Daphne cuttings are best taken from December-January, using wood of the current season's growth that has not flowered but has become firm (semi-hardwood).
Take stem cuttings, with leaves removed from the lower 300 mm and allow to dry out (in a cool place out of direct sunlight) before planting. Insert the cuttings into pots of Yates Seed & Cutting Potting Mix. Cover the cuttings with glass or a clear plastic bag to maintain warmth and humidity, and water regularly to keep the potting mix moist. Cuttings will take up to six months to establish.
Plants can also be propagated through a method called layering. In January, choose a stem that is close to the ground level. Cut the stem at an angle, partially through, closest to the soil, and insert a matchstick into the cut to keep it open. Dig a shallow trench and secure the stem to the soil using pegs.
