Growth Stages

1

Seedling

2-3 weeks

Tiny seedlings with 2-4 true leaves; very delicate with fine foliage

Keep soil moist but not soggy; provide bright light; thin seedlings to prevent damping-off disease; avoid overhead watering

2

Vegetative

3-4 weeks

Compact bushy growth with increasing foliage density; plant develops multiple stems and reaches 4-8 inches tall

Maintain consistent moisture; fertilize every 2-3 weeks with balanced fertilizer; pinch growing tips if desired to encourage bushier growth; ensure good air circulation

3

Flowering

8-12 weeks

Large pink flowers with ruffled, serrated petals appear; plant reaches full height of 12-16 inches; flowers are 1-1.5 inches across

Deadhead spent flowers regularly to extend bloom period; fertilize every 2 weeks with low-nitrogen formula; water during dry spells; watch for powdery mildew in humid conditions

4

Peak Bloom

4-8 weeks or until frost

Profuse flowering with plant covered in pink blooms; continuous color from early summer through first frost

Increase deadheading frequency; monitor for pests and diseases; maintain consistent watering; provide afternoon shade in zones above 8 to prevent flower fading

5

End of Season

Until frost

Flowering continues but may slow as temperatures drop; plant persists until first hard frost (28°F or below)

Reduce fertilizing as days shorten; stop deadheading if collecting seeds; allow some flowers to go to seed for self-sowing next year; pull plants after hard frost
