1. Hydroponic hyacinth

Hydroponic hyacinth can continue hydroponic culture after flowering. When the temperature gradually rises in June, its leaves will turn yellow and enter the summer sleep period. At this time, the yellow leaves and roots should be cut off together, and then put in a cool and ventilated place to dry for a day or two. After drying, wrap the seed ball with newspaper and put it into the freezer of the refrigerator, and keep the temperature below 10 ℃

When the air cools down in November and enters late autumn, take out its seed ball, put it on the bottle mouth of the container, and add water to a centimeter below the root system. Put it in a dark place and take root in about 25 days

2. Hyacinth cultivated in soil

After flowering, the leaves and stems of hyacinth cultivated in soil are cut off, the bulbs are retained, and then the bulbs are buried in the sand. Wait until around July 20, then dig it out and put it in the freezer of the refrigerator and keep it at 4 ℃ for low-temperature germination. After the sprouts grow, they continue to be buried in the sand for development and culture. It can be cultivated in pots in December
