Yes, you can, you score it a few times with a sharp knife, use good "potting soil" in a 3 gal. Pot, use pine mulch in bottom of, so soil won't come out when watering and in a couple of weeks you should have a "rooted" crape myrtle. I would suggest you leave in pot for at least 6 to 8 mos. To be sure it is rooted well. Good luck.
