Buddleja davidii (Butterfly Bush)

Seed Treatment (Pre-Planting Preparation)

  1. Cold Stratification:

    • Mix seeds with moist sand or a damp paper towel and place them in a sealed plastic bag.

    • Store in the refrigerator (35–40°F / 2–5°C) for 4–6 weeks.

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

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

Planting Instructions

  • Best Planting Time: Early spring (after stratification) or late winter indoors.

  • Soil Requirements: Well-draining, light soil; a mix of peat and perlite works well.

  • Sunlight: Full sun is ideal for healthy growth.

  • Planting Depth: Do not cover seeds, as they need light to germinate. Press them lightly onto the soil surface.

  • Spacing: 12–24 inches (30–60 cm) apart for multiple plants.

  • Watering: Keep the soil consistently moist but not soggy during germination.

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

  • Germination Time: 2–6 weeks.

Care After Germination

  • Thin seedlings once they develop their first true leaves.

  • Transplant seedlings into larger pots once they reach 2–3 inches (5–8 cm) tall.

  • Harden off plants before transplanting outdoors by gradually exposing them to outdoor conditions over 7–10 days.

  • Water regularly, but avoid overwatering.

  • Prune yearly to maintain shape and encourage blooms.
