My thoughts. I will get some small branches going to use as thread grafting material, im going to push for the broom, if it heals over that will be shhhhhweeeeeeet. If it doesn't heal over and rots, imma core it like an apple, slap a peep hole through the front and give this trunk some forced character! I dont have a hollow tree and I love the idea of a broom, but we will see what road this tree decides to go down. So far this tree has been an absolute monster when it comes to growth. Im excited to see where it will be in a few years time!
