Propagation of Ochna cinnabarina Engl. & Gilg
Ochna cinnabarina Engl. & Gilg, commonly known as the carnival ochna or carnival redwood, is a popular ornamental plant native to South Africa and Swaziland. It belongs to the Ochnaceae family and grows up to 4 meters tall with a spread of 3 meters. The plant produces bright yellow flowers in spring, followed by small reddish-black fruits in summer.
There are several methods to propagate Ochna cinnabarina Engl. & Gilg, including:
Seed Propagation
The seeds of Ochna cinnabarina Engl. & Gilg can be collected from mature fruits in summer and sown immediately. Soak the seeds in warm water for 24 to 48 hours to enhance germination. Sow the seeds in a well-draining potting mix and cover them lightly with soil. Water regularly and keep the soil moist until the seeds germinate, which usually takes 4 to 6 weeks. Once the seedlings have developed two or three leaves, transplant them into individual pots or containers.
Cutting Propagation
Ochna cinnabarina Engl. & Gilg can be propagated by stem cuttings taken in spring or summer. Select healthy stems that are 10 to 15 centimeters long and remove the leaves from the lower half of the stem. Dip the cut end in rooting hormone powder and plant the cutting in a pot filled with a well-draining potting mix. Water the cutting thoroughly and cover it with a plastic bag to maintain high humidity. Place the pot in a warm, bright, and sheltered location, away from direct sunlight. The cutting should root within 4 to 6 weeks. Once rooted, transplant the cutting into a slightly larger pot and treat it as a mature plant.
Air Layering Propagation
Air layering is a propagation method that involves rooting a branch while it is still attached to the parent plant. In spring or early summer, select a healthy stem and make a shallow cut on the branch's lower side, about 10 to 15 centimeters from the plant's tip. Apply a rooting hormone to the exposed area, wrap sphagnum moss around the cut, and cover it with plastic wrap. Secure the moss and plastic wrap with tape or string and keep the area moist. After a few weeks, roots should start to grow from the moss. Once the roots are well-developed, cut the branch from the parent plant and transplant it into a pot or container.
Propagation of Ochna cinnabarina Engl. & Gilg can be a satisfying experience and a great way to share this beautiful plant with friends and family. By using the right techniques, you can easily propagate Ochna cinnabarina Engl. & Gilg and enjoy its beauty for years to come.
