Pruning period is divided into winter pruning, spring pruning and post-flowering pruning. Pruning in winter and spring is carried out after the leaves of roses fall and before germination. Cut off the vigorous branches properly to ensure the yield of flowers. The branches or lots of rose with poor fertilizer and water conditions, weak growth and many old branches should be cut again appropriately to achieve the purpose of concentrating nutrition, promoting the germination of new branches and restoring growth.

Prune flowers after harvest. It is mainly used for thinning honey branches and horizontal branches from branches with vigorous growth and dense branches, but it should be lightly cut, otherwise it will cause imbalance between underground and ground, resulting in adverse consequences.

Potted roses should be pruned again after winter. When the temperature rises in March next year (northwest Jiangxi), new buds will sprout. When the new shoots grow to 4 cm-5 cm, according to the size of the flowerpot, 3-5 new shoots will be formed in each pot, and all other new shoots will be removed, so that these new shoots can grow and bloom healthily.

After the initial flowering period of potted roses, in order to make potted roses grow strong, beautiful in plant shape and gorgeous in flowers, besides keeping up with the management level, especially the fertilizer and water conditions, the key technology is pruning at flowering period. The purpose of pruning at flowering stage in China is to concentrate nutrients and reduce unnecessary nutrient consumption. Not only to open this crop of flowers, but also to promote the growth of strong new buds and open the next crop of flowers. Therefore, the key points to be paid attention to in pruning are: wiping buds before flowering and pruning after flowering.

Potted roses should not have too many buds before flowering. Generally, 2-3 buds are left on each branch after pruning. When the new bud grows to 3 cm-4 cm, 1 flower bud is usually left on the branches, and 65,438+0-2 more flower buds can be left on the stout branches to concentrate nutrition and promote the flowers of this crop to be large and bright. Moreover, only 4-6 flower buds can be left in the whole pot of Chinese rose, and they should be evenly distributed, and all other new buds should be wiped off. ?

Pruning after flowering: After each crop of flowers is over, the flower branches should be pruned from 3-5 leaves at the base in time, and the cut parts should pay attention to the outward buds of about 1 cm. At the same time, it is necessary to cut off the diseased branches, dead branches, lateral branches and internal branches, so as to concentrate nutrients, promote the development of Zhuang new technology, make potted roses compact in plant shape, concentrate flowers, and make flowers bloom big and bright.

Roses belong to shrubs. After cutting flowers, with the passage of time, the growth potential of the main branches gradually weakened. Therefore, it is necessary to weed out the old main branches at regular intervals and cultivate new main branches at the same time to maintain the growth potential and plant yield. When pruning, first cut off the old branches with weak growth potential, and keep 3 ~ 5 youngest main branches per plant, and then cut the remaining main branches to the height of 120 cm. Promote the growth of new main branches at the base of plants.
