Hippeastrum or Amaryllis is a flower that blooms in the winter. After the plant dies, rather than throw the bulb away you should keep them to flower again next year. When the flowers have faded, cut off the thick flower stalk at bulb level. The foliage should be allowed to develop and grow over the spring and summer, and to encourage the bulb to swell keep the compost moist at all times and feed weekly with a liquid feed such as Phostrogen. Only when the leaves naturally start to die down in summer should you stop watering and allow the bulb to dry out. By then it will be plump and contain embryo flower buds for next spring.
