Right. I found that the ‘trick’ is to control the form of the tree so that it suits your purposes. For my purposes, I first ‘define the fruiting space’, that is, where I want it to fruit so I can (1) see it, (2) spray/tend to it, (3) protect it from predators. That space, for me, becomes a rectangular box about 3-4’ wide, ~6-7’ high, and a convenient length that fits other constraints. The ‘open vase’ shape is for the birds - literally. The good news is that open vase captures the most sun; the bad news, it allows easy access to most predators. The rectangular box I describe is easy to prune to, and, drape netting over. I posted some pics here.
