Growth Stages

1

Seedling

2-3 weeks

Tiny plants with 2-4 true leaves emerge within 7-14 days; very delicate with fine cotyledons

Keep soil moist but not soggy; provide bright light; thin seedlings to proper spacing to prevent crowding and damping off

2

Vegetative Growth

3-4 weeks

Plant develops feathery, finely-divided foliage and a spreading, mounding habit; no flowers yet

Maintain consistent moisture and bright light; pinch back growing tips if desired to encourage bushier growth; avoid overwatering

3

Budding

2-3 weeks

Small buds form at branch tips; plant reaches 8-12 inches tall; foliage becomes denser

Continue regular watering and deadheading nearby spent flowers; apply balanced fertilizer every 2 weeks; ensure adequate airflow

4

Flowering

6-10 weeks (until frost)

Abundant delicate daisy-like flowers in blue, purple, pink, or white appear continuously; plant is full and rounded

Deadhead spent blooms regularly to encourage more flowers; continue fertilizing every 2 weeks; water consistently; may slow blooming in peak heat, revives in cooler weather

5

Decline

Variable; until frost in cool climates

Flowering slows significantly in extreme heat or as temperatures drop; plant becomes leggy; frost kills annual plants

Cut back hard in summer heat and water well to encourage reflowering in fall; in warm climates, plant may self-seed for next year; frost-tender, dies at 32°F
