Seed Treatment

  1. Scarification
    • Rub seeds gently with sandpaper or nick the seed coat with a sharp knife.
    • Soak seeds in warm water for 24 hours to soften the hard outer layer.
  2. Cold Stratification
    • Mix seeds with moist sand or peat moss in a plastic bag.
    • Store in the refrigerator (40°F/4°C) for 4–6 weeks before planting.
    • Check weekly: If seedlings sprout in the fridge, remove them gently and plant immediately.

Sowing Instructions

Indoor Sowing (Recommended for Early Start)

  1. Timing: Start seeds indoors 6–8 weeks before the last frost date.
  2. Container: Use seed trays or small pots with a well-draining seed-starting mix.
  3. Planting Depth: Sow seeds ¼ inch (6 mm) deep and lightly cover with soil.
  4. Temperature & Humidity: Maintain a temperature of 70–80°F (21–27°C). Use a humidity dome or plastic wrap to retain moisture.
  5. Watering: Keep soil moist but not soggy. Mist with water if necessary.
  6. Light: Place under grow lights for 12–14 hours daily.
  7. Germination Time: up to 120 days AFTER stratification (germination can be slow and erratic).

Direct Sowing (For Warmer Climates)

  1. Timing: Plant outdoors after the last frost, when soil temperatures are above 70°F (21°C).
  2. Location: Choose a full-sun spot with well-drained, sandy, or loamy soil.
  3. Planting Depth: Sow seeds ¼ inch deep and cover lightly with soil.
  4. Spacing: Space plants 12–18 inches apart to allow for bushy growth.
  5. Watering: Keep soil evenly moist until seedlings emerge.

Growing & Care Tips

  • Transplanting: Once seedlings have 2–3 sets of true leaves, transplant them to individual pots or into the garden.
  • Watering: Lantana is drought-tolerant once established but needs regular watering during early growth.
  • Pruning: Trim back leggy growth to encourage a bushy, compact shape.
  • Fertilization: Use a balanced fertilizer every few weeks to promote flowering.
  • Pests & Diseases: Watch for spider mites, whiteflies, and aphids. Neem oil or insecticidal soap can help.
