Every year in winter, I grow hyacinth bulbs in water. Usually, they start to bloom at the end of December, and the flowers stay until the end of February. Once they are done, I do not throw away the bulbs. I wait for spring and plant them in the ground. They will not bloom again in the same year, but they will bloom in the next season. While planting, don’t cut the green leaves; some bulbs may not have green leaves, they change into yellow, don’t worry, plant them just like that. In the next season, it will surprise you with big blooms. The pictures below are from our garden. Here is the link to how to grow hyacinth bulbs in water.
