Rhododendron fictola is a species of rhododendron with relatively challenging seed germination.
Here are 5 short tips to help you successfully germinate its seeds:
Cold Stratification: Mimic winter by refrigerating the seeds for 4-6 weeks at 4°C (39°F) in a moist medium (e.g., vermiculite or sand). This helps break seed dormancy.
Soak Seeds: After stratification, soak seeds in water for 12-24 hours to soften the seed coat and promote germination.
Use a Well-Draining Mix: Sow seeds on a surface of acidic, well-draining soil or seed-starting mix (a blend of peat and perlite works well).
Provide Light: Rhododendron seeds need light to germinate, so do not bury them. Just press them lightly into the surface.
Maintain Humidity and Temperature: Keep the soil consistently moist (but not soggy) and maintain a warm temperature of 18-22°C (65-72°F) for optimal germination.
