Answer: It is very easy to propagate oleanders from cuttings. There are two good ways; hard wood or tip cuttings. You can try both and see which works best for you. Make tip cuttings about 6' long and remove the lower leaves. The leaf scars or nodes are where the roots will form. Cut the remaining upper leaves to about one inch long. Place the cut ends in a container of water and set in a shady outdoor location. Roots will form in a few weeks. Be sure to change the water every 4-5 days. Once the roots are an inch or two long you can plant them into pots filled with potting soil. Keep them in a shaded area for a few weeks and then gradually move them to a sunny spot.
The second method is to take 6" cuttings, remove the lower leaves, dip the cut end into a rooting hormone (such as Rootone) and stick them into containers filled with moistened potting soil. Again, place in a sheltered location until you see new growth, then gradually move the plants to a sunnier location.
Best wishes with your new plants!
