How to Propagate Thunbergias?
Thunbergias can be propagated mainly through seed sowing, stem cuttings, or layering. Optimal propagation requires warm temperatures, bright indirect light, and well-draining soil. Seeds should be sown in spring or summer, while cuttings and layering can be performed in late spring. Special considerations include using rooting hormone for cuttings and ensuring high humidity. The difficulty level is moderate, with challenges including managing moisture levels to prevent root rot. To propagate by cutting: 1. Cut a 4-6 inch stem segment just below a leaf node. 2. Remove lower leaves, dip in rooting hormone, and plant in moist potting mix. 3. Cover with plastic to retain humidity and place in indirect light. 4. Keep soil consistently moist and expect roots in 3-4 weeks.
