Dead or missing plants

The build pastes correctly, and then plants start disappearing — flowers pop off, saplings break, grass turns to dirt, leaves decay away over the next few minutes. Sometimes the greenery is all there but the wrong colour: grey, brown, or a green that does not match the screenshots.

• Plants check what is under them the moment they get a block update, and break if it is wrong. A flower that arrived on grass but landed on stone removes itself.
• Leaves that are not connected to a log within six blocks decay on their own. Pasting can separate a canopy from its trunk.
• Grass and leaf colour comes from the biome, not from the block. The same build looks lush in a plains biome and dead grey in a desert or a snowy one — nothing is broken, the game is tinting it.
• Light level matters too: plants in an unlit interior break as soon as they are updated.

1. 1For colour, change the biome rather than the blocks. On a server with WorldEdit, select the area and use //setbiome with the biome the build was made for — the map's page or its read-me usually says which.
2. 2For plants that keep breaking, check what they are standing on and fix the ground first.
3. 3For decaying leaves, make sure the trunk came across with the canopy, or replace the leaves with the persistent variant so they stop checking.
4. 4Paste with updates suppressed where your tool supports it — that stops the chain of breaks starting in the first place.
