Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water regularly to keep the soil consistently moist, especially during the growing season. Avoid waterlogged conditions, as this can lead to root rot.
Reduce watering in late summer and autumn as the foliage begins to die back. Ensure good drainage.
Remove spent flower stalks after blooming to prevent seed formation and direct energy back into the bulb. Cut away any yellowing or dead foliage in late summer or autumn.
This helps maintain plant health and prevent disease.
Propagate by separating offsets (bulblets) from the parent bulb during the dormant period, typically late summer or early autumn. Plant the offsets immediately in well-drained soil. Seeds can also be sown in autumn.
Repot clumps every 3-5 years to prevent overcrowding and maintain vigorous growth. This is best done during the dormant season in late summer or early autumn.
Use a well-draining potting mix and plant bulbs at their usual depth.
