How to Start Feverfew Seeds

1. Start indoors 4–6 weeks before your last expected frost, or direct sow outdoors after frost danger has passed.
2. Sow on the surface of moist seed-starting mix and press gently into place. Seeds need light to germinate, so avoid burying them deeply.
3. Keep the growing medium evenly moist, but not waterlogged.
4. The listed germination window is approximately 14–21 days at 68°F; timing varies with conditions.
5. Gradually acclimate indoor-grown seedlings to outdoor conditions before transplanting. Thin or space plants approximately 24 inches apart.

Growing & Flower Care

• Choose a sunny site with well-drained soil.
• Water as needed to support establishment, avoiding persistently wet soil.
• Feverfew can self-seed freely. Remove spent flower heads before seed develops if you want to limit volunteer seedlings.
• Cut flowering stems for small bouquets, or dry them in a well-ventilated location for decorative use.
