Such rose branches cannot be retained.
This article provides a detailed explanation of why such rose branches should not be kept, covering knowledge about green plants and flowers. Let's follow the editor to take a look!

Excerpt from the "Three-Step Method for Growing Roses" series.
Then, some flower friends left a message asking: *How to prune roses correctly?*
We say that the pruning of roses accompanies the entire growing season of roses, and a major cut is still needed during the winter dormancy period.
In previous articles, we have discussed different pruning methods during the growing period of roses. Today, let's talk about how to prune roses in winter!
The purpose of sharing is to ensure that all flower friends not only know what to do but also truly know how to do it.
To do a good job of pruning roses in winter, we first need to understand:
Why do we need to prune in winter?
Why do we need to prune in winter? Let's analyze from the following three aspects:
1. Plant Shape
Roses bloom on new branches. If heavy pruning is not done in winter, new buds will sprout at the top of the old branches in spring, causing the plant to be very tall. From the perspective of controlling plant shape, pruning is also necessary in winter.
2. Improving Nutritional Relationships
If not pruned, the branches of roses will be very long, and the distance for nutrient transport will be relatively far, resulting in more nutrient loss at the top of the branches, which can lead to weak growth of new buds or even blind buds that do not bloom.
3. Plant Renewal
New branches of roses have stronger sprouting power. If there are no healthy new branches, it will be difficult for the rose plant to renew, and over time, there will be issues of plant aging.
Considering the above three points, we need to do a large-scale pruning of roses in winter to reduce the height of the plant and make it sprout stronger new branches in spring and produce higher-quality flowers.
When to do the winter pruning?
The best time for winter pruning of roses should be after roses enter the dormancy period.
After roses enter a dormant state, their nutrients will flow back to the roots, reducing transportation to the top of the branches, and growth will stop.
How to determine if roses have entered the dormancy period?
In frost regions, roses will enter the dormancy period after defoliating in winter. Many roses in Jiangsu and Zhejiang will not defoliate but will stop growing, and the stems and leaves of roses will turn red, which are all signs that roses have entered the dormancy period.
It should be noted that in warm southern regions, roses do not enter dormancy and should not be pruned heavily.
How to prune?
Winter pruning of roses should first remove dead branches, diseased branches, and weak branches.
Weak branches cannot meet the conditions for flowering, and if retained, the buds that sprout in spring will also be blind branches that cannot bloom, as mentioned in yesterday's article.
So, what qualifies as a weak branch that cannot bloom?
Different flower shapes have different requirements for branches. Here is a reference standard for you:
For large-flowered roses with stems over 10cm, only branches as thick as pencils should be retained, and thinner branches should be cut. For medium-flowered varieties with stems between 6-10 cm, branches as thick as one-time chopsticks should be retained, and thinner branches should be cut. For small-flowered varieties, branches as thick as toothpicks should be retained, and thinner branches should be cut.
This pruning reference standard is not only applicable to shrub roses but also to climbing roses. You can remember it and use it as a reference when pruning.
Such rose branches cannot be retained.
When pruning in winter, in addition to cutting off dead branches, diseased branches, and weak branches, we also need to observe the condition of the branches, look for healthy and full buds, and prune above them.
Generally, the pruning height is 1/2 or 1/3 of the plant.
When pruning, it is important to try to keep all the retained buds at the same height so that they will sprout uniformly in spring.
Of course, a higher level of pruning should be based on the condition of the branches, with stronger branches kept shorter and relatively weaker branches kept longer. This will result in a more balanced growth of new buds.
Attention should be paid to the following:
If it is a potted shrub rose, do not retain too many buds. Calculate the number of buds that will sprout in the future to meet the plant shape requirements. Retaining too many buds in spring can easily lead to insufficient nutrition.
Also, when pruning, attention should be paid to the direction of the retained buds, trying to distribute them evenly. If the buds are预留ed incorrectly, it can easily cause the plant shape to be crooked.
For example, too many inner buds can cause the plant to be too crowded in spring, and too many single-side buds can make the rose plant lean to one side.
The above is an introduction to the winter pruning method for shrub roses. When pruning climbing roses in winter, just cut off the dead branches, diseased branches, and weak branches, and trim the top of the branches. There is no need to cut back a large number of branches.
The most important task for climbing roses in winter is traction, which will be shared by Green Plant Enthusiast Network later. Welcome to follow my public account: Green Plant Enthusiast Garden (ilanyao)
