How to Propagate Gunnera?
Primary propagation methods for gunnera include seed sowing, division, and root cuttings. Key factors for successful propagation involve maintaining high humidity, warm temperatures, and utilizing rich, well-draining soil. Special considerations include ensuring the large rhizomes aren't damaged during division and that seedlings are kept moist. Propagation can be challenging due to the plant's size and sensitivity to environmental changes. For division: 1) Carefully excavate around the plant, 2) Separate the rhizome into sections with at least one growth bud each, 3) Plant sections in the appropriate substrate, 4) Maintain consistent moisture and warmth.
