About this Mod

About

Allows you to regrow custom trees from Terralith and Blooming Biosphere by using vanilla saplings placed in a custom biome. The sapling used for that custom tree is based on the leaves/log of the custom tree you are growing. White effect particles when placed indicate that you have placed a custom tree.

Growing Vanilla Trees: Crouch/Sneak while placing a sapling in a custom biome to make it grow into a vanilla tree rather than a custom one.
