Though they will tolerate full sun, Helleborus like shady sites with moist but well-drained soil rich in organic matter. Mix in some good organic matter to poor or heavy clay soils. Woodland setting are perfect. Plants will form colonies if flowers are not removed and seeds allowed to form.

Pruning is only necessary to remove damaged or discolored foliage or to deadhead spent flowers. The best time to prune the foliage of Helleborus is early to mid winter, before plants begin to flower. Flowers can be removed after the fade. If left on the plant seeds will drop and form colonies.

I feed Helleborus in mid Fall with a well-balanced flower or plant fertilizer containing all three essential nutrients (NPK: Nitrogen, Phosporus and Potasssium) to help give the plants a boost before flowering in winter.

I have over 20 varieties of Helleborus growing in woodland and shade gardens and have seen no serious insect or disease problems. Constantly soggy soil could cause problems with the roots.
