White Hellebore prefers consistently moist soil, especially during its active growing season. Water deeply when the top few centimeters of soil feel dry. Avoid waterlogging, which can lead to root rot.

Reduce watering in late autumn and during winter dormancy.

Pruning is generally minimal. Remove dead or damaged foliage in late winter or early spring before new growth emerges.

Cut back spent flower stalks after blooming if desired to prevent self-seeding, though this is not strictly necessary for plant health.

Propagation is primarily done through seed, which requires a period of cold stratification. Sow seeds outdoors in autumn or stratify them indoors in a moist medium in the refrigerator for 2-3 months before sowing.

Division of mature clumps is also possible in spring.

White Hellebore is a slow-growing perennial and does not require frequent repotting. Established plants are best left undisturbed.

If repotting is necessary due to container size or to rejuvenate the plant, do so in early spring just as new growth appears.
