I had a big box store Kieffer pear top kill a couple years ago. The root stock grew back, it split into 2 leaders, both are about 5' total height and about the diameter of a finger. I t-budded both leaders this past summer at about 3.5' height and appears just one took. Where do I prune this and when? My thought was to prune just above the t-bud that took and leave the other leader on this growing season as a nurse branch. Then next winter prune off the leader with the failed t-bud. Is this a good plan of action?
