Hi Jeremy. One thing I have learned about pruning questions over the years is that
the answer will depend upon whom you ask and what you're trying to accomplish with your tree. So this is what I would do if this nice little Winecrisp was my tree in my location (maritime pacific NW USA).
My reading of
Fukuoka has
led me to believe that he was talking about no prune methods for non-grafted trees. Once a fruit tree is grafted on to a specific rootstock it basically becomes a "pruned tree" at that point. My feeling is that this being the case, you may as well make peace with pruning the tree thereafter. It doesn't necessarily have to be a lot of pruning but in most cases at least some pruning will be required to maintain health and production of the tree.
We have a small hobby orchard of about 60 fruit trees. My winter and spring climate is very wet and I learned that the traditional time of year to prune fruit trees (late winter/early spring) is asking for disease trouble. Some years ago I stumbled upon Dave Wilson Nursery and their Backyard Orchard Culture (BOC) including summer pruning of fruit trees. For me personally, this changed my whole approach to my fruit trees. I primarily have my trees on semi-vigorous rootstock for soil and climate reasons that I won't bore you with (M111, B118, M106). With BOC I've maintained my trees at an easily accessible height of 8 or 10 feet despite my choice of rootstock.
So... after this background info on me and my preferences- looking at your tree I notice what appears to be blue paint on the trunk near your black support rope in the second picture. I assume this tree is grafted then. You may know the rootstock it's on and if this is the case that would influence my pruning advice a bit. For me personally, I'd remove the three lower branches (by the black support rope) making the cut at the branch collar. Over the years growing fruit trees I've settled on a modified central leader pattern for apple trees. You basically have this already with your Winecrisp. I'd make a heading cut on your tallest (dominant) leader to achieve this. Otherwise your tree looks very good. You may wish to use spreaders on the lateral branches and aim for a crotch angle in the 45-60 degree range.
Last it's a young tree so I'd remove most of the apples to allow the tree to put it's energy in to growth saving a few of the nicer apples to sample (I know, hard to do).
Hope this perspective helps some Jeremy!
