1. Pruning

After flowering, the branches and leaves gradually withered and yellow with the increase of temperature, and began to enter the dormancy period. Cut off the flower stems and leaves of plants entering dormancy. The plants cultured by hydroponic method shall be cut off together with the root system, and only the flowers and leaves on the upper part shall be cut off by soil culture method

2. Cryopreservation

Take out the treated bulb before high temperature in summer and dry it in a cool place. After drying, wrap the bulb with newspaper and put it in the refrigerator refrigeration layer. Store it at about 4-5 ℃, and pay attention that the temperature should not be lower than 0 ℃

3. Replant

After the weather turns cold in November, take out the preserved bulb roots and plant them in soil or water again. For planting by soil culture method, as long as the bulb is buried in the soil, the root tip is exposed, placed in the shade for about 1 week, and can be cured normally; The hydroponic method is to put the plant on the top of the bottle, 1cm away from the water surface, and then put it in a cool place to promote its rooting

4. Precautions

Hyacinth plants born in the next year may shrink to a certain extent, because the bulbs have degenerated. Generally, the bulbs can bloom in three years, but it is difficult to bloom in the fourth year. If you need lush flower branches, it is suggested to buy new bulbs directly in the second year
