Growth Stages

1

Seedling

2-3 weeks

Tiny seedlings with narrow cotyledons emerge and develop their first true leaves. Growth is slow initially.

Provide bright light and maintain consistent moisture. Keep temperatures around 70-75°F. Thin seedlings if direct seeding.

2

Vegetative Growth

3-4 weeks

Plants develop bushy foliage with narrow, blue-green linear leaves. Stems become sturdy and branching increases.

Maintain regular watering and apply balanced fertilizer every 2-3 weeks. Pinch back growing tips at 4-6 inches to encourage bushiness.

3

Budding

2-3 weeks

Small flower buds appear at stem tips. Plants continue to grow denser with more branching.

Continue watering and feeding. Reduce nitrogen slightly to encourage flowering. Deadhead any early sparse flowers.

4

Flowering

8-12+ weeks (continuous until frost)

Bicolor flowers with pink/red petals and white centers/edges open profusely. Plants are full and compact.

Deadhead spent flowers regularly to encourage continuous blooming. Water consistently and fertilize every 2 weeks with bloom-promoting formula (higher phosphorus).

5

Decline

Variable with climate

Flowering slows in extreme heat or as temperatures cool toward fall/frost. Plants may become leggy.

In hot climates, provide afternoon shade. Continue deadheading. Plants are frost-tender; remove after first hard freeze in colder zones.
