My redbud tree was snapped off during a storm earlier in the summer. The remaining stump is about 3 feet tall and has sprouted numerous shoots.
Yes, I think you may prune some of the shoots in the late winter to begin to establish a central leader if that's possible. As the tree grows, select strong saddle-shaped forks to keep as part of the main structure of the tree. When most of the tree canopy reaches above head height, prune lower limbs back. This may take a while, but you may want to try to do this instead of removing the damaged tree and replanting. Good luck.
