7000 seeds

🗓️ When to Sow

• Indoors: Start 8–10 weeks before your last expected frost date.

• Outdoors: Not recommended — seeds are tiny and delicate. Best started indoors.

🌱 How to Sow Indoors (Preferred Method)

1. Prepare Containers

   • Use shallow seed trays or cell packs filled with fine, moist, well-draining seed-starting mix.

2. Sow the Seeds

   • Lobelia seeds are extremely fine — do not cover with soil.

   • Lightly sprinkle seeds on the surface of the soil.

   • Gently press down to ensure contact.

   • You may mix seeds with a bit of fine sand for even distribution.

3. Moisture & Light

   • Mist gently to moisten the surface without disturbing the seeds.

   • Cover with a clear lid or plastic wrap to maintain humidity.

   • Keep in bright light but out of direct sun until germination.

4. Temperature

   • Maintain 65–70°F (18–21°C).

   • Germination time: 14–21 days.

🌿 After Germination

• Remove cover once seedlings emerge.

• Water from the bottom or mist carefully to avoid damping off.

• Thin or prick out when seedlings have 2–3 true leaves.

🌸 Transplanting Outdoors

• Harden off for 7–10 days before transplanting outside.

• Plant spacing: 4–6 inches (10–15 cm) apart.

• Choose a location with:

  • Full sun to partial shade (light afternoon shade in hot climates).

  • Moist, well-draining soil enriched with compost or organic matter.

🌼 Growing Tips

• Keep soil consistently moist — Lobelia dislikes drying out.

• Excellent in containers, borders, or cascading over edges.

• Trim lightly after the first flush of blooms to encourage reblooming.

• ‘Rosamund’ is especially suited to cool-season displays, often blooming spring to early summer and again in early fall.
