Likes warm climate, has certain cold tolerance, and the flowering period is very sensitive to climate change. Mei likes high air humidity, but avoids heavy rain during flowering. Plum blossoms can also grow well in areas with annual rainfall 1000mm or a little more, which are not strict with soil and are relatively barren. It can also grow normally in weak alkaline soil. According to the experience in the south of the Yangtze River, when planted in gravelly clay and gravelly loam, plum blossoms flourish, flowers are strong and leafy. Active tree species, like sunshine and good ventilation. It is a long-lived tree species.

1. Planting

Can be planted in the south, cold-resistant varieties can also be planted in the Yellow River basin, but the cold areas in the north should be planted indoors. 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. After planting, water plum blossom 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

I like warmth and plenty of 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. If it encounters low temperature, the flowering period will be delayed, and if it encounters low temperature, the flowering period can be extended. The growing season should be placed in a sunny and well-ventilated place. If it is in a cool environment with insufficient light, it will grow thin and bloom sparsely. Don't enter the room too early in winter, and it is advisable to1late October 165438+ to enter the room so that the flower buds can differentiate through the vernalization stage. In winter, it should be placed in a sunny place indoors and the temperature should be kept at about 5℃.

3. Water and fertilizer

Pay attention to watering during the growth period, and the soil in the basin should always be moist, so as not to accumulate water, 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.

Step 4: plastic trimming

Pruning time of ground planted plum blossoms can be carried out within 20 days after flowering. Prunus mume with natural tree shape, cut off horizontal branches, straight branches, dead branches and over-dense branches. And cut off the side branches to promote the flourishing of flowers. 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.
