The bug
Most saplings (acacia, both azaleas, birch, spruce, jungle saplings) cannot grow if there is a block diagonally above it. This does not mangrove propagules (sometimes) or any type of mushroom/fungus. In the case of oak saplings, this prevents small oak trees from generating, but not big oak trees.
The growth is also only (generally) prevented by blocks that have a collision box, but it does affect buttons, light blocks, planks, twisting vines and even flowers for some reason. It does not affect the following blocks (list might be incomplete):
- Tall grass
- Glow lichen
- Logs
- Vines (sometimes; see MC-193318, affects certain trees)
- Wood
