Training Methods and Techniques for Pruning Climbing Roses
Sharing the pruning methods and techniques for climbing roses and related content on the maintenance precautions of green plants will certainly help you. Let's learn about them together!
Climbing roses, also known as trailing roses, have a rich variety of colors and a strong fragrance, making them highly ornamental. Regular pruning of the plants is necessary during cultivation, with different methods depending on the different stages. I will introduce these methods to you in detail below.
1. Pruning Time
Climbing roses need to be planted for more than two years before pruning can be done, usually in late winter to early spring. In the north, pruning is done after the leaves fall, while in the south, it's done in the coldest months, typically between December and January. Pruning can also be done based on actual conditions; pruning before and after flowering helps in the rational use of nutrients, preventing waste.
2. Daily Pruning
Climbing roses grow tall and quickly, with branches and leaves that can become tangled, affecting their shape. Regular pruning is necessary to keep the plant looking good. During daily pruning, overlong vines and tangled thin branches are cut to achieve a more reasonable distribution for the desired ornamental effect. Additionally, withered and diseased branches are removed to retain nutrients and prevent pest and disease damage, allowing the plant to grow healthier and stronger.
3. Pruning Before Flowering
Climbing roses have a long blooming period, and pruning before flowering can promote blooming and extend the flowering period. During pruning, the top buds are first cut off, followed by thinning of densely grown branches to avoid unnecessary nutrient loss and to provide adequate nutrition for the plant's later flowering.
4. Pruning After Flowering
After the flowering of climbing roses, pruning is also required. Remove withered flowers and枯枝, and thin out long and dense branches to facilitate ventilation and light penetration, which is beneficial for the plant's subsequent flowering and growth. Be careful not to prune too heavily, focusing on light pruning to avoid damaging the plant.
5. Winter Pruning
Winter pruning of climbing roses yields better results than spring pruning and is more conducive to a burst of flowers the following year. In winter, when the roses enter dormancy, pruning causes less injury and allows nutrients to concentrate on the leaf buds, which is beneficial for producing strong leaf buds and abundant flowers.
(1) Winter Pruning Principles
Winter pruning should not be too severe. It's important to keep strong main branches and robust secondary and tertiary branches. New thick branches emerging from the roots should be retained as they will produce future flower buds. Strong branches should not be cut off, nor should they be shortened or topped.
(2) Winter Pruning Locations
Firstly, diseased and pest-infested branches should be removed to prevent the spread of diseases and pests. Secondly, old branches should be cut, as branches that have been growing for 4 to 5 years tend to age, reducing their flowering ability and the ability to produce new branches, which is useless and only wastes nutrients. Aging branches are characterized by gray or gray-brown bark on the lower and middle parts. Fine and weak branches emerging from the roots can also be pruned to reduce nutrient consumption and improve ventilation and light penetration, lowering the probability of disease and pest occurrence. Branches that affect growth and shape, such as crossing and dense branches, should be pruned to avoid hindering ventilation and light. Side branches growing from the leaf axils should also be pruned, shortening strong and overlong branches and retaining three plump buds, while removing weak lateral branches.
