Cut a branch from the parent plant, using sharp pruning shears to ensure that the stem is not crushed, minimizing problems from bacteria and other disease-causing organisms.
Remove all leaves from the lower half of the cutting. Also cut off any flowers or buds, since these take energy away from the process of growing roots.
Dip the cut end of each stem in rooting hormone.
Fill a planting tray with several inches of rooting medium.This should be a sterile mixture of perlite and peat moss or a similar combination that allows the cuttings to drain thoroughly and receive plenty of air to the root area. Moisten the contents of the tray.
Plant each cutting about 2 inches deep in the rooting medium. Place the tray in indirect but bright light. Keep it damp but not overly wet until the cuttings develop roots, after which they can be transplanted to their final locations along the desired line of the barrier.
