My tree has been growing a lot lately, but almost entirely on one side. I think part of the lean is due to me letting a lemon grow over there while the tree was kind of small. A question for the experts here though, will this straighten up as it grows more? Would it be safe to prune that long branch on the side back a bit to try and reduce the lean? If I prune it, would that be a suitable piece to try to use some rooting hormone on and get another tree going?

Thanks in advance for any tips.

Yea of course you can make cuttings very easily.
Take the branch about 8 inches take of all leaves except like 2 on the tip and stick it in a very free draining soil and keep it in a nice humid enviroment.
I think laaz or millet will pitch in if I missed something.
