The above propagation data sourced from Claude AI
Pre-treatment: Seed sown in sand and given a 60 day cool/moist stratification period in cooler at 40 F, 30% relative humidity. Seed-sand mixture drenched with fungicide such as Captan or Triathlon to prevent mildew in moist stratification.
Establishment: Recommended to start in early fall for outplanting the following spring as plugs. Larger sized containers may require another season of growth.
