Hyacinths need a cold dormant period to be able to produce new blooms. Stop watering and let the leaves turn brown. When the bulb is dry you can remove the leaves and store the bulb in a cool place (refrigerator works) for about 8 weeks. Then you can plant it in soil again and start over. See more questions and answers on this page about how to store bulbs and how to get them to rebloom.
