Pruning methods for Chinese roses are very important, as they affect the performance of the roses the following year. Pruning not only updates the plant and controls the shape but also reduces the occurrence of diseases and pests, achieving the purpose of promoting buds and flowers. Chinese roses are very tolerant to pruning, so there is no need for excessive concern.
Basic principles of pruning Chinese roses:
1. Inner branches, overlapping branches, withered branches, and diseased branches are all targets for pruning;
2. Master the timing of pruning: prune or remove flowers after spring flowering, remove sick and weak branches with blind flowers in summer, remove aging branches formed after the hot summer in late autumn (above secondary branches), and implement severe pruning in winter or before germination in spring (except for young seedlings and vines).
Basic operations and precautions for pruning Chinese roses:
1. Master the position of pruning after flowering:
Basic principle - prune the stem about 1 cm above the first complete five leaves below the flower, with flexible control; in spring, it is generally a light pruning method.
2. Pruning with bud removal: For abundant flowering Chinese roses, the pruning should not be too long to ensure the number of flowers, while for large-flowered Chinese roses (cutting roses), leave one strong bud on each main branch after the side buds have germinated, up to three, and remove the rest. For very strong mature large seedlings with sufficient water and fertilizer, they can be不受此限制.
3. Pruning long branches: Vertical branches with vigorous growth are difficult to bloom and should be cut to the height of normal branches; Chinese roses in shady conditions need to improve the environment to avoid vertical growth; incorrect fertilization requires correction of fertilizer type and daily fertilization methods, applying thin and frequent all-element fertilizers.
4. Removing flower branches: For potted Chinese roses, blind flower branches are difficult to grow into strong branches and bloom, so they should be cut from the bottom of the branch as soon as they are found.
5. Different from spring pruning: After autumn flowering, if no more flowers are produced (note: many varieties can bloom twice or more in autumn under favorable climate conditions), implement medium pruning, which is longer and heavier than in spring, leaving 2 to 3 buds on each branch. For branches without buds, leave two young branches on each main branch to prepare for winter dormancy. In areas where Chinese roses do not have a dormancy period (minimum temperature above 5°C), prune according to the spring management method, but control flower production and remove flower buds during low temperatures to rest and wait for spring growth.
6. Severe pruning before spring germination: This is a traditional method, focusing on the selection of pruning positions. The main branches are cut, generally at a height of 15 cm above the potting soil surface, or even lower, but not below the swollen part of the rootstock junction, otherwise it will result in "no剪没" because the branches are completely gone, with no new buds. The purpose of severe pruning: In cold regions, to ensure that the branches are not frozen, to regenerate basal branches and update the main branches, to promote strong side branches, and to reshape the plant. Many rose lovers pay attention to the shape of the plant and can prune severely or heavily at this time, and pinch the top (remove the top bud) before the vigorous growth of spring branches begins to correct the height of all branches (pinch high and leave low, pinch inside and leave outside) to achieve the ideal plant appearance (the most ideal is a hemisphere shape). This requires careful management of water, fertilizer, and lighting, as well as personal time and effort, which is not easy for beginners.
Note: Severe pruning is not a necessary operation. Those who advocate severe pruning need to think and act cautiously: they should consider factors such as variety, growth, season, health, germination ability, and temperature and humidity, otherwise they may regret the "no剪没" situation.
7. Severe pruning in summer: Unless the plant is severely affected by disease, do not perform severe or heavy pruning during the high heat of summer, as most Chinese roses are in a semi-dormant state at this time, with respiration stronger than photosynthesis. The plant is using stored nutrients to survive, and severe pruning can interfere with normal physiological activities, causing almost no transpiration and termination of internal nutrient transport. Latent buds are difficult to germinate in high temperatures, and the plant is easily damaged.
Object control: Normal young seedlings (within 40 cm in height) generally do not need to be pruned, while strong large seedlings and mini Chinese roses have a high tolerance to pruning.
Pruning tools and healing: Use sharp and clean specialized pruning shears for the operation, cut quickly, and make a clean cut. Do not twist剪, as it can easily damage the stem epidermis and cause the plant to become infected with bacteria. Diseased seedlings have poor resistance and should be treated with antiseptic drugs and sealed with wax or a wound healing agent after pruning. It is not suitable to operate in the rain, and the smaller the wound surface, the better.
The above pruning methods for Chinese roses are a bit of green plant experience, hoping to bring you help in life!
