out, move the obsidian up one block.
• If the TNT lights as you place the wall, the minecart and rail must face into the slime block and piston, and the TNT goes in before them.
• Spruce saplings not growing is a repeater problem on the back side of the tree farm.
• After 20 to 30 minutes the sand in the bone meal farm drops as an item. Replace it with any block.
• On servers the moss can clump and fall into one composter, which slows bone meal badly. One builder just attached a second bone meal farm to the same chests.
