What are the characteristics of Chinese roses?
Main text core guide: Let's understand together the characteristics of Chinese roses and related content about the green plant features of Chinese roses.
The weather temperature has obviously dropped, and many people are eager to prune their Chinese roses for winter. However, this is not a rushed matter. If the Chinese roses do not enter dormancy, they should not be pruned in a hurry.
Then, how can we determine whether Chinese roses are in a dormant state?
To determine whether Chinese roses have entered the dormant period, we can distinguish based on the breeding environment and growth status.
Characteristics of Chinese roses in the dormant period:① Environment of Chinese roses
By observing the temperature of the environment where the Chinese roses are grown, we can know whether they have entered the dormant period.
As long as the ambient temperature reaches 5℃ and continues for a period, Chinese roses will enter the dormant period. If the ambient temperature fluctuates, the Chinese roses may not enter the dormant period.
Also, for those small Chinese rose盆栽 on the balcony, it should be noted that climate temperature is only a reference, and the ambient temperature still needs to be considered.
② Stems of Chinese roses
Whether Chinese roses have entered dormancy can be observed by looking at their stems. The stems of Chinese roses entering dormancy will turn red, usually purplish red or brown.
For Chinese roses that have not entered dormancy, the stems remain green, which is easy to distinguish.
③ Buds of Chinese roses
Some Chinese roses will continue to bloom, but once they enter the dormant period, they will stop blooming. The most intuitive way is to look at their buds.
The buds that were gradually changing color and swelling suddenly fail to open, which means that the blooming process is like pressing the pause button. The buds are still there, but they cannot bloom.
This is also one of the characteristics of Chinese roses entering the dormant period.

④ Buds of Chinese roses
The buds of Chinese roses are always abundant, but after entering the dormant period, these buds appear very full and red, but they will not break through and germinate.
Moreover, the previously pruned areas may develop blind buds to varying degrees.
⑤ Leaves of Chinese roses
Most Chinese roses in a low-temperature environment will defoliate, indicating that they have entered the dormant period.
However, some Chinese roses have different manifestations, such as different varieties or different seedling ages, resulting in different leaf conditions.
For example, some Chinese roses may still have leaves after entering dormancy, but more than 30% of the leaves will turn yellow and wither, looking unwell. This can be basically determined as entering the dormant period.
⑥ Roots of Chinese roses
Although the roots of Chinese roses are not easily observable, the above five points are enough to judge whether Chinese roses have entered the dormant period. Nonetheless, let's share the changes in the main roots of Chinese roses during the dormant period.
In the dormant period, the main roots of Chinese roses will become thicker, turning yellow or brown, and the fine roots will gradually dry up and disappear.
If you have to repot during the dormant period of Chinese roses, you can pay attention to this.
