I get bored of cutting down trees and having to go re-seed the world with acorns. Then I had a brainwave and decided to cut down the tree but leave the stump in place, like so:
So, will these grow back? I did this a little while ago and there appears to be no signs of regrowth (although this is possibly because of the corruption). If that doesn't work, if I cut them a little higher, leaving say 2-3 blocks, will that help instead?
