Chaenomeles japonica (Japanese Flowering Quince)

Seed Treatment 

  1. Soak the seeds in warm water for 24 hours. 

  2. Cold Stratification: Japanese quince seeds require cold stratification to break dormancy and improve germination.

    • Mix the seeds with moist sand or peat moss in a plastic bag.

    • Store in the refrigerator (34–40°F or 1–4°C) for 90 days.

    • Check periodically to ensure the medium stays slightly moist but not soggy.

Sowing Instructions

  1. Soil Preparation: Use a well-draining seed-starting mix, preferably a mix of sand, peat, and perlite.

  2. Planting Depth: Sow the seeds ¼ inch (6 mm) deep in pots or directly in the garden after stratification.

  3. Watering: Keep the soil moist but not waterlogged. Avoid letting it dry out.

  4. Temperature & Light: Place in a warm location (65–75°F or 18–24°C) with indirect sunlight. Germination may take 1 to 4 months.

  5. Transplanting: Once seedlings are strong enough, transplant them to a sunny location with well-draining soil.
