Seed Starting Guide
When to Plant: Fall (Preferred) - plant seeds in late October to December in mild climates. Mimics natural germination for earlier spring blooms.
Spring: Sow as soon as the soil is workable and frost danger has passed.

How to Sow: Scatter seeds on bare, well-drained soil. Press them lightly into the surface—they need sunlight to germinate. Water gently to ensure good seed-to-soil contact.
Watering: Keep the soil evenly moist during germination (1–2 weeks). Once seedlings are established, allow the soil to dry slightly between irrigation.

Care: No fertilizer needed; too much fertility can reduce flowering. Avoid overwatering to prevent root rot.
