Many of your regular ole artificial trees have branches that you stick into a pole. I would assume you can just simply not put that side's branches on.

Michiel, if you are going to try to use a tree with branches on one side, make sure you weigh the base down quite well or it WILL tip over.
If you want an actual half tree, I'd check with Kmart or Garden Ridge (if you have one nearby) in early October. JCPenney has half trees on page 62 of the just-coming-out Christmas catalog, but the smallest is 6 feet tall.
Good luck!

HAY HOBBY LOBBY HAS THEM .......

check out www.treeclassics.com. They sell half trees that are flat on one side. They are gorgeous and well made

I just don't put the back branches on my tree.I don't want to have to remove my corner cabinet,so without the back branches it.work very well.
kathi snuggles up nicely to the cabinet.Then as the other poster said,weigh it down.I do this with a paver from outside.Then after i put the tree skirt under the tree,you can't even tell it's there.
