Christmas Roses, Snow Roses and Lenten Roses all happily grow and thrive well without requiring a great deal of maintenance if planted in the right spot. Hellebores do not tolerate being transplanted. Also avoid digging the soil around them. The leaves that have fallen off deciduous trees provide a layer of mulch in winter; simply leave them lying on the ground. They form a layer that activates soil life. A bark mulch cover can be applied as an alternative. Horn shavings and compost can be used as organic fertilizers. Remove any older or brown hellebore leaves.
With Lenten Roses, it is recommendable to remove all leaves before flowering starts in December and January (when budding stems are approximately 10 cm in height). Removing dead flowers from hellebores is normally not necessary; the slightly pink or green tones taken on by the flowers as they fade actually extend the flowering season in winter. After flowering, remove the seed pods before they open to avoid overcrowding; offspring plants normally don't flower well and might suppress the original plants.
If you are planting Christmas Roses and Snow Roses in planters, tubs or window boxes, make sure the containers you are using are thick-walled to prevent the soil from easily freezing. They should also be frost-proof.
After planting, make sure that there is an adequate supply of water. Plants in containers should never be allowed to completely dry. Also, take care to avoid waterlogged conditions.
