What you need to know to Plant & Grow
Double Shirley Poppy features a delicate taproot system that resents transplanting, making direct outdoor sowing the best method for success.
-
Outdoor Direct Sowing (Recommended): Sow seeds directly outdoors in early spring as soon as the soil can be worked. Choose a site in full sun to partial shade with well-drained soil. Direct sow into lightly disturbed soil, avoiding heavy, wet clay beds.
-
Sowing Depth & Germination: Scatter seeds thinly across the soil surface and barely cover with a light dusting of fine soil—light aids germination. Keep the soil consistently moist throughout the brief 5 to 10 day germination period.
-
Thinning & Care: Thin young seedlings to 20 to 25 cm apart once established. Deadhead spent blooms regularly to prolong the flowering season, or allow seed pods to dry on the plant for natural self-sowing in subsequent seasons.
