Sharing knowledge on overwintering rose pruning times and methods, as well as winter pruning techniques for old rose stakes, the editor will provide you with detailed answers below.
From ancient times to the present, roses have been widely cultivated in China and are deeply loved by everyone. To grow roses well, attention should be paid to pruning at the right time after entering winter. In the south, it is suitable to prune from the end of January to the beginning of February, while in the north, it is from the end of February to the beginning of March. There are many varieties of roses, and they are widely used. Some are large-flowered fragrant roses for cutting, and others are climber roses for ornamental and beautification purposes. Here we will specifically discuss when to prune roses after entering winter and the pruning methods.
1. Pruning Time After Entering Winter
1. Principles
Winter pruning should not be too early or too late. It is best to prune heavily once after the roses enter the dormant period. If pruning is done too early, and the plant has not yet entered the dormant state, the buds on the branches may continue to grow, causing the new branches and leaves to be frostbitten.
If pruning is delayed, nutrients have already been supplied to the top of the plant, and pruning at this time will unnecessarily consume the plant's nutrients.
2. Southern Regions
It is usually suitable to prune in the south around the Spring Festival, specifically during the lowest winter temperatures, from the end of January to the beginning of February.
3. Northern Regions
Due to the large climatic differences between different regions of our country, pruning times also vary. In the north, pruning can be done from the end of February to the beginning of March.
The reason is that the climate in the north is severe, and rain and snow falling on the pruned wounds can easily cause diseases and pests, so pruning should wait until the temperature slightly warms up.
2. Pruning Methods After Entering Winter
1. Shrub Rose Varieties
When pruning roses in winter, some branches need to be cut, and the pruning method depends on the variety of the rose. For shrub rose varieties, branches should be shortened, requiring a 45-degree angle cut, generally pruning to retain 3 to 6 branches about 25 to 35 centimeters long.
2. Climber Rose Varieties
For climber rose varieties, it is necessary to thin the branches, pruning off the diseased, weak, and old branches, mainly to allow nutrients to flow back to the main stem.
3. Old and Young Plants
For old plants, the top of the main stem should be pruned to 15 centimeters high. It is not suitable to prune single branches.
3. Pruning After Flowering
Roses bloom from August to the following April. A light pruning should be done after the flowers fade each month, cutting the branches to 30 centimeters and removing long thin branches. Winter post-flowering pruning should be done at the end of December.
