Potted plum blossoms should be kept in a ventilated and sunny place, too dense or blocked by the environment, so that the plants are tall and thin, and the buds in winter are full and thick, colorful and graceful. If we control the tree shape and promote the early flowering of young trees, we need to trim and shape them in time.

The buds of plum blossoms are formed on the new branches every year. Generally, when the seedlings grow to 25-30 cm, the top is cut off, and after germination, the top 3-5 branches are left as the main branches. When the branches grow to about 20 cm, pick the heart to help the buds to be full.

In the second year, after flowering, leave 2-3 buds at the base and cut them again. Pay attention to the direction of cutting buds when cutting, and choose outward buds and inward buds. After germination, cut off cross branches, over-dense branches and overlapping branches. Because straight plum leaves have no posture, regular plum leaves have no scenery, and dense plum leaves have no posture, they should be trimmed according to the principle of "sparse, dense and curved" without affectation.

Potted plum blossoms should be pruned in early spring every 1-2 years, and the pots and soil should be changed. If potted plum blossoms bloom in the Spring Festival, they will be naturally dormant outdoors after defoliation in winter, and then moved to the sunny place in a warm room after New Year's Day, and the room temperature will be maintained at 8- 12℃. Sprinkle water on the branches every day, keep the pot soil moist, color the buds, and then raise the temperature to 1 5-20℃, so that flowers can bloom in the Spring Festival.

Matters needing attention in plum blossom bonsai

1, plum blossom has low requirements on soil, and generally neutral soil can grow, but potted plum blossom should choose loose and fertile nutrient soil because of limited basin soil. Nutritious soil is a culture medium which is composed of 4 parts of edible residue, 4 parts of accumulated miscellaneous fat soil and 2 parts of coal ash soil. After flowering, the soil is changed once a year, and then it is placed in the shade for a week, and then it is transferred to normal maintenance.

2. Plum blossoms are sensitive to moisture. If the basin soil is too wet for a long time, it is easy to cause rotten roots. So control the watering. When the new branches grow to 20 cm, attention should be paid to controlling watering, controlling excessive elongation of new branches and promoting flower bud differentiation. But water it once a day in summer, keep the soil moist according to the soil conditions in autumn, and use less water in winter to make the soil dry.

Plum blossoms don't like big and fat plum blossoms. When the branches and leaves germinate, it is necessary to have sufficient fertilizer and water, and apply organic liquid fertilizer 1 to 2 times a month. When the new branches grow to 5 cm, a thin layer of fertilizer should be applied to promote the growth of the branches. In late summer and early autumn, fertilizer and water should be applied to the decomposed cake once, and phosphorus and potassium fertilizer should be applied to promote the formation of flower buds. Spraying 1 to 2 times of potassium dihydrogen phosphate after flower bud differentiation is beneficial to the growth of plum blossom.
