Seed Preparation and Sowing

• Sowing Method:
  • Cold stratify seeds for 4-6 weeks before planting to improve germination.
  • Sow indoors in seed trays 6-8 weeks before the last frost or directly outdoors in early spring.
  • Press seeds lightly into the soil without covering, as they need light to germinate.

• Fertilization: Apply a balanced, slow-release fertilizer in early spring.
• Pruning: Trim back spent flowers and foliage to encourage reblooming.
