They are easy to root in the first half of the season. I don't know about this late in the year, but it is worth a try.

Root them as if you would root anything else. Rootone is optional, but helps. They prefer a bit of warmth when rooting. No special treatment beyond this is needed.

i have successfully rooted dinner plates in just plain old tap water just take tip cuttings right after the new growth hardens off a bit. take several some will die and once they root pot them up and keep them moist in a shady spot. they can then be transplanted where you want them the following spring
