It is mainly because too much nitrogen fertilizer leads to white growth of branches and leaves. In this case, it is necessary to control nitrogen fertilizer, increase the application of phosphorus and potassium fertilizer, promote the propagation of flower buds, and at the same time pay attention to moving jasmine to a sunny and well-ventilated place. And pruning, which grows fast in summer, should be trimmed in time. Pruning the base of potted jasmine to 10cm ~ 15cm will promote most stout new shoots. If the new shoots grow vigorously, they should be removed when they grow to 10 cm, so as to promote secondary branches, make more flowers and compact plant types. After the flowers wither, the branches should be cut off in time to reduce nutrient consumption, which is also conducive to promoting the growth of new shoots, making the branches dense, with more buds and more flowers.
