To make sure the leader would develop into a strong, upright-growing trunk, I needed to prune off all the side branches in this portion of the tree.
In pruning the top of this tree, I removed both the 2016 and 2017 crow's feet (photo at left). Suddenly, I've reclaimed a single central leader.
My biggest problem in making these pruning cuts is that I needed my 8 foot orchard ladder for every cut. I guess that is the price I pay for grafting onto a fairly large rootstock tree and witnessing 5-7 feet of new growth each year.
