Leaves Be Gone — a mod for instant and fast leaf decay after cutting down trees in Minecraft

Leaves Be Gone accelerates leaf decay after cutting tree logs in Minecraft. The vanilla game removes the disconnected crown gradually — the process takes up to a minute and involves a series of checks for each block. The mod reduces this time to approximately one second and parallelly reduces server load during mass logging.

How accelerated decay works

After cutting the last log, the mod marks the adjacent leaves for decay and assigns each block a random delay within two values from the config. By default, this is an interval of 5–20 ticks (0.25–1 second). The random delay is designed so that blocks do not disappear simultaneously but in a cascade — this looks more natural and distributes computations across several game ticks instead of one spike.

The exact moment of decay is scheduled via Minecraft's standard delayed tick mechanism — the same one used for plant growth, fire spread, or other timers in the game. Thanks to this, if you exit the world right after chopping a tree and log back in, the leaves will continue to disappear from the point where the timer stopped. No additional checks are performed when reloading a chunk.

Leaf decay after cutting the last log — the crown disappears block by block over a second. 

Support for mods with custom trees

Any mod that registers its leaves under the tag minecraft:leaves, receives accelerated decay automatically — without additional settings. This covers most mods adding new biomes and tree species, even if their leaves are implemented as a separate block, and not as a sub-type of vanilla ones.

A separate config parameter enables decay of leaves not tied to a log of their own kind. In vanilla, for example, oak leaves disappear only next to an oak log — next to birch they survive as usual. This parameter removes such a link for accelerated decay.

Configuration

The file leavesbegone-server.toml is located in the folder .minecraft/config.

Conclusion

Leaves Be Gone removes the slow vanilla disappearance of leaves after chopping. Unlike simpler alternatives for fast leaf decay, which add separate checks for each chopped block or completely replace the leaf class, this mod integrates into the existing game tick without extra iterations — hence less impact on TPS on servers with active logging. Suitable for survival servers where players regularly cut down forests for building, as well as for modpacks with complex biome systems and dozens of tree species.
