Growth Stages

1

Dormancy/Chilling

12-16 weeks

Bulbs are dormant underground, requiring a winter chill period of 12-16 weeks

Store bulbs in cool (35-45°F), dry conditions. Plant in fall or early spring depending on climate. Ensure bulbs are firm and disease-free.

2

Emergence & Vegetative Growth

4-6 weeks

Shoots emerge from soil, developing multiple stems and lance-shaped leaves; vigorous upward growth

Water regularly as growth accelerates. Apply balanced fertilizer every 2-3 weeks. Stake tall varieties for support. Remove any weak shoots if desired.

3

Budding & Pre-Bloom

2-3 weeks

Flower buds form at stem tips; buds elongate and begin showing color

Continue regular watering and fertilizing. Switch to higher-phosphorus fertilizer to support flower development. Ensure adequate light for optimal coloration.

4

Flowering

3-4 weeks

Large, golden-yellow flowers open in succession, displaying recurved petals and prominent stamens; intense fragrance

Deadhead spent flowers to encourage additional blooms on the stem. Support heavy flower heads with ties if needed. Enjoy cut flowers; they last 2-3 weeks in a vase.

5

Post-Bloom & Senescence

3-4 weeks

Flowers fade, foliage gradually yellows and dies back naturally

Do not cut foliage until completely brown; leaves feed the bulb for next season. Reduce watering. Allow bulbs to dry and cool for dormancy. Divide overcrowded bulbs if needed.
