Underwater Trees

Let your players plant saplings below the surface without weird hacks. Underwater Trees keeps placement safe, auto-replants when you want it, and locks configs down so griefing doesn't spiral out of control.

Why server owners love it

• 🌱 Custom soil + sapling allowlists mean only the trees you approve can grow underwater.
• 🛡️ Stability guard cancels physics + fluid breakage so underwater builds stay intact.
• 💡 Optional light override keeps saplings alive even in deep oceans.
• 🔁 Live reload + config watcher merge new defaults automatically—edit, save, done.
• 🔔 Update checker (Modrinth + Hangar) and join reminders keep your fleet current.
• 🌐 MiniMessage-powered localization lets you style player + console feedback exactly the way you like.

Requirements

• Paper 1.21.x server (Spigot/vanilla forks are not supported).
• Java 21 runtime.
• Optional: a permissions plugin (LuckPerms, etc.) for fine-grained access to /timberella commands.

Setup in 3 steps

1. Drop underwatertrees-paper-<version>.jar into plugins/.
2. Start the server once. config.yml, lang/, and defaults appear under plugins/UnderwaterTrees/.
3. Adjust the config (materials, chat prefix, watcher flags) and run /underwatertrees reload.

From here the async watcher keeps your external edits synced, and reloads also refresh listeners, locales, and update status.

Everyday tips

• Use saplings/soils maps to whitelist exactly what blocks are allowed underwater—unknown materials are ignored safely.
• protect-underwater-saplings shields saplings from physics until your placement rules are broken; leave it on for survival worlds.
• Enable log-detail temporarily to print a full list of active materials and catch typos fast.
• Set update-check.notify-console + update-check.notify-op-join to true so updates are surfaced automatically, and flip update-check.notify-console-always-shown if you still want no-update provider summaries.
• Metrics (metrics-enabled) and update checks (update-check.enabled) are opt-out friendly if your policy requires it.
