Known for its fluffy, pompom-like blooms in shades of blue, pink, white, and purple, ageratum is a favorite for adding soft texture and cool colors to flower beds, borders, and containers.

🌱 Growing Ageratum from Seed

Step-by-Step Guide:

1. Sow Indoors:

   • 6–8 weeks before the last frost date

   • Sow seeds on the surface of seed-starting mix without covering (light aids germination)

   • Maintain temperature around 21–24°C (70–75°F)

2. Watering & Light:

   • Keep soil moist but not waterlogged

   • Provide bright light or grow lights for best germination

3. Transplanting:

   • Once seedlings develop true leaves, transplant outdoors after frost risk passes

   • Space plants 6–12 inches apart in well-draining soil

4. Sunlight:

   • Prefers full sun to partial shade (4–6 hours of sun daily)

5. Care:

   • Deadhead regularly to encourage continuous blooms

   • Fertilize lightly every 4 weeks during the growing season
