How to Propagate Interrupted fern?
Primary propagation methods for interrupted fern include spore sowing and division. Success hinges on optimal light, temperature, and moisture-retentive, well-draining soil. Special techniques like cold stratification may enhance germination. Propagation can be challenging due to slow spore germination and careful division. Propagate by division in spring: 1) Dig up the plant, gently separating the root clump. 2) Cut through the crown to create sections with fronds and roots. 3) Replant divisions immediately, maintaining consistent moisture. For spores: 1) Collect spores when ripe. 2) Sow on the surface of a sterile, moist medium. 3) Maintain high humidity and indirect light until germination occurs.
