I have an autumn blaze maple that I planted 4 years ago in my yard. It has a codominant leader. My understanding is that this isn't ideal. I'd like to remove one this year to help it establish one leader. Any advice on which one I should remove? My initial thought was to keep the left side since that is larger, but looking more closely at the split, it looks like maybe I should cut the left and keep the right? Would it be okay to completely remove either all at once? Thanks!
