Also to know is, how do I stop my saplings from growing?
Just put the block at the height you can reach from the ground (7 air blocks) over the sap. That way it can't grow beyond what you can easily chop. Try placing some String on top, its nearly invisible.
Similarly, what determines tree size Minecraft? Trees vary widely in height, from a bare minimum of 1 block of logs for bush trees, ranging up to a maximum of 30 blocks for giant jungle trees. Tree canopies are composed of leaf blocks and grow 1 block higher than the highest log block (except for that of the giant oak tree, whose leaves grow 3 blocks higher).
One may also ask, how do you restrict oak tree growth?
Placing a block 6 blocks above an Oak Sapling allows it to grow but prevents annoying giant Oaks. It should not remove blocks when growing.
How much of a tree can you cut without killing it?
One wrong cut won't immediately kill your tree, but pruning incorrectly or too often can. If a tree repeatedly loses too much of its canopy at one time, it can become weak or even die from the stress. That's why you shouldn't trim more than 25% of a tree's canopy at one time.
