Minecraft wiki entry for The_second_day, associated text: Wood is plentiful in forests. If trees are scarce around you, you may want to plant some replacement trees: You may have noticed when you chopped down trees, that as the leaves decay, some of them drop saplings, which you hopefully picked up. You can plant them on any dirt or grass block where there's room for the tree to grow. Once you plant them, don't hang around waiting, just go do other things and come back later when the trees have grown (it can take up to a day or more). Once you have spare torches, you can put one of those a couple or few blocks away from your saplings, as this helps them continue growing overnight.
