As you can see, I'm growing an oak tree at bedrock, but I only have the 3x3 x 4 tall room. It's been there for days, not growing.

I may be able to make the room a bit wider, but what do I do to make it grow?? Is the torch placement ok?



This is rather urgent so any help I would appreciate.

Have you ever seen a 3x3 tree before?
The room has to be much bigger try 7x7x9. Somewhere around there might work.

Try a bone.

Room needs to be around 8 tall, and I would suggest using bonemeal if it's in an enclosed space.

You will need to make the room much wider, and some higher as well. Try 5x5x6.

I think the torch may indeed play a role in blocking the trees growth when placed like this.

It's at bedrock, so any higher would be in lava.

Go up to the lava and place torches on the source blocks, then dig upwards above the tree.

Small oak trees are the most commonly encountered, and resemble birch trees in their shape and size. They require no horizontal clearance at the base, 1 block around the main trunk, 2 blocks from the top of the trunk up to the ceiling and 6-8 blocks of vertical clearance. Thus, a small oak tree can grow in a 1 deep hole, but not a 2 deep hole. Just as jungle trees, their growth will not be hindered by wood, leaves, dirt and saplings.


A large oak tree.
Large oak trees are more uncommon, and have a distinct look and different growth requirements. They often have "branches", outgrowths of wood on the sides of the trunk, or even freestanding and surrounded by leaves. They require 4-14 blocks of open space directly above the sapling to grow (Air or Leaves only) but can otherwise be completely enclosed on all sides (which allows for the phenomenon of 'Tree Tubes').

Tough. You will have to go higher. Trees need at least 5 blocks above them to grow.

This is what you do:

The lava flow rate is fairly slow, so you can break a block and place another VERY quickly in the space above it. Repeat process until the room is tall enough.
