"Roses start relatively easily from cuttings. Early summer is the best time when the canes are semi-woody. Cut a 4- to 6-inch-long piece of stem with at least 4 five-leaflet leaves. Remove the lower two five-leaflet leaves, and any flowers or flower buds. Dip the base of the cutting in rooting hormone.
Place cuttings in damp seed starting mix or a peat/vermiculite mixture and water the mix. Cover the cuttings and pot with a plastic bag and place in bright light out of direct sun. Open the bag daily to circulate fresh air, and water as needed to keep the potting mix moist. In several weeks to a month the cuttings should form new roots and can be planted into individual containers."
