Forsythia suspensa

Seed Treatment (Pre-Planting Preparation)

  1. Cold Stratification: Forsythia suspensa seeds require cold stratification to break dormancy.

    • Place seeds in a moist paper towel or sand inside a sealed plastic bag.

    • Store in the refrigerator (35–40°F / 2–5°C) for 60–90 days.

    • Check periodically to ensure they remain moist but not soggy.

  2. Soaking: Soak seeds in lukewarm water for 12–24 hours before planting.

Planting Instructions

  • Best Planting Time: After stratification, plant in early spring.

  • Soil Requirements: Well-draining, fertile soil with a pH of 6.0–7.5.

  • Sunlight: Full sun to partial shade.

  • Planting Depth: Sow seeds 1/8 inch (3 mm) deep and lightly cover with soil.

  • Spacing:12–18 inches (30–45 cm) apart if growing multiple plants.

  • Watering: Keep the soil moist but not waterlogged until germination.

  • Germination Temperature: 65–75°F (18–24°C).

  • Germination Time: 4–12 weeks (sometimes longer).

  • Transplanting: Once seedlings reach 4–6 inches (10–15 cm) tall, they can be transplanted to their permanent location.

Care After Germination

  • Water regularly, especially during dry periods.

  • Prune after flowering to encourage bushier growth.

  • Forsythia is a hardy shrub that can tolerate various soil conditions once established.
