Plant the bulbs in autumn before the ground freezes, approximately 8 cm (3 in) deep and 5 to 8 cm (2 to 3 in) apart. White Glory-of-the-Snow thrives in full sun to partial shade and prefers light, fertile soil that remains moist in spring while draining well throughout the year. Water lightly after planting, then maintain moderate moisture during active growth. Once flowering has finished, allow the foliage to yellow naturally so the bulbs can replenish their energy reserves. A light application of compost or bulb fertilizer in early spring encourages abundant, long-lasting blooms.
