Saplings, along with apples, are what trees drop once their leaves start to decay (or you destroy them). The type of sapling depends on what tree is decaying. Bone Meal can be used to instantly grow saplings into trees.
- A sapling takes around 4-7 minecraft days to grow, depending on where it's placed and how much light it has. Rain may also cause saplings to grow faster.
- Saplings have a lower chance to drop if you destroy the leaves that contain them.
