How to Propagate Ninebarks?
Primary propagation methods for ninebarks include softwood cuttings, hardwood cuttings, and division. Success hinges on factors like moisture, light, and using well-draining, fertile soil. Softwood cuttings are best taken in late spring, whereas hardwood cuttings are more suitable in winter. With division, spring or fall is optimal. Propagation by seeds is possible but often less successful due to variable germination. Difficulty is moderate; challenges include maintaining humidity for cuttings and ensuring divisions have adequate roots. To propagate, follow these steps: for cuttings, snip healthy stems, dip in rooting hormone, plant in moisture-retentive soil, and maintain high humidity; for division, separate mature plants at the rootball, ensuring divided parts have roots, and replant immediately.
