One-or two-year-old flowers are mainly shaped by picking leaves and removing buds. In the process of growth, the leaves are too dense to be ventilated, or the diseased leaves die, so they should be pulled out in time. In order to ensure the flowering quality of the main buds, too many lateral buds can be eliminated, or buds with similar sizes can be kept to adjust the flowering speed and make the whole plant bloom neatly. Some lianas need scaffolding and binding. The annual or biennial flowers used for cutting flowers need to be set up in sheds or nets to prevent lodging.

Picking the heart is to pick the top bud or branch tip. Picking the heart has three functions: first, it can make the plants cluster, clusters are full and round, and there are many flowers; Second, it can promote plant dwarfing; Third, the flowering period can be prolonged. Generally, you can pick the core 1 ~ 3 times. Such as zinnia, Petunia, marigold and so on. But if there are flowers on the main stem and large species are not suitable for picking, such as cockscomb.
