Common Examples of Winter Pruning for Large Climbing Roses
Today's topic brings you the small experience of pruning old climber roses in winter, specifically introducing as follows:
It's time for the annual pruning of climber roses. Pruning small climber roses is relatively simple. I have introduced this in previous articles. Friends who missed it can review past articles. Today, I will introduce the pruning method for large climber roses, hoping it will be helpful to you.
Common Examples of Winter Pruning for Large Climbing Roses
Climbing roses grow very quickly, especially some large varieties, which can grow quite large after just two years. Whether it's a climber rose that has been planted for 2 years or 5 years, the general principle for winter pruning is the same: keep the strong and remove the weak. There are several common types of branches.
1. - - On last year's牵引 branches, new branches are weak. - -
For example, the branches marked ① and ② in the picture above. Of course, our rose branches are more numerous and complex than the ones drawn in the picture, but that doesn't matter. We simplify and grasp the essence.
The branches marked ① and ② represent the branches that were牵引ed last winter. After flowering in the spring, these branches basically stop growing, so the new branches that grow on them are very short and thin, indicating that these old branches are not very vigorous.
If our rose plant has strong new branches like ③ and ④, then the old branches like ① and ② can be cut off completely.
2. - - Last year's old branches with strong new branches - -
As shown in the picture above, strong new branches like ③ and ④ have grown on the old branches ① and ②, which are long and sturdy. When strong new branches appear on old branches, it indicates that the branches are still vigorous, so when pruning, just cut off the weak parts and keep the strong new branches for牵引.
For climber roses that have been planted for many years, it's easy for strong new branches to grow on old branches with sufficient fertilizer and water. Some may even grow near the top of the branches, so pruning must be done carefully to avoid误剪.
3. - - Pruning with and without branches at the top of new shoots - -
Healthy climber roses will definitely have many strong new shoots. Generally, the shoots that grow in spring and summer will have many small branches at the top by the time of winter pruning. It is recommended to keep the longer branches as appropriate. As shown in the picture below.

The branches ④ and ⑤ are the new shoots that grew in spring and summer, with many branches at the top, but the growth of the branches varies. The branches of ④ are stronger, and it is recommended to keep 1-3 long branches. The exact number depends on the number of branches. If there are enough branches for牵引, you can cut off more, leaving only one long branch, or cut them all off. If there are not enough branches, you can keep one or two more.
Branch ⑤ also has many branches, but they are all thin and short, so it is not worth keeping. It is recommended to prune from the branches.
Branch ③ is a new shoot that grew in autumn and winter and has not had time to bloom. Such branches are very tender, especially the top part, which is prone to drying out in cold weather. It is recommended to cut back about 20 cm from the top.
The examples mentioned above are all healthy climber roses. There is another situation where the roses are not well cared for, with few new shoots and no strong new branches on last year's old branches. Pruning such climber roses is even simpler.
4. - - Weak-growing climber roses - -
As shown in the picture above, the new branches on the old branches are weak, and there are very few sturdy branches overall. In this case, we can follow last year's牵引 shape and just cut the thin branches short.
Weak branches can be kept with 2 buds, and the rest can be cut off. If the branches are relatively strong, you can keep more buds according to the robustness of the branches. After pruning, the remaining new branches can be牵引ed moderately.
