Growth Stages

1

Dormancy

3-4 months (typically November-February)

Bulb is at rest, either dry or in cool storage with minimal foliage visible

Store in a cool, dry location (50-60°F). Keep soil very dry. Do not water.

2

Emergence & Vegetative Growth

4-6 weeks

New shoots emerge from the bulb, developing broad, strappy leaves that form a basal rosette

Begin regular watering as growth starts. Apply balanced fertilizer monthly. Ensure good drainage.

3

Flower Bud Development

3-4 weeks

A thick flower stem emerges from the center of the foliage, with a developing inflorescence bud visible at the apex

Continue consistent moisture and monthly fertilization. Provide bright, indirect light. Support tall stems if needed.

4

Flowering

2-4 weeks

Spectacular spherical flower head (umbel) opens with densely packed small red, orange, or crimson flowers arranged in a dramatic globe

Maintain consistent moisture. Protect from strong winds. Remove dead flowers to encourage longer blooming.

5

Senescence & Dormancy Preparation

4-6 weeks

Flower fades, foliage begins to yellow and die back as the plant prepares for dormancy

Gradually reduce watering. Allow foliage to fully dry back. Stop fertilizing. Prepare for winter rest.
