Planting

Start early and transplant after frost.

Sow indoors 8–10 weeks before the last frost. Cover lightly, keep warm, and move seedlings into strong light immediately after emergence.

01

Use clean fine seed mix

Moisten before sowing and space seed so seedlings can be lifted cleanly.

02

Cover about ⅛ inch

Maintain warmth and even moisture through the variable germination period.

03

Plant 12–18 inches apart

Harden gradually and set into full sun and well-drained soil after frost.

Ongoing care

Keep the carpet sunny, open, and flowering

Maximize full sun

Strong light produces compact spreading growth and the heaviest bloom.

Water deeply after planting

Once established, allow the surface to dry slightly between waterings.

Avoid rich soft growth

Moderate fertility keeps plants dense instead of lanky.

Shear tired stems lightly

Trim spent clusters and leggy growth to encourage a fresh flush.

Season checkpoints

Use plant spread and flower density as guides.
