As you already understood from the brief introduction, with this add-on, most plants will be able to plant automatically. Namely these plants:
Plants can only be automatically planted on the block on which they can grow. Also, if something is already growing on this block, then item will not be planted and will remain. That is, item is planted only if there is air above the block on which the item lies. Also, if a stack of items is lying on the ground, then only one seedling will be planted on the block on which the stack was lying and the remaining 63 will be lost. This cannot be fixed in any way yet.
How it works:
This addon only works on versions 1.14 to 1.17 and up. If your version of minecraft is lower (1.13 1.10 1.8) this addon will not work!
This addon does not require any experimental options to be enabled!
This addon works great in multiplayer!
This addon is absolutely compatible with all other addons!
