- 6.0 - 7.5 (slightly acidic to neutral)
- Drainage:
- excellent drainage required

Propagation & Germination
- Stratification:
- Warm then cold/moist stratification (double dormancy) — 90–120 days
- Germination Time:
- 30–120 days
- Notes:
- Juniper seeds have deep dormancy; warm stratification followed by cold stratification improves germination. Germination can be erratic.
The above propagation data sourced from Claude AI
Pre-treatment: Cold-moist stratification for 30 days at 1–5°C (34–41°F).; then Cold-moist stratification for 90 days.
Notes: Seeds may require light for optimal germination.
