Viola wittrockiana (Pansy)

Seed Treatment

  • Cold Stratification:

    • Place seeds in a moist paper towel, seal them in a plastic bag, and refrigerate for 1–2 weeks before planting.

  • Pre-Soaking: Soak the seeds in lukewarm water for 12–24 hours

Sowing Instructions

Indoor Sowing (Recommended for Early Blooms)

  1. Timing: Start seeds indoors 8–10 weeks before the last frost.

  2. Container & Soil: Use a seed-starting mix in trays or small pots with drainage holes.

  3. Sowing Depth: Lightly cover seeds with 1/8 inch (3mm) of soil—they need darkness to germinate.

  4. Temperature: Keep soil between 65–75°F (18–24°C) until germination occurs.

  5. Lighting: After germination, place seedlings in bright, indirect light or under grow lights for 12–16 hours daily.

  6. Watering: Keep the soil moist but not soggy.

  7. Transplanting: When seedlings have 2–3 true leaves, harden them off before planting outdoors.

Direct Sowing (For Fall or Mild-Winter Climates)

  1. Timing: Sow seeds in late summer to early fall for spring blooms.

  2. Location: Choose a partially shaded to full sun area with rich, well-drained soil.

  3. Sowing Depth: Lightly cover seeds with a thin layer of soil or compost.

  4. Watering: Keep the soil consistently moist until germination occurs.

Germination & Growth

  • Germination Time: 10–21 days.

  • Thinning: Space seedlings 6–8 inches apart for good airflow.

  • Fertilizing: Use a balanced liquid fertilizer every 2–3 weeks for better blooms.

  • Bloom Time: Flowers appear in early spring to summer (or in winter in mild climates).

  • Deadheading: Removing spent flowers encourages more blooms.
