The above propagation data sourced from Claude AI

Pre-treatment: For seeds: Cold moist stratification for 60 to 120 days or soaking fresh seed for 24 hours, discarding floaters, and placing viable seeds in the refrigerator with dry perlite. For cuttings: Dip in a mild bleach solution for 30 seconds and treat with Hormex rooting powder.

Establishment: Seeds are recalcitrant and must not dry out after collection. Cuttings should have at least 3 nodes. There is a variation in the pre-treatment and establishment protocols for seeds and cuttings.
