Plants have strong regeneration ability, so it is not necessary to pay special attention to the length of pruning when pruning plants. As long as the main branches are not trimmed, as long as they are flowering branches, they can be cut off.
2. Pruned branches
Many people don't know what can and can't be cut when cutting plants. When pruning this kind of plants, as long as they have blossomed, cut them all off. Another place that needs pruning is that after flowering, there will be some blooming flowers. These flowering branches don't need to wait for all the flowers to wither, but they can be pruned after flowering.

cultivation techniques
1, planting
(1) Potted jasmine flowers should be watered every morning and evening in summer. If the air is dry, it needs to be supplemented with water spray; During the winter dormancy period, it is necessary to control the amount of watering. If the pot soil is too wet, it will cause a large number of rotten roots or jasmine flowers to multiply by cutting, layering or dividing plants.
(2) The cuttage propagation of Jasmine was carried out from April to10. Select mature 1 year branches, cut them into cuttings with more than two nodes, and remove the lower leaves. They are inserted into a half-muddy bed, covered with plastic film, and maintain high air humidity, which takes about 40 ~ 60 days to take root.
(3) layering propagation of jasmine: select long branches, cut them gently at the lower part of the nodes, and bury them in a small basin filled with sand and mud, and keep them moist frequently. They will take root in 20-30 days, and then two months later they can be cut from the mother plant to form seedlings and planted separately. Apply pancake fertilizer once a week during the growing period. After changing pots in spring, we should always pick our hearts and shape them. Cut it again after flowering to help sprout new branches, so that plants can be neat and robust and bloom vigorously.
2, light and temperature
The first frost enters the greenhouse every year and overwinters at 5 ~ 10℃. Freeze to death below 5℃, and die easily below 0℃. The optimum growth temperature is 20 ~ 25℃. After Grain Rain in spring, we should move out of the greenhouse. Before going out, you should exercise gradually in a sunny place indoors and go out slowly. After leaving the house, it should be placed in the leeward and sunny place, and then let go of management after adapting to the outdoor environment.
3. Water and fertilize
(1) The watering principle of jasmine is "if you don't do it, you must water it thoroughly". Pour it after filling 1 time. According to the weather conditions in spring and autumn, 1 water is usually poured once every 2 to 3 days, and water can be sprayed every day to keep the air moist. Spray water 1 time every morning in summer, and water 1 time after 4 pm. Reduce the amount of watering in the greenhouse in winter, otherwise the roots will rot easily.
(2) Molly likes fertilizer. 1 month later, you can water with alum fertilizer. With the increase of weather and temperature, the growth potential of plants is enhanced, and the concentration of fertilizer and water can be gradually increased. Dry fertilizer can be applied in rainy season. Phosphorus and potassium fertilizer can be applied topdressing before and during flowering to promote flower reproduction and fragrance. Top dressing after each flowering 1 time. Stop topdressing at full flowering stage. Stop fertilizing after entering the house in winter.
4, plastic pruning
Jasmine can be pruned in March. First, dense branches, dead branches, weak branches, cross branches, etc. Prune, and then cut the remaining branches short, and the length of the remaining branches is 15 cm, which promotes the growth of new branches and is beneficial to flowering.
