You can give layer them or give cuttings another shot. To layer them, make a cut about one-third of the way into a new side shoot. Brush the cut with rooting hormone. Leaving the shoot attached to the shrub, bend it down and bury the cut spot in a shallow trench. You might need to make a long loop-type stake from a wire coat hanger to pin it down. This method will take some time, but within a year your wound will have sent out roots and you'll have a new plant. Cuttings might be simpler, especially if you want several new Camelias. Take cuttings anytime between May and September. Your cuttings should be the current season's growth; cut just below the 5th node. (This specific cutting advice comes from woody plant genius Michael Dirr.) Dip the cuttings in rooting hormone and stick them into a mix of peat with sand or perlite. While the cuttings are rooting, make sure they don't dry out. It might be a good idea to suspend a plastic cover loosly around your rooting bed to maintain high humidity.
