How to Propagate Sinojackia?
Primary propagation methods for sinojackia include seed sowing and cuttings. Key factors for success are light exposure, consistent moisture, well-draining soil, and temperatures around 65-75°F (18-24°C). Special considerations involve pretreating seeds for increased germination rates and using rooting hormone for cuttings. Propagation can be somewhat challenging due to seed dormancy and the delicate nature of cuttings. To propagate by cuttings: 1) Take a 4-6 inch cutting from a healthy branch in early summer, 2) Dip the cut end in rooting hormone, 3) Plant in a mixture of peat and perlite, 4) Keep the soil moist and provide indirect light, 5) Transplant once rooted. For seeds: 1) Stratify seeds by chilling for several weeks, 2) Sow in well-draining soil in spring, 3) Maintain consistent moisture and light exposure, 4) Transplant seedlings when sturdy enough.
