Seedling
2-3 weeksTiny 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
Vegetative Growth
3-4 weeksPlant 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
Budding
2-3 weeksSmall 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
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
Decline
Variable; until frost in cool climatesFlowering 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
