Propagation of Diascia Stricta Hilliard & B.L.Burtt
Diascia stricta Hilliard & B.L.Burtt, commonly known as Twinspur, is a popular flowering plant that grows well in containers or garden beds. It can be propagated by seeds, cuttings or division.
Propagation by Seeds
The easiest method of propagation for Diascia stricta is by seeds. Seeds can be collected from the plant or purchased from nurseries. They should be sown indoors in early spring, preferably in a well-draining potting mix. Cover the seeds lightly with soil and keep the soil lightly moist. Seedlings should emerge within 2-3 weeks and can be transplanted into larger pots or into the garden after the last frost.
Propagation by Cuttings
Diascia stricta can also be propagated via stem cuttings. Cuttings should be taken in late spring or early summer from new growth. Cut off a stem with at least two pairs of leaves and remove the lower pair of leaves. Dip the end of the stem in rooting hormone and stick it into a well-draining potting mix. Keep the soil moist and cover the pot with a plastic bag to retain moisture. Place the pot in a bright, but not direct, light and wait for the cuttings to root. Transplant the rooted cuttings into larger containers or the garden after they have developed a strong root system.
Propagation by Division
Diascia stricta can be divided in late summer or early fall when the plant is dormant. Carefully dig up the clump and separate the individual plants using a sharp, sterile knife. Make sure that each new plant has a good root system and several stems with leaves. Replant each new division in a container or in the garden in a well-draining soil. Water the newly transplanted divisions regularly until they are established.
