Silene - Coeli rosa mix

1000 seeds

🗓️ When to Sow

• Indoors: Start seeds 6–8 weeks before your last expected frost.

• Outdoors: Direct sow after the last frost, once soil has warmed (above 15°C / 60°F).

• Cool-season tolerant — performs best in spring and early summer.

🌱 How to Sow

✅ Option 1: Indoors (for earlier blooms)

1. Prepare Trays or Pots

   • Use a light, well-draining seed-starting mix.

2. Sow Seeds

   • Sow on the surface — Silene seeds need light to germinate.

   • Do not cover; just press lightly into the soil.

3. Moisture & Light

   • Mist to keep the surface moist (not soggy).

   • Maintain temperature at 65–70°F (18–21°C).

   • Provide bright indirect light or grow lights.

4. Germination

   • Typically 7–14 days.

5. After Germination

   • Thin or transplant seedlings when they have 2–3 true leaves.

   • Harden off before transplanting outdoors.

✅ Option 2: Direct Outdoor Sowing (Recommended for ease)

1. Prepare Site

   • Choose full sun and well-draining soil (light, sandy soils are ideal).

   • Rake soil smooth and water lightly.

2. Sow the Seeds

   • Scatter seeds on the soil surface.

   • Do not cover — press gently into the soil for contact.

3. Watering

   • Mist or water gently to keep soil evenly moist during germination.

🌿 Growing Notes

• Spacing: Thin or plant seedlings 6–8 inches (15–20 cm) apart.

• Height: Grows to about 12–18 inches (30–45 cm) tall.

• Bloom Time: Late spring to early summer.

• Water: Drought-tolerant once established; water during prolonged dry spells.

• Soil: Prefers light, well-drained soils; avoid heavy or soggy soil.
