Plum blossom potted plants are mainly plum blossoms. Plum blossoms potted in September are more delicious-10. Choose grafted saplings that have been cultivated in the field for 2-3 years and have strong roots, and flowers can be seen in the same year after planting. In order to make a plum blossom shape, the top can be truncated at a height of 20-30 cm, and 3-4 new buds can be left at the top as the main branches for culture. Plum blossoms are suitable for growing in loose and fertile soil. Potted soil is generally composed of 2 parts humus soil, 2 parts weathered river mud or paddy soil and 6 parts fine sand soil (dry manure or cake fertilizer can also be slightly mixed into the culture soil). After the basin is put on, it should be watered twice continuously and maintained in a sunny place. This flowerpot is better than ordinary pottery pots. When you are in bloom, move it into a teapot to watch.

② watering

Plum blossoms are sensitive to soil moisture. When watering, you should master the principle, not not not watering, but watering thoroughly. When watering and drying, avoid getting too wet. If the soil contains too much water, the leaves will turn yellow and fall off. If green leaves are found to fall off, it is because the soil is too dry. In order to make plum blossom have more buds, when the new branches grow to about 25 cm, we should do "drought treatment", that is, stop watering for a short time, commonly known as "water harvesting" treatment, so that the leaves of the plants will become warped due to lack of water and the branches will wilt slightly, and then water them with small water to "slow down the seedlings". The amount of water in "Xiaoshui" is about 6-70% of the usual watering amount. After several days, the water was stopped for a short time, and repeated several times, forcing the new buds to stop growing and the secondary branches to germinate, commonly known as "fixing the head", but slowly "discharging water" and gradually returning to normal watering. The purpose of this "water harvesting" can control the growth of new shoots from being too long, at the same time, it can also concentrate the nutrition of plants, increase the growth of flower buds, and achieve the effect of more flower buds. However, it should be noted that due to the long air-drying time of the basin soil, a small amount of water should be poured first to make the roots slowly absorb and gradually restore vitality. You must not water it immediately, it will cause a lot of fallen leaves. The fallen leaves of plum blossoms will directly affect the buds during pregnancy, so pay special attention. Plum blossoms like water, but they are not resistant to waterlogging. There is much rain in spring, which tends to make the branches flourish and the flower buds decrease. The Huangmei season is the time to breed flower buds, and the pot soil should be slightly dry. At this time, too much water will make the branches grow slender, and even the yellow leaves will fall off, which will affect the flower buds. Suitable for high temperature and high humidity in summer, water it once from 8: 00 am to 4: 00 pm. Pay attention to pouring water into the side basin after heavy rain to prevent water from accumulating in the basin. In autumn, we should gradually reduce the amount of watering and keep it moist. Generally, water it once every morning, 1-2 days. After the first frost leaves fall, the buds have grown up and can be watered every other day or every few days. Water less between flowering and leaf exhibition.

③ Fertilization.

Fertilization of potted plum blossoms can be done once in spring (70% human excrement, 30% water) except for the base fertilizer when changing pots, and it must be "backwater" the next day after application. After this heavy fertilization, the requirements of branch germination and leaf germination in spring can be met, and fertilization is not needed, especially when the bud grows to about 5 cm, otherwise it will easily lead to excessive growth of branches and the harm of aphids. In the middle and late May, light topdressing 1-2 times (30% human excrement and 70% water) can be applied to promote flower bud formation. Early August is the second rooting period. At the same time, in order to promote flower bud hypertrophy, topdressing can also be done once (30% human manure 70% water). At the beginning of September, the new roots of plum blossoms have matured. In order to make the flower buds strong, a small amount of phosphate fertilizer can be applied.

When the buds are ready to be released, a small amount of nitrogen or phosphorus and potassium fertilizer should be applied topdressing. The sources of fertilizer are: bean cake water, peanut cake water (poured on the pot soil) and dried chicken manure (scattered on the pot soil or buried at the edge of the pot).

④ Pruning

Plum branches should be sparse and not complicated, and they should be pruned in time if they are too dense. Flower buds form on the new branches of the year. Among the new branches, the short branches and the middle branches bloom more, and the long branches often do not bloom. Therefore, pruning can be used to promote more new branches. Young plants in the first pot can choose to keep 2-3 strong branches and cut them short by about 20 cm. All the remaining branches can be cut off from the base, so that new branches can grow on the short branches. If there are long branches, thin branches, diseased branches, overlapping branches and dense branches in the growth process, they should be cut off in time. Trimming should be combined with shaping. Plastic surgery should keep the natural shape according to the growth potential of plants, and pay attention to horizontal, oblique, leaning, bending, ancient, elegant, light, sparse, poetic, sparse and dense. After the flowering period, except the main branch is 20 cm, all other branches are cut off at about 3 cm. After flowering, the upper part of the branch is cut off, and 3-4 leaf buds are left at the base, so that these leaf buds become new shoots and then flowering branches are formed.

⑤ Turn over the basin.

Potted plum blossoms should be turned once a year, and pots with a diameter of more than 30 cm can be turned over for two years. After the flowers wither, the pots can be turned over from the end of March to the beginning of April. When turning the pot, first take the whole plant out of the pot, shovel a part of the original soil slightly, combine with pruning, cut off the decaying old roots and poorly growing fibrous roots, and then put the roots in the sun for about two hours to dry their surfaces. According to the size of the plant, the flowerpot is slightly larger than the original one. Add new soil to the basin and apply appropriate amount of bean cake, horseshoe or sheep hoof shell as base fertilizer. After putting the basin away, thoroughly pour it with fresh water stored in the jar, and then put it in a sunny place with ventilation.

Potted plum blossoms can be moved to an ice-free room for the winter after falling leaves in winter. If you want to promote early flowering, you can move it into a low-temperature greenhouse around 10℃ 60-70 days before the expected flower viewing, and then you can bloom. At the same time, pay attention to watering and get more sunshine.
