Plant bulbs in the fall, point up, 4 in. (10 cm) deep and about 4 in. (10 cm) apart. Choose full sun or light partial shade, then water thoroughly after planting. In spring, keep the soil slightly moist when rain is insufficient, without allowing water to stagnate. A thin layer of mature compost supports growth; avoid nitrogen-rich fertilizers. Group the four bulbs for a more visible effect. When growing in containers, use a deep pot with clear drainage holes and protect it from repeated freeze-thaw cycles. After flowering, remove faded spikes if you do not want seed formation, but allow all leaves to yellow completely. They replenish the reserves necessary for the next flowering. Reduce watering during summer dormancy and mark the location to avoid disturbing the bulbs. Divide a dense clump after the foliage has dried, then quickly replant firm bulbils. Ornamental bulbs are not for consumption and can irritate the skin; keep them out of reach of children and animals and wear gloves if necessary.
