Generally speaking, if you want to continue planting after its flowers wither, you can cut all the branches of the hyacinth's sucking flowers, leaving only a few leaves. When the temperature gradually warms up, its leaves will fall off naturally. At this time, we should not water the seed ball. Then dig out its seed ball, wrap it with a clean cloth or newspaper, and plant it before next winter. If you don't want to use it for cultivation, you can also use it for hydroponics.
It can be replayed, but it's better to choose a larger ball, because the chance of the hyacinth's replaying is also smaller. Especially in hydroponics, the ball must be large and full. The preserved ball can be planted in November next year. But the newly planted hyacinth flowers are far less vigorous than those in the first year, and the flowers are not so good-looking, so most people throw it away after having a flower.
