Primary methods for propagating rivina include seed sowing and cuttings. Key factors are warm temperatures, high humidity, and well-draining soil. Special considerations: seeds require light to germinate, so press into soil, don’t cover. Semi-ripe cuttings root best. Difficulty level is moderate. For seeds: 1. Scatter seeds on seed-starting mix, press in, mist. 2. Maintain 20-25°C. 3. Keep moist, not waterlogged. 4. Transplant seedlings after 2-3 leaves form. For cuttings: 1. Take 4-6 inch cuttings. 2. Remove lower leaves. 3. Insert into moist potting mix. 4. Enclose in a plastic bag to retain humidity. 5. When rooted, pot on.
