One of the reasons jade plants are so popular is their easy propagation cycle. Leaves and branches often fall off independently and start rooting right in the pot. Almost any piece you trim off when pruning that has leaves or bud nodules has a chance to root and grow. Cuttings should be at least three inches long for the best results. Let the cutting dry for a day, then place it on a tray of damp vermiculite and peat moss.
