Sowing Instructions
Indoor Sowing (Recommended for Early Growth)
-
Timing: Start seeds indoors 6–8 weeks before the last frost date.
-
Containers & Soil: Use a well-draining seed-starting mix in trays or pots.
-
Sowing Depth: Lightly cover seeds with soil (~1/8 inch or 3 mm).
-
Watering: Mist lightly to keep the soil moist but not soggy.
-
Light & Temperature:
-
Maintain a temperature of 65–75°F (18–24°C) for best germination.
-
Provide bright light or a grow light.
-
Germination Time: 14–21 days.
Direct Outdoor Sowing (After Frost)
-
Timing: Sow seeds after the last frost, when soil temperatures reach at least 60°F (16°C).
-
Location: Choose a full sun location with well-draining, sandy or loamy soil.
-
Sowing Depth: Scatter seeds on the surface and cover lightly (~1/8 inch).
-
Watering: Keep the soil evenly moist until germination occurs.

-
Soil Preference: Prefers well-drained, sandy or loamy soil with a pH of 6.0–7.5.
-
Spacing: Thin seedlings to 12 inches apart for proper airflow.
-
Light Requirements: Full sun (6+ hours of direct sunlight daily).
-
Fertilization: Not required in rich soil; otherwise, use a low-nitrogen fertilizer to encourage blooms.
-
Bloom Time: Spring to summer, with vibrant blue flowers that attract bees and butterflies.
