5 short germination tips for Rosa rugosa seeds:
🌹 1. Cold stratification is essential
Keep seeds in moist sand or tissue in the refrigerator for 8–12 weeks to break dormancy.
🌹 2. Scarify lightly (optional)
Gently rub seeds with fine sandpaper or soak in warm water for 24 hours to improve germination.
🌹 3. Use well-draining soil
Sow in a light seed mix (cocopeat + sand/perlite).
🌹 4. Sow shallowly
Plant seeds about 0.5–1 cm deep and lightly cover with soil.
🌹 5. Maintain cool moisture
Keep soil consistently moist and temperature around 18–22 °C until germination. 🌱
