Ferroplasm,
Looks like I have the same scenario like yours. I planted my fuyu last spring. It started leafed/branched out in the mid season from the bottom up. I cut off the bottom part and leave the top part to encourage the plant to leafed out more on top rather than at the bottom. Good luck

If thats all the tree grew last year you may just want to let it put on some more growth. Or if you want to keep it lower take off that top bit.

You can prune any time, don't worry about getting it while dormant. Well, early fall is not the best time. But any other time of year you can prune.

Thanks, scottfsmith. I guess I'll keep it unpruned for now. It really didn't grow much last year, which isn't abnormal from what I've read. I'll see how it responds this spring and summer to a small amount of fertilizer and probably decide whether it needs a trim next winter.
