Thanks for your thoughtful responses!
I did recently move it to a new spot because it hadn't been getting enough sun. It's currently in the shade next to a sunny south facing window. It's been there about a month and I think it likes it there. So, no need to cut the stem and re-root-- which is what I've read on a few other websites for leggy jades. I just worry that when it does grow, it will get top heavy.
