Chimonanthus praecox is a woody plant with strong germination and many branches. It should be pruned frequently to promote its growth and flowering. Spring pruning can be combined with changing pots, leaving 20cm for each branch, cutting off the upper branches, and properly thinning out the branches that are too dense and too thin. When the new branches grow to about 10 cm in summer, they should be pitted to make the branches strong and the crown perfect. Pruning blooming Chimonanthus praecox should start with seedlings. When the seedlings grow to 20-25 cm long, cut off the top, leave 3-5 branches as main branches after germination, and pick the core when the main branches grow to 10- 15 cm to promote the formation of thick branches and flower buds. The following gardener uncle introduces several pruning methods of potted wintersweet. Pruning method of plum blossom 1 Single stem pruning and pruning method 1. First year pruning and coring methods. One-year-old seedlings were selected as the main culture in the first winter, and a short film of about 1750px was left. Leave a bud under the cuttage with the direction opposite to that of the lower interface bud as the trunk extension branch, and remove the remaining branches on the cuttage trunk as the auxiliary branch. When crowns are formed, they become thinner. In order to make Chimonanthus praecox bloom before molding, short branches and middle branches on the trunk should be pruned in summer to promote branching. Prune the heart every 3 pairs of buds, sometimes even when 1-2 pairs of buds appear. Summer pruning usually stops after March to June and July to August. Pruning method of Chimonanthus praecox in the second year. The next winter, lengthen the trunk, cut the branches short, leave a bud under the incision and change direction. In order to prevent the lateral branches under the cutting mouth from growing too vigorously and competing with the central branch, two pairs of lateral branches under the cutting mouth bud must be cut off. The left branch is only used as an auxiliary branch, which should not be cut short, but should be long and slow. In summer, coring can control the growth of lateral branches and promote the growth of main branches. 3. The pruning method of the third year The winter of the third year is the same as that of the previous year, except that the top of the trunk is cut off to prevent it from elongation and growth again, and three staggered buds are left under the incision as the main branches. In order to make it continue to stretch, after the branch is extracted, the pruning tip of 15~500px is left according to the growth intensity, and a bud is left at the incision to change the direction of the new branch and weaken the growth. If there are upper and lower opposite buds, cut a section together with the mother branches in summer, leaving the square buds as branches. In the range of about 750px between the three main branches and the trunk, the oblique branch is selected to cut off the top and leave a lateral bud as a lateral branch. 3. The side branches on the main branch are arranged on the corresponding side to avoid overlapping. For the remaining branches on the main branch, cut off the buds at the base of the strong leaves again; The medium-long weak branch leaves 1~2 buds short, and two medium-short branches grow in the second year. Pruning methods of potted Chimonanthus praecox in the fourth and fourth years The pruning method in the fourth year is the same as before, except that the second branch is in the opposite direction. Second, the three main branches pruning and shaping method According to the concise pruning method of flowers and ornamental trees, the three main branches are cultivated and then divided into side branches. Leave 3~5 short nodes on the flower branches, and the new branches will grow to 10 cm, thus topping the heart and promoting flower bud differentiation. Three-three pruning and shaping method: three main branches are directly sent out from the root. Four. In the first year of multi-stem pruning and shaping method, more than three thick branches that are straight out of the root and evenly distributed around are taken as the main trunk, and they are cut short to leave 3~5 nodes long. In the second year, the main branches should be properly bundled into clusters to avoid overlapping and crossing branches. Potted Chimonanthus praecox V. The specific operation of pruning wintersweet tree 1. Chimonanthus praecox has a strong tillering ability, and a large number of clustered branches often grow on the roots, but these clustered branches generally do not differentiate flower buds. Therefore, Chimonanthus praecox should keep the trunk about 30 cm, then cultivate three main branches and then branch out the side branches.
5. Cut off the top of the new shoots in late summer and early autumn, and trim the top of the new shoots in that year to make the buds of the middle and lower branches full and prepare for winter flowering. Generally, the new shoots of 10cm leave 4~5 pairs of buds. 6. Treatment of potted Chimonanthus praecox For potted Chimonanthus praecox, two pairs of buds are left on the annual branches after flowering, and the rest are all cut off.
