Planting: it can be planted in the south, and cold-resistant varieties can also be planted in the Yellow River basin, but it is suitable to be planted indoors 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.
Light and temperature: I 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.
Watering and fertilizing: Pay attention to watering during the growth period, keep the soil moist at all times, without water accumulation, neither too wet nor too dry, and master the principle of watering after drying. 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. Apply base fertilizer before planting and add a small amount of potassium dihydrogen phosphate at the same time. Apply 1 times potassium dihydrogen phosphate before flowering and 1 times decomposed cake fertilizer after flowering 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.
Pruning: Pruning 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.
Flowering management: 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.
