How to grow

Cultivation

Plant bulbs in autumn in loam-based potting compost with the neck and shoulders above the soil surface. Place in bright filtered or full light and water sparingly until in active growth, then water freely and apply a dilute, balanced liquid fertiliser every 2 weeks. After flowering reduce watering as the leaves die off; keep dry when dormant. Pot on every 3-5 years in autumn. See Hippeastrum cultivation for further information

Propagation

Propagate seed as soon as they are ripe. Keep seedlings growing without a dormant period to encourage early flowering, bulbs will take three to five years to flower. Alternatively, propagate by removing bulb offsets in autumn
