New Guinea impatiens are flowers native to Papua New Guinea. The flowers grow wild along the shady banks of riverbeds. Since the introduction of the flowers in the U.S., growers have developed hybrid varieties that are larger and more tolerant of sunlight. New Guinea impatiens may be propagated by rooting tip cuttings. But many varieties of hybrid impatiens are patented by the growers who have developed them. Prior to propagating an impatiens through cuttings, you should first ensure that the plant is not patented.
Place your pruning shears at a point just below where a leaf emerges; there should be two more leaves between this point and the tip of the plant. This point, which is called a node, is where a root will develop. Make your cutting below this third leaf.
Remove all flower blossoms and the leaves on the lower two-thirds of the cutting.
Dip the lower third of the cutting in rooting hormone.
Fill a peat pot with peat moss. Soak the container under a faucet until it is as damp as a wrung-out sponge. Insert the cutting halfway into the moss.
Place the container into a plastic freezer bag. The bag will create a humid environment that will keep the cutting from drying out until it can develop its own roots. Put the bag in a sunny windowsill where it is out of direct sunlight. Remove the bag after the impatiens cutting develops roots.
