At the end of each flowering, the pruning must be done, even if there is no flowering in that year. At the end of the flowering period (about the end of February), from 2cm to 3cm at the base of the annual branch, all the new branches above the annual branch shall be cut off, and at the same time, the disease and insect branches, thin and weak branches, disordered branches, etc. shall be cut off, so that a lot of new branches will be produced during the spring germination.
When the length of new shoots reaches 10-15cm, 1 /3-1 /2 of new shoots and 2-3 times of continuous coring can make the new shoots short and strong, which is conducive to bud formation.
Chimonanthus praecox is a strong positive flower. It can receive full light in the south of Huaihe River without shade. Otherwise, the branches and leaves will grow too long due to the lack of light, which will affect the bud breeding. See if the flowers in your home are stunted by insufficient sunlight, long branches and leaves, and flower bud differentiation.
In order to bloom more, we should apply more P and K fertilizer, bury and apply a small amount of compound fertilizer particles regularly, and control the use of nitrogen fertilizer. Otherwise, more nitrogen fertilizer and less P and K are not conducive to the flowering of pregnant buds. When the family chooses fertilizer, ask about the proportion of various elements, and try to choose the fertilizer with low nitrogen and more phosphorus and potassium before and after flowering.
In its growing season, especially after June, the pot plant should not be watered too much, otherwise the branches will grow violently, which is not conducive to the flower bud differentiation of new branches. In the maintenance management, the pot soil should be kept moist.
Potted wintersweet can spend the winter outdoors in some areas of the south, or on the balcony, as long as the potted soil is not frozen. But in the north, plants need to be moved indoors. After winter, wintersweet has a short period of dormancy time. If the temperature is over 12 ℃, the plant can not fully dormant, it will sprout and shoot in advance, resulting in slender and thin branches in the next year, and it is difficult to conceive flower buds.
