Magnolia doltsopa, commonly known as Sweet Michelia or Himalayan Michelia, is an evergreen tree native to the eastern Himalayan region, prized for its sweetly fragrant, creamy-white flowers and ornamental value. This species requires cold stratification for 60-90 days to break seed dormancy and achieve optimal germination rates. Seeds germinate within several weeks to a few months when provided with proper moisture, light, and warm temperatures following the stratification period.
Before sowing
Remove fleshy red seed coat by soaking overnight in warm water and rubbing against hardware cloth. Stratify in refrigerator for 60-90 days in moist vermiculite, peat, or sphagnum moss at 4°C (40°F)

What to expect
Tips
Always remove the fleshy red seed coat before stratification, as it can inhibit germination. Keep the substrate moist but not waterlogged during the entire process. Provide light after stratification, as seeds require light to germinate. Maintain partial shade after germination and for the first summer. Use a transparent container or zip-lock bag to maintain humidity and monitor progress. Temperature alternation between day and night (24-28°C day, 20-24°C night) enhances germination. Ensure good drainage to prevent seed rot.
