Watering, pruning, propagation, and repotting details from plant data
Keep the soil consistently moist during the growing season, but not waterlogged. Reduce watering significantly in winter when the plant is dormant. Ensure good drainage to prevent root rot, especially in pots.
Remove spent flower stalks after blooming to prevent seed formation and conserve energy for the bulb. Cut back yellowing foliage in late autumn once it has died back naturally.
This helps prevent disease and tidies the appearance.
Propagate from bulb offsets separated during repotting in early spring. Seeds can also be sown fresh in autumn or spring. Division is the most common and successful method for home gardeners to maintain desirable traits.
Repot lilies every 2-3 years or when the bulbs become crowded. The best time is in early spring before new growth emerges or in autumn after foliage has died back. Use a well-draining potting mix.
