Hey! The mod description says that this mod works with any tree that grows using bone meal but it appears that the Palm Tree Sapling from Tropicraft doesn't register when using this mods tree growing mechanics. It could be possible that this issue is a problem with the way that Tropicraft has created it's trees or it could be something I'm doing wrong but not sure. Hopefully you can reproduce this. Thanks. :)

Sorry seems it was user error as I tested it lowering cooldown etc and it seems to work now. :)
