1、 Seize the opportunity

To prolong the flowering period of flower arrangement, it is best to cut the flowers when they are in bud. At this time, the flowers wither slowly. In addition, pruning should be carried out in the morning. After cutting, it should be inserted into the water immediately, which can greatly reduce water evaporation and prolong the flowering period to a certain extent

2、 Suitable location

It's better to place flower arrangement in a cool place. Don't put it in a place with sunshine. Don't put it near heating and air conditioning in winter, which will accelerate the withering of petals

3、 Regular water change

The water used for flower arrangement must be clean, and it should be changed regularly. When the weather is hot, change the water every day. In cold weather, change the water every 2-3 days, and properly remove the residual flowers when changing the water. In addition, the flower branches should be cut short to keep the flower branch incision in a fresh state, which can absorb sufficient water and prolong the flowering period

4、 Use preservative

Dilute hydrochloric acid and acetic acid can be applied to the incision of flower branches to prevent the incision from becoming rotten. Salt, sugar and vitamin B12 can also be applied to the water, which can not only prevent bacterial invasion, but also improve the water absorption capacity of branches, and the withering of flowers will slow down
