Oh The Trees You'll Grow is a shared code library, not a mod players seek out on its own. It lets other mods build custom trees from Minecraft's `.nbt` structure template files instead of writing tree generation from scratch, and Oh The Biomes We've Gone lists it as a required dependency. It ships for Fabric, Forge, NeoForge, and Quilt, and it only needs to sit on the server; a vanilla client can still connect.
What Oh The Trees You'll Grow actually does
The library gives modders a configurable system for defining tree shapes with Minecraft's own structure template format, rather than hand-coding tree generation for every biome mod that wants custom trees. It was originally built for Oh The Biomes You'll Go and now backs that mod's spiritual successor, Oh The Biomes We've Gone. Installed by itself, with nothing that calls into it, it changes nothing in a world; it only lets the mod that requires it load and generate its trees.
Which mods need Oh The Trees You'll Grow
Oh The Biomes We've Gone is the confirmed dependent: its own Modrinth version listings mark Oh The Trees You'll Grow as a required dependency alongside TerraBlender and GeckoLib. If another mod's page or a crash log names Oh The Trees You'll Grow as missing, match this library's loader and version to that mod, not to your Minecraft version alone.
Fixing the missing dependency crash
- 1.Check which mod's dependency list named Oh The Trees You'll Grow, and note its loader and Minecraft version.
- 2.Download the Oh The Trees You'll Grow build for that exact loader and version from the Modrinth project page.
- 3.On Fabric or Quilt, also install Fabric API, since every Fabric and Quilt build declares it as a required dependency.
- 4.Drop the jar into the server's mods folder next to the mod that needed it; the Forge and NeoForge builds declare no further dependencies.
Fabric, Forge, NeoForge, and Quilt version support
Oh The Trees You'll Grow stays even across every loader it ships for. Fabric, Quilt, Forge, and NeoForge all reached build 12.0.0 for Minecraft 26.3 on 2026-09-20, with no loader lagging behind the others the way many multi-loader libraries do.
Questions about Oh The Trees You'll Grow.
5 questions
What does Oh The Trees You'll Grow do?
It is a tree generation library, not a standalone mod. It lets other mods build custom trees from Minecraft's own structure template files instead of coding tree generation themselves. Installed alone, it adds nothing to a world; it only lets a mod that requires it, such as Oh The Biomes We've Gone, load and generate its trees.
Which mods need Oh The Trees You'll Grow?
Oh The Biomes We've Gone is the confirmed dependent, listing it as a required dependency on Modrinth alongside TerraBlender and GeckoLib. Check the mod that prompted the download for its own dependency list, since a missing-dependency error names the mod that needs it, not this library on its own.
Why am I getting a missing dependency error for Oh The Trees You'll Grow?
A mod you installed, most likely Oh The Biomes We've Gone, requires Oh The Trees You'll Grow and it was not found for the matching loader and Minecraft version. Download the build that matches that mod's loader and version, and add Fabric API too if you are on Fabric or Quilt.
Does Oh The Trees You'll Grow work with Fabric, Forge, NeoForge, and Quilt?
Yes. All four loaders reached build 12.0.0 for Minecraft 26.3 on 2026-09-20, with no loader falling behind the others. Fabric and Quilt builds also require Fabric API; Forge and NeoForge builds declare no further dependencies.
Is Oh The Trees You'll Grow safe to install?
It is distributed as source-backed jar files through Modrinth and CurseForge under the Mozilla Public License 2.0, with no bundled installer or extras beyond the shared library code other mods call into. It has no visible effect unless another mod requires it.
