How to Propagate Rotheca?
Propagation of rotheca can be achieved through semi-hardwood cuttings or seed sowing. Cuttings should be taken in early spring or late summer, with a focus on the stem's healthy, non-flowering sections. Key factors ensuring success include high humidity, consistent temperatures around 20-25°C (68-77°F), and well-draining soil. A shaded environment aids root development, yet bright, indirect light is critical once rooted. The difficulty level is moderate, with challenges in achieving ideal humidity and temperature control. To propagate by cuttings: 1) Snip a 10-15 cm section of semi-hardwood stem. 2) Remove lower leaves, dip in rooting hormone, and plant in moist, well-draining soil. 3) Cover with a plastic bag to maintain humidity and place in indirect light. 4) After 4-8 weeks, check for root development and acclimate gradually before transplanting.
