Care Guide

Watering

Water moderately during the growing season. Keep the soil evenly moist but never waterlogged. Reduce watering once foliage begins to die back after blooming.

Sunlight

Plant in a location that receives full sun to partial shade. At least 6 hours of direct sunlight daily promotes the best flower development.

Soil and Fertilizer

Requires rich, well-draining soil. Amend with organic matter if necessary. Apply a balanced bulb fertilizer in early spring as new growth emerges.

Pruning

Cut back spent flower stalks after blooming to prevent seed formation. Allow the leaves to yellow and die back naturally before removing them, as foliage feeds the bulb for next year.

Propagation Methods

Division

Carefully separate offsets (small bulblets) from the main bulb during the dormant summer period and replant them.
