Soil Requirements
- Soil Type:
- rich, well-drained loamy soil
- pH:
- 5.5 - 7.0 (slightly acidic to neutral)
- Drainage:
- good drainage required
- Moisture:
- consistently moist

Propagation & Germination
- Stratification:
- Warm then cold/moist stratification (double dormancy) — 60–120 days
- Germination Time:
- 30–180 days
- Notes:
- Double dormancy common; warm stratification followed by cold stratification improves germination. Germination can be slow and erratic.
The above propagation data sourced from Claude AI
Pre-treatment: For seeds: Treated with 1,000 ppm gibberellic acid for 24 hours, followed by a 48 hour running water rinse. Placed into a 60 to 90 day cold, moist stratification at 3 C. For cuttings: Re-cut and terminal buds removed. Given a 2 minute Domain fungicide bath. Treated with 2000 ppm liquid IBA rooting hormone. Cut into 15 centimeters length with an average caliper of 7mm.
Establishment: Cuttings collected at leafbud break in early spring had the highest rooting percentage. Fully dormant hardwood cuttings may yield higher rates of rooting. Seeds germinated at 3C after 60 days of stratification. Do not sow seeds until there is visible cracking or radicle emergence.
