To propagate oleander from cuttings: Take tip cuttings in the spring when new growth starts to appear on your old woody stems. Cut out some of last year's branches about two inches below a leaf node. Remove any leaves from the lower fourth of the cutting, leaving only two or three small leaves at the top.

Dip your oleander plant cuttings into a rooting hormone powder and then simply plant into a pot with potting mix. To root oleander cuttings a little faster, put a seedling heat mat underneath the pot and cutting. You can also create a humid “greenhouse” by placing a clear plastic bag over the pot.
