Growth Stages

1

Seedling

2-3 weeks

Small plants with 2-4 true leaves and delicate stems; cotyledons emerge within 5-10 days

Keep soil moist but not soggy; provide bright light and good air circulation; thin seedlings to prevent damping off

2

Vegetative

3-4 weeks

Plant develops branching stems and more foliage; leaves are finely divided and ferny in appearance; bushy shape forms

Pinch back growing tips when 6 inches tall to encourage bushiness; maintain consistent watering; fertilize every 2-3 weeks with balanced fertilizer

3

Budding

1-2 weeks

Flower buds begin to form at stem tips; plants reach 12-24 inches tall depending on variety

Continue regular watering and fertilization; deadhead any early flowers to encourage more blooms; ensure adequate sunlight

4

Flowering

8-12 weeks (until frost)

Large, full double or single golden-yellow blooms appear; plants become covered with flowers; sweet, spicy fragrance is noticeable

Deadhead spent flowers weekly to promote continuous blooming; water deeply when top inch of soil is dry; reduce nitrogen fertilizer

5

Seed Production

3-4 weeks after flowering

If flowers are left undeadheaded, they develop seed pods with long, dark seeds inside papery sepals

Allow some flowers to mature and dry on plant if seeds are desired for next year; collect seeds when pods turn brown and papery
