So I'm playing on some server, called SkyBlock. It starts with one tree. the first one dropped one sapling, now that I've planted it and accomplished a whole lot of other stuff, I don't want to cut down the second without having at least one sapling come off of it.
So what I'm asking is, can a tree with all the leaves cut off regrow it's leaves? Can I use bonemeal on a tree stump to make it grow back into a tree?
