How To Grow Tree Minecraft. Most trees in minecraft will not grow when there is a block next to them. Put the bonemeal in your hotbar, and use your interaction key on the sapling;
Focusing only on the growth portion of the farm, these designs allow you to quickly grow hundreds of trees by pressing down a mouse button and then ignoring it. Even with bone meal it takes a loooong time for it to try to grow a tree small enough for the trunk to fit. When it grows up, chop the tree down and use the newly formed podzol to plant a mushroom and bone meal it up.
