How to Propagate Retrophyllum?
Propagation of retrophyllum primarily involves seed sowing, with cuttings being an alternative. Successful germination requires attention to light exposure, consistent warmth, and a well-drained growing medium. Seeds might exhibit dormancy, requiring stratification or scarification to encourage sprouting. Propagation can be moderately difficult due to the potential for low germination rates and the slow growth of cuttings. Follow these steps for seed propagation: 1) Scarify or stratify seeds if necessary, 2) Sow seeds in a well-draining substrate, 3) Maintain temperatures of 20-25°C, 4) Ensure indirect sunlight, and 5) Keep soil consistently moist but not waterlogged. Cuttings require a similar environment with added humidity.
