This is the only tree out of the four where I had total control of the shape as it was a one year old seedling when I got it and the trunk was still bendable. I gave it a slight curve and let the years do it's thing on it.
Let it grow long and thicken and then cut it off when the taper is right. As I said, none of these trees will be works of art but the years of seeing them come into something better than they started out, made it all worth it.
