Propagation of Rinorea domatiosa A.E.van Wyk
Rinorea domatiosa A.E.van Wyk, commonly known as "Forest Pincushion" or "Kruisbessie", is a species of small trees or shrubs native to Southern Africa. It belongs to the Violaceae family and can be propagated by various methods.
Propagation methods
1. Seeds: Rinorea domatiosa plants can be propagated from seeds. The seeds should be collected when they are mature and dry. Sow the seeds in a seed tray filled with moist sand and soil. Keep the tray in a partially shaded area and maintain the moisture level by watering regularly. Germination usually occurs within 4-6 weeks after sowing.
2. Cuttings: Rinorea domatiosa plants can also be propagated from cuttings. Take cuttings that are about 5-10 cm long from the new growth of the plant. Remove the leaves from the bottom half of the cutting and apply rooting hormone to the cut-end. Plant the cutting in a pot filled with a moist mixture of soil and sand. Place the pot in a shaded area and keep the soil moist by watering regularly. The cutting should root within 4-6 weeks.
3. Air-layering: Rinorea domatiosa plants can also be propagated by air-layering. Choose a healthy stem of the plant and make a 1 cm deep cut on the stem, just below a node. Apply rooting hormone to the cut surface and wrap the area with moist sphagnum moss. Cover the moss with plastic wrap and secure with tape. Keep the moss moist by spraying it with water regularly. After 3-4 weeks, roots should have formed on the cutting. Cut the rooted cutting off the mother plant and plant it in a pot with soil.
Propagation of Rinorea domatiosa can be done successfully by any of the above methods. The new plants should be kept in a partially shaded area and watered regularly until they are established.
