If the initial position is not air, root system fails to place. Root system checks every position, starting from the initial position and moving upward by Template:Nbt blocks. If it goes above the WORLD_SURFACE heightmap, root system fails to place.

At each position in order:

1. If the amount of air and water blocks above the position is less than Template:Nbt or the highest water block is higher than Template:Nbt, the position is not valid;
2. Template:Nbt Minecraft:block predicate;
3. If Template:Nbt is not 0, in each cardinal direction with an offset Template:Nbt by XZ 2 points are checked with offset Template:Nbt by Y above and below. If below point is air or above point is not air, the position is not valid. That means if Template:Nbt is set to 0, this check will always fail;
4. If below block is lava or not solid, the position is not valid;
5. If Template:NbtTemplate:Nbt fails to place, the position is not valid.

After a position is found, roots are placed within a Template:Nbt along XZ Template:Nbt times. They can replace only Template:NbtTemplate:Nbt blocks. After roots are placed, hanging roots are placed within a radius, defined by Template:Nbt along XZ and Template:Nbt along Y Template:Nbt times. If a block is air, then Minecraft:block predicates has_sturdy_face above and would_survive are applied.
