Propagation & Germination
- Stratification:
- Cold/moist stratification required — 60–90 days
- Germination Time:
- 30–60 days
- Notes:
- Seeds benefit from cold stratification for 60-90 days to break dormancy.
Pre-treatment: Seeds are soaked for 4 hours in 3% hydrogen peroxide and then stratified for 120 days at 3 to 5 C. Alternatively, fresh seeds can be stratified for 12 weeks or older seeds for 25 weeks. Some seeds may benefit from wet tumbling and/or leaching of germination inhibitors.
Establishment: Germination occurs during the stratification period, especially in the later stages. After 60 days of stratification, seeds are checked every other week, and germinants are removed and transplanted. Removing germinants frequently helps to reduce fungal build up in the seed lot during the remainder of stratification, and increases the survival odds for those seeds germinating during stratification. Some protocols suggest the use of rooting hormone for pre-treatment.

ORGHPS Germination Guide: Expose to fluctuation outdoor winter temperatures including freezing for 3 months. Gradually increase light and temperature in the spring. Germination is improved by using GA3. Pulpy coat inhibits germination. Remove by soaking and rinsing in clean water for approximately 7 days. Discard water. * poor germination
