Question: How long should stem cuttings be?
Answer: Cutting lengths will vary from 3 to 6 inches, depending on the species involved. (Commercial propagators with access to mist or fog houses will use surprisingly tiny cuttings of soft, succulent new growth.) Choose only healthy wood, and take care to keep the basal portions of each cutting identified. If you accidentally try to root cuttings upside-down, they will fail to grow properly.
