Huangmei is wintersweet. Chimonanthus praecox is a rare ornamental flower in winter. In order to make wintersweet tree beautiful, quaint, big flowers and full of fragrance, we must pay attention to pruning and shaping. The practical experience is as follows: Chimonanthus praecox branches are stout, pruning-resistant, re-pruning and easy to shape. Its roots and neck are prone to vigorous tillering, except for 65433, some of which can grow outside the crown in that year. Generally, flowers should be pruned in time after withering to remove dead branches, too dense branches, cross branches, pests and diseases. The annual branches are all cut off except for 2 ~ 3 pairs of buds at the base to promote germination and branching. After each new branch grows 2 ~ 3 pairs of leaves, it is necessary to pick the heart to promote the short and strong flower branches and make the plant shape symmetrical and beautiful. Pruning is mostly carried out in March-June and stopped after July. If pruning is not timely, it is easy to produce many branches. Consume nutrition; Poor flower bud differentiation affects flowering.

According to the different ornamental requirements and cultivation methods, the pruning and shaping of cultivated Chimonanthus praecox are very different: Chimonanthus praecox planted on the ground has strong germination ability, and if it is left to grow, its branches will be messy, which will seriously affect the ornamental and flowering fragrance. Therefore, the method of single culture is generally adopted. After planting for one year, select 1 strong branch, dig a hole 50 cm away from the root, apply base fertilizer to cultivate the soil, and cut off all the other branches, which can reach 65,430 branches in a year. We should continue to pay attention to pruning and shaping, and cut off budding branches in the rhizosphere at any time. After 3-4 years, we can grow a tree 4-5 meters high. In the future, we should pay attention to leaving 4-5 nodes on the new branches of the trunk for coring, so that the ramets will flourish and the trees will be full of flowers. We can choose three stout vertical branches as the trunk, prune the sprouting tillers and other branches in the rhizosphere at any time, and pick the heart at the right time to make the trees flourish.

Potted Chimonanthus praecox has the characteristics of vigorous growth and many rhizosphere branches. Potted plants can form grotesque trees after several pruning, so most of them are cultivated into pile-head bonsai; 1 stout central main branch should be selected before going to the basin, and other branches should be cut off from the base, leaving 3 evenly distributed lateral branches upward; And cut off the top of the main branch to make the flower branches grow from these three side branches. In the future, in addition to cutting off the flower branches in time after the flowers wither, we should also trim the over-dense side branches and all tillers at any time, and trim the side branches on the main branches, which should be gradually shortened from bottom to top every time, so as to complement each other and make them patchwork. Pile more soil on the old pimples and keep them moist, so as to survive. Later, the pots were changed year by year to get rid of the bright roots, and a vigorous and ancient tree shape was gradually formed. After plastic arts processing, it can be kneaded into various shapes, such as screen fan type, single type, multi-body type and so on. , can also be cultivated into a knot in one's heart plum. If the old root is Chimonanthus praecox, it can be grafted and replaced with fine varieties.
