Plum blossom is the first of the top ten famous flowers in China. With orchids, bamboos and chrysanthemums, they are listed as four gentlemen, and with pine and bamboo, they are also called "three friends of the old cold". In the cold, before bloom, the world was lonely, and spring came.

Extended data:

Appropriate cold protection measures should be taken in the north in winter, especially pruning and shaping in ground planting. Reasonable pruning is beneficial to control plant type, improve the light condition in crown and promote the early flowering of young trees.

Pruning is mainly based on thinning, and it is best to make it beautiful and natural. When pruning, it is advisable to cut off the branches a little. Overweight can easily lead to excessive growth, which will affect the next year's flowering.

Prune more dead branches, diseased branches and long branches than in early winter, and trim and shape the whole plant properly after flowering. In addition, management should be strengthened at ordinary times, and attention should be paid to intertillage, irrigation, weeding and insect prevention.
