1. Planting is mainly ground planting, and there are also a few potted plants. Plant before germination in spring or when leaves fall in autumn. In Beijing area, it is suitable for planting in sunny environment. The sleepy cherry blossom is a shallow-rooted tree species, and the planting hole should be large, but not too deep. The soil needs a slight acidity. Planting is easy to survive, but blood should not damage the root system when transplanting, and it is best to plant with soil balls. Cut off some branches after planting to reduce water evaporation in plants. Potted plants should be mixed with humus soil, garden soil and river sand, and appropriate amount of decomposed manure and cake fertilizer should be added. Water after planting. 2. The suitable temperature for light and temperature growth is 18-20℃, and the ground and potted plants should be placed in sunny places. In winter, potted cherry blossoms should be placed in the leeward, sunny and well-lit place after entering the room, otherwise they will not grow well. The Central Plains can safely overwinter in the open air. Young Qu and newly planted seedlings in Beijing need to take cold-proof measures to adapt gradually, and the planting environment should have a certain humidity, which is conducive to the normal growth and development of cherry blossoms. When the newly planted plants grow stably, their adaptability to low temperature gradually increases, that is, their cold resistance increases. 3. Water and fertilize after planting. The water is permeable, so don't fertilize first. In order to make cherry blossoms flourish and colorful, organic fertilizer can be applied after falling leaves in autumn and before germination in spring. Water the trees often, and water them often when you are young. If it is found that the plant is not growing well or the leaves are yellow, 500 times ferrous sulfate solution can be added and applied to the tree hole with water. Potted cherry blossoms can be fertilized with dilute water several times in summer, generally every 7 days 1 time. 4. The natural tree shape is the main shape of pruning and cutting flowers, and it does not need to be deliberately carved. Cut off dry dead branches, weak branches, long branches and over-dense branches, and cut off the remaining branches appropriately. Potted cherry blossoms can be shaped according to personal hobbies, requiring overall tree posture and pot prevention, too small and too high, and the proportion is out of control. Pruning time should be after flowering, short pruning will promote more lateral branches, which is beneficial to flowering in the next year: 5. If you want to see flowers in the Spring Festival, you can move the potted plants indoors 40 days in advance, put them in a sunny place, keep the room temperature at 15-20℃, and spray water frequently around the potted plants to keep them moist, so that you can keep the potted soil dry and see flowers in the Spring Festival.
