Earlier this spring when my very young Chicago Hardy tree came out of dormancy and started growing it was a single “whip” about two feet tall with no branching whatsoever. There was a small group of leaves at the very top. I had recently read this post about pruning of figs:

I was particularly intrigued by post #15 from nkesh099 who said that for best productivity it is best to have a tree with several branches that come out horizontally from the main stem a couple inches above ground level – pretty much the opposite of the way my Chicago Hardy was growing.
So on the morning of May 5 on the way to work I bit the bullet and removed all but the lower 4 inches or so, including all leaves.
After about 2 weeks there was no growth and I began to worry that I had killed it. But then I saw a green bud and another. By June 7 you can see that it had recovered nicely. So at least for this variety you can get away with some pretty extreme pruning and the tree will recover just fine. Next I will try to train the new branches to protrude out at an angle closer to horizontal.
