The above propagation data sourced from Claude AI
Pre-treatment: For seeds, cold moist stratification at 40 degrees F for 8 weeks or mix seeds with perlite or vermiculite and cold store at 33-42 degrees F for one month. For cuttings, rhizome divisions with at least 3 leaf bud shoots per rhizome are divided from nursery stock and planted into individual containers.
Establishment: Sweetgrass is a cool season species and its seeds require a period of cold temperatures before they germinate. Late fall, late winter and early spring are the best times to sow seeds. Sweetgrass inconsistently produces seeds. Seeds can be collected in late summer. Rhizome divisions were separated from established nursery plants.
