How to Propagate St. John's worts?
Primary propagation methods for st. John's worts include seed sowing after stratification, semi-ripe cuttings in summer, and division in spring or autumn. Successful growth largely depends on adequate light, temperature moderation, and well-draining soil with slight acidity. Specific to st.

To propagate from cuttings: 1) Cut 3-4 inch semi-ripe stems in summer, 2) Remove lower leaves, 3) Dip cut end into rooting hormone, 4) Plant in a mix of sand and peat, 5) Maintain high humidity and indirect light, 6) Transplant once rooted.
