2 × 2 trees only check if northwestern-most sapling has a valid block below it
The bug
When a 2 × 2 tree tries to grow it only tests if the block below the northwestern-most (-Z and -X) sapling is valid. This can cause other problems because when a tree grows it replaces all non-dirt blocks with dirt.
Note: This affects in theory oak trees as well because code-wise they can grow as 2 × 2 variant.
How to reproduce
- Place at -X, -Z and +X, +Z dirt
- Place at +X, -Z and -X, +Z for example stone
- Place the saplings on the dirt
- Use /setblock to place saplings on the stone
- Use bone meal on the -X, -Z sapling
→ You will see that the tree has grown

Dark oak trees will generate with missing layers if certain blocks (ex: dirt, and vines) are above the north-west sapling in the 2x2 grid for growing the dark oak tree.
Steps to Reproduce:
- Replicate the shown setup:
(The vines need to be above the north-west sapling)
- Place dark oak saplings on top of the grass
- Bone meal the saplings
Observed & Expected Behavior:
The dark oak tree grows with a missing 'layer' at the y coordinate of the vine.
The tree would grow as normal, replacing the vine block/s.
Screenshots/Videos:
Notes:
- This issue was originally was part of MC-193318, but I opted to seperate it due to the behavior being inherently different in nature (pun intended). The dark oak tree is not prevented from growing due to the vines, it instead does not grow as would be expected.
- Related to these issues: MC-193318 MC-125481 MC-112975
- This issue was triaged originally as this being reproduable with vines, but is actually possible with more blocks than only vines.
Can confirm in 20w49a.
