Tea plum, also known as small tea plum. The flowering period is from 10 of the current year to April of the following year. It is not only magnificent in color, elegant and elegant, but also beautiful in tree shape and has strong adaptability to tea plums. Like to grow in slightly acidic loose yellow loam, suitable for semi-shady environment, strong cold resistance, and can tolerate low temperature of-10℃. Change the pot every 2 ~ 3 years 1 time. Pay attention to shaping after changing pots in early spring to make them ventilated and transparent. Put it under the arbor in summer and spray water frequently to keep the air humidity. In winter, put it indoors at room temperature above 0℃ for wintering. Specific maintenance measures are:

1, potted plants should choose loose, fertile, well-drained and slightly acidic culture soil. In the north, humus soil or peat soil is suitable as the main culture soil.

2. Fertilization should be light and fully decomposed. If the application of raw fertilizer or concentrated fertilizer will burn the root system, in general, apply dilute nitrogen fertilizer once in February to March to promote the growth of branches and leaves; Applying pancake fertilizer and water once in April ~ May is beneficial to flower bud differentiation; Apply 0.2% potassium dihydrogen phosphate solution once from September to 65438+1October to promote the flowers to be large and colorful. In order to maintain the proper acidity of the basin soil, alum fertilizer can be applied in conjunction with fertilization.

3, watering to keep the soil moist, not too wet. Water should be dry and wet.

4. Tea plum likes humidity, and the semi-cloudy environment is most suitable. Generally, it should be maintained under the shade shed from April to September every year. In summer, strong sunlight will burn leaves and buds, causing leaves to curl, burn and fall off. Even in autumn and winter, too strong light is not conducive to its fertility.

Tea plum, like camellia, needs to be thinned and cut off in time to reduce nutrient consumption. Generally, each branch leaves 1 bud, and the rest is drained of concentrated nutrition, so that the flowers are bigger and the colors are more. Cutting off the residual flowers in time can not only maintain the beauty of the plant, but also be conducive to the germination of new branches. In addition, it is advisable to change pots 1 time every 2-3 years after flowering. In addition to adding new culture soil and supplementing nutrition, the basin should be properly trimmed and shaped to make it ventilated and transparent.

The propagation of tea plum can be carried out by cutting, grafting, layering, sowing and other methods, and cutting propagation is generally used. Cutting is carried out in May. Cuttings are selected from strong branches of mother plants that have been used for more than 5 years, with heels at the base, and redundant leaves at the lower part are cut off, leaving 2-3 leaves. You can also cut short spikes of single bud into cuttings and insert them with cuttings. The bed should be shaded, take root after 20-30 days, and gradually transmit light in the morning and evening. The seedlings can be transplanted or potted in the second year.
