Growth Stages

Seedling

2-3 weeks

Tiny seedlings with small oval cotyledons emerge within 7-14 days. First true leaves are small and narrow.

Keep soil moist but not soggy. Provide bright light (grow lights if indoors). Maintain warm temperatures 70-75°F. Thin seedlings to appropriate spacing.

Vegetative Growth

3-4 weeks indoors before transplanting; 2-3 weeks after transplanting

Young plants develop multiple sets of narrow, lance-shaped green leaves. Plant becomes bushier and more robust. Stems elongate slowly.

Continue consistent watering. Begin fertilizing every 2 weeks with balanced fertilizer once true leaves appear. Harden off transplants gradually before planting outdoors. Keep temperatures warm (65-75°F).

Pre-flowering

1-2 weeks

Plant reaches mature size with dense foliage. Flower buds begin forming at the tips of central stems. Visible elongation of central stem where flowers will develop.

Maintain consistent moisture and warmth. Switch to a higher phosphorus fertilizer to encourage flowering. Deadhead any early small flower spikes if desired to promote larger blooms. Support tall varieties with stakes if needed.

Flowering

6-8 weeks until frost (continuous if deadheaded)

Tall, narrow flower spikes in pink emerge from stem tips. Flowers open gradually from bottom to top along the spike. Plant can reach 18-36 inches tall depending on variety.

Deadhead spent flowers to encourage continuous blooming. Continue fertilizing every 2-3 weeks. Water deeply during hot spells. Stake tall varieties if needed. These flowers last 6-8 weeks if deadheaded.

Seed Production/End of Season

4-6 weeks (until frost)

If flowers are not deadheaded, flower spikes fade and dry on the plant. Seeds develop in dried flower heads. Plant slows growth as temperatures drop in fall.

Allow some flower spikes to dry on plant for seed collection if desired. Harvest dried spikes for arrangements. Plant dies with first hard frost. Allow self-seeding by leaving spent flowers, or collect and store seeds.
