Martagon Lilies require consistent moisture during their active growing season from spring through flowering. Water deeply once or twice a week, especially during dry spells, ensuring the soil remains evenly moist but not waterlogged. Reduce watering significantly as foliage begins to yellow and die back in late summer, leading into their winter dormancy. Avoid overhead watering to prevent fungal issues.

Martagon Lilies can be propagated by seed, though this is a slow process taking several years to flower. More commonly, they are propagated by division of offsets from mature bulbs in late summer or early autumn after the foliage has died back. Scale propagation, where individual scales are removed from the bulb and planted, is also an effective method for increasing stock.

When grown in pots, Martagon Lilies should be repotted every 2-3 years, or when the bulb has outgrown its container. This is best done in autumn during dormancy. Carefully remove the bulb, gently separate any offsets, and replant in fresh, well-draining potting mix, ensuring the top of the bulb is covered by about 10-15 cm of soil.
