Growth Stages

1

Dormancy

4-6 months

Bulbs are at rest underground, typically from late spring through early winter in cool climates

Store bulbs in a cool, dry place. Do not water. Keep temperature around 50-55°F for proper dormancy period.

2

Sprouting

2-3 weeks

Shoots emerge from soil and develop narrow, linear leaves

Begin watering regularly once shoots appear. Ensure good drainage. Apply light liquid fertilizer.

3

Vegetative Growth

4-6 weeks

Plants develop tall, slender stems with multiple linear leaves; bushy foliage at base

Water consistently, maintain full sun exposure. Stake tall varieties for support. Continue light feeding every 2-3 weeks.

4

Flowering

4-8 weeks

Star-shaped flowers bloom in dense spikes; flowers open sequentially from bottom to top

Remove spent flowers to encourage continued blooming. Avoid overhead watering. Provide support if needed. Cut stems make excellent long-lasting cut flowers.

5

Seed Production & Dormancy Preparation

3-4 weeks

Flowers fade and seed pods develop; foliage begins to yellow and die back

Deadhead if not collecting seeds. Gradually reduce watering. Allow foliage to yellow completely before removing. Stop fertilizing.
