1. Prepare a container with suitable height and size, cut the bottom of the gypsophila with scissors, and cut off the leaves and shoots at the bottom. Finally, put it in a container and raise it with a little water. The water level should not be too high. When tap water is used, it should be dried for a period of time, and chlorine gas should be released before adding it to the container.

2. Trim the rotten and soft parts at the bottom of branches every day, clean the containers and replace them with clean water. Don't throw the bouquet away until it turns yellow and dries.

3. If you have the conditions, you can buy a better fresh-keeping agent for flowers, which has a good fresh-keeping effect and can keep fresh for a long time. If there is no ready-made preservative, you can also add a small amount of salt or vitamin C to the water as a preservative, which can prolong the storage time.
