1. Cold-tolerant varieties can be planted in the south and the Yellow River basin, but indoor potted plants should be used for wintering in cold areas in the north. It can be planted after defoliation and before germination in spring. In order to improve the survival rate, we should avoid damaging the root system and transplant with soil balls. The ground should be planted in the leeward and sunny places. Potted soil with 3 parts humus soil, 3 parts garden soil, 2 parts river sand and 2 parts decomposed fertilizer was selected. Watering after planting 1 time. Keep it in a cool place, and move it to the sun for normal management after the growth resumes.

2. Light and temperature like warm and sufficient light. Except for apricot varieties, it is generally resistant to-10℃ except -25℃. High temperature resistance, can grow at 40℃. It grows best in the area with annual average temperature 16 ~ 23℃. Very sensitive to temperature, it blooms when the average temperature reaches -5 ~ 7℃ in early spring.

3. Pay attention to watering during the growth period of watering and fertilization. The soil in the basin should be always wet, and it can neither accumulate water nor be too wet or too dry. The principle of watering should be mastered. Generally speaking, water less when the temperature is low on cloudy days, or water more. You can water it twice a day in summer, once a day/kloc-0 in spring and autumn, and dry it thoroughly in winter. Fertilization is also reasonable. Before planting, base fertilizer should be applied and a small amount of potassium dihydrogen phosphate should be added. Before flowering, 1 potassium dihydrogen phosphate and 1 cake fertilizer should be applied to supplement nutrition. In June, 1 times compound fertilizer can be applied to promote flower bud differentiation. After defoliation in autumn, apply organic fertilizer 1 times, such as decomposed manure.

4. Pruning pruning time can be carried out within 20 days after flowering. Give priority to with natural tree, cut off cross branches, erect branches, dead branches, too dense branches, etc. And cut short the side branches to promote the flowers to bloom. After potted plum blossoms are put into pots, they should be cut again to lay the foundation for bonsai. Plum piles are usually used as scenery to graft plum blossoms in various postures. Keep a certain temperature, and you can see plum blossoms in full bloom during the Spring Festival. If you want to blossom on May 1, you need to keep the temperature at 0 ~ 5℃ and a humid environment, move out in early April and keep it in a sunny and well-ventilated place, so that you can see the flowers around May 1.

5. flowering control potted plum blossoms are generally for family viewing. After defoliation in winter, keep it indoors at 0 ~ 5℃, gradually raise the temperature to 5 ~ 10℃ after New Year's Day, fully receive sunlight every day, and often spray water on branches, and the humidity of water should be close to room temperature.
