Trim. The 3-6-year-old seedlings of Jasmine blossom most vigorously, and then they will age year by year, so they need to be pruned and updated in time. Before the Spring Festival sprouts, the branches in the last year can be properly cut short, and the base should be kept at 10- 15 cm, so that most stout new branches will appear. If the new branches grow vigorously, they should be pulled out when they grow to 10 cm, so as to promote the secondary branches, which will produce more flowers, compact plaster type and high ornamental value. It should be noted that pruning should be carried out in sunny days, and combining with leaf thinning can remove diseased branches and adjust plants, which is beneficial to growth and flowering.

Fertilize. Jasmine is a plant that shoots and buds many times a year and blooms all year round, so it needs a lot of fertilizer, which is an important guarantee for jasmine to bloom more. Organic liquid fertilizer is the best fertilizer for potted jasmine, but it is best to use decomposed human feces, or human feces mixed with chicken and duck feces, pig feces, bean cakes, vegetable cakes and so on. The most suitable fertilization time is when the soil has just turned white and small dry cracks have just appeared on the soil surface around the basin wall. When the new buds begin to sprout, they can be watered with dilute manure water (the ratio of manure to water is 1: 9) every 7 days 1 time. When flowering is fast, the concentration of manure water can be increased. Water every 3 days 1 time. When the second and third batches of flowers are in bloom, topdressing can be carried out within 1-2 days 1 time due to the suitable temperature, many flowers and vigorous growth. In the future, fertilizer and water will be gradually controlled to prevent plants from growing vigorously and tissues from being tender and difficult to overwinter.

Reproduction uses cutting, layering or dividing plants. Cutting propagation is carried out in April-June and 65438+1October. Select mature 1 year-old branches, cut them into more than 2 cuttings, remove the lower leaves, insert them in a semi-muddy bed, cover them with plastic film, keep the air humidity high, and take root after about 40-60 days. Propagation by layering, selecting long branches, cutting them slightly at the lower part of the nodes, burying them in a small basin filled with sand and mud, keeping moisture frequently, and taking root after 20-30 days. After two months, they can be cut from the mother plant to become seedlings and planted separately. Potted jasmine should be watered every morning and evening in summer. If the air is dry, add water. During the winter dormancy period, it is necessary to control the amount of watering. If the pot soil is too wet, it will cause rotten roots or fallen leaves. Apply pancake fertilizer once a week during the growing period. After changing pots in spring, you should always pick your heart and have a facelift. Observe the lower leaves when pruning after flowering, keep the last place with axillary buds and cut them all off. 2-4 leaves on the upper part of the cut branches are reserved for cutting. Remember that the knotted place is the easiest place to take root, so insert the matrix in the knotted place.
