Today's experience sharing: method of pruning roses in winter and whether it is possible to prune roses when it snows, as well as the content about green plants and flowers. It's a great piece of knowledge, recommended for collection!
This cold wave has brought snow to many areas. While enjoying the snow scenery, it also reminds people if it's time to prune the roses? In most regions, we prune roses around mid to late January, which is the coldest time of the year.
This year, the New Year comes earlier, with Chinese New Year's Eve on January 31st. According to the weather forecast, the next month will be colder around January 12th. If you don't have many roses, it is recommended to wait a bit longer and prune around January 10th. But if you have many roses, you can start pruning and repotting some now.
Method of Pruning Roses in Winter
How exactly should we prune roses in winter? Many flower friends are afraid to start. In fact, in areas with frost, the requirements for pruning roses in winter are not high. The most important point is to "cut generously".
Pruning roses in winter is to maintain a better plant shape and flowering quality for the coming year. Flower friends who have kept roses know that after a year of growth, roses tend to grow tall in winter, flowering becomes less, the flowers become smaller, and the heights are uneven. By pruning roses in winter, we aim to bring the roses back to a new starting point, so we must cut generously.
1. -- Overall Pruning --
If it's a potted rose, generally prune 1/2 to 2/3 of the total height of the rose plant. This is for most potted roses because they usually do not grow very tall, and pruning within this range can maintain a good shape.

However, if it's a rose planted in the ground or a very tall variety in a pot, during winter pruning, it is recommended to keep only 15-20 cm above the ground and cut off the rest. Many large shrub roses can grow up to 2 meters tall in one year. If not pruned drastically, they will keep growing taller, and the quality of flowering will decrease.
2. -- Detailed Adjustments --
After overall pruning, we still need to make detailed adjustments. For varieties with a more upright shape, it is necessary to keep outward-facing buds. For varieties with a more sprawling shape, some inward-facing buds can be retained to prevent the plant from becoming too sprawling.
For some weak branches, they should be cut off completely. Dense branches should be thinned, and very old branches with low vitality should also be cut off, keeping only a few thick branches as main branches.
After pruning, the rose should be in a very "clear" state, and the retained buds should be at a relatively uniform height.
The aforementioned winter pruning method is only suitable for shrub roses. Please do not prune climbing roses like this. For the pruning and training methods of climbing roses, you can refer to the detailed introduction in the book "How to Grow a Burst of Roses from Scratch".
