Requirements: Full sunlight in cooler areas; partial or light shade in warm areas. Soil pH 6.0 to 7.5. Humus rich soil, moist soil. Dry soil may stunt growth. Protect from wind in areas known to be hit by winter storms. Regular watering. Provide low nitrogen feed in the spring. Tidy dead leaves and flowers. Protect from slugs. Propagate: divide every three years to maintain vigor and to create new plants; cuttings in the spring.
Miscellaneous: Can tolerate extreme temperatures and large fluctuations.
When planting Bergenia outdoors it is best to sow out the seeds on the surface in the early spring; it is important to sow out Siberian tea and similar species before the last frost, as it requires this for germination.
If you plan to grow Bergenia indoors first then the seeds should first be placed in moist soil, placed in a plastic bag, and refrigerated for two weeks before shifting to the light.
Growth of Bergenia should then continue at a temperature of 15 to 21 degrees Celsius. It usually takes from one to six months for this garden plant to germinate. Seedlings should then be transplanted outdoors into an area of full sunlight or a lightly shaded part of the garden. Seedlings should be planted at a distance of 30 to 45 cm in moist soil with a pH of between 6 and 7.
Bergenia should be lightly fertilized in the spring, and kept well watered. The use of slug pellets is highly recommend and dead parts of the plant should be removed regularly.
