Growth Stages

1

Seedling

2-3 weeks

Tiny seedlings emerge with fine cotyledons. Early leaves are feathery and delicate.

Keep soil moist but not soggy. Provide bright light to prevent leggy growth. Thin seedlings to proper spacing early.

2

Vegetative Growth

3-4 weeks

Plant develops lacy, finely divided foliage and establishes a bushy form. Stems elongate and branches develop.

Ensure adequate spacing for air circulation. Pinch tips early to encourage bushier growth if desired. Water consistently.

3

Bud Formation

2-3 weeks

Flower buds begin to form at branch tips. Plant reaches near mature height with dense, airy foliage.

Apply balanced fertilizer or dilute liquid fertilizer. Maintain consistent moisture. Support tall varieties with stakes if needed.

4

Flowering

6-8 weeks

Delicate white lacy flower umbels open in succession. Flowers create an ethereal, cloud-like appearance.

Deadhead spent flower clusters to encourage more blooms. Cut stems for arrangements to prolong flowering. Fertilize every 2-3 weeks.

5

Seed Production

4+ weeks

If flowers are not harvested, they develop fine seeds in characteristic umbel patterns. Plant begins to decline as energy shifts to seed production.

Allow some flowers to mature for self-seeding if desired. Reduce watering slightly as plant naturally declines.
