Planting

Use a sunny bed that drains quickly.

Direct sowing minimizes root disturbance and makes an easy low ribbon of bloom.

01

Prepare loose drained soil

Remove weeds and break crusted soil before planting.

02

Sow about ¼ inch deep

Cover lightly and maintain even moisture until seedlings establish.

03

Thin for airflow

Leave 6–10 inches between plants and avoid crowding the crown.

Ongoing care

Keep plants healthy and flowers productive

Maximize sun

Full sun keeps plants compact and flowering freely.

Water without saturation

Allow the surface to begin drying between deeper waterings.

Keep fertility modest

Lean to average soil prevents soft growth.

Shear fading clusters

A light trim tidies plants and may encourage additional bloom.

Season checkpoints

Follow the plant’s visible progress.

14–21 days

Shear lightly

Cutting and display

Cut when most of a cluster is open.

For small arrangements, cut stems when the flower cluster is mostly open but still fresh. Condition quickly because short branching stems can wilt after harvest.

  1. Cut in the cool morning.
  2. Use clean sharp snips.
  3. Recut and place in fresh water.
