Propagation & Germination
- Stratification:
- Cold/moist stratification required — 30–60 days
- Germination Time:
- 14–30 days
- Notes:
- Seeds benefit from cold stratification for 30-60 days to improve germination.
Pre-treatment: Seeds are placed in cold moist stratification for 6 to 12 days. A short prechill decreases germination time. Use of gibberellic acid combined with 16 weeks stratification can improve germination.
Establishment: Fertilizer application is not recommended in the first year as it stimulates weed growth. Germination rates and times can vary depending on the source of the seed and the specific treatments applied. Germination may occur most readily in the spring.
