Water Fritillaria lusitanica sparingly during its active growth period in spring, ensuring the soil dries out slightly between waterings.

Reduce watering significantly as the foliage begins to yellow and die back in late spring or early summer. During dormancy, keep the bulbs dry to prevent rot.

Remove spent flower stalks and yellowing foliage after flowering has finished. This prevents the plant from expending energy on seed production, allowing it to store resources for the following year.

Cut back the dead foliage to the ground once it has completely withered.

Fritillaria lusitanica can be propagated by division of bulbs in late summer or early autumn when dormant. Carefully separate offsets and replant them immediately.

Seed propagation is also possible but takes several years for the bulbs to mature and flower.

Repot Fritillaria lusitanica every 2-3 years, ideally in late summer or early autumn when the bulbs are dormant. Use a well-draining potting mix, such as a sandy loam or a commercial mix for bulbs.

Plant bulbs at a depth of about 2-3 times their height.
