How to prune the suckers of climbing roses?
In the past few days, the new shoots of the roses have been popping out. In the love circle, many flower friends have asked about the related issues of pruning rose suckers. So today, let's make a detailed explanation, hoping it will be helpful to you.
What is pruning suckers?
Many novice flower friends may not fully understand the meaning of pruning suckers and when to do it. Pruning suckers is a kind of pruning, which involves pinching off the new shoots of the plant. Interested flower friends can refer to the book "Cultivating My Potted Plants from Scratch" for very systematic and comprehensive content.
Do climbing roses need to be pruned for suckers?
Roses often need to be pruned for suckers in early spring to ensure that each new branch can bloom and maintain a relatively perfect shape. Therefore, many flower friends ask: Do climbing roses also need to be pruned for suckers?
In fact, we do not prune the suckers of climbing roses, or we don't have the energy to do it! Climbing roses often grow very tall, and it is necessary to use a ladder to prune and牵引 them in winter. Pruning for suckers in spring would be too much work.
Moreover, a major characteristic of climbing roses is "blooming on weak branches," so there's no need to worry about too many suckers on climbing roses. They rely on the numerous emerging suckers to achieve the effect of blooming in abundance and covering the wall with flowers. Generally speaking, if the winter pruning is done properly, the retained branches are strong, and there are almost no blind suckers in spring. Only some suckers in the interior or bottom may become blind due to lack of sunlight.
Of course, if the winter pruning is not done properly and many thin branches are retained, some blind branches will also appear in spring. However, these blind branches are negligible compared to the number of flowers on climbing roses. In spring, we just need to pay attention to supplementing fertilizer and water and preventing diseases and pests, and then we can sit back and enjoy the flowers.
Pruning Principles for Shrub Roses
For shrub roses, most are potted, and a large number of new suckers tend to sprout in spring, which can easily lead to insufficient nutrients. Generally, we will choose to prune the suckers during the germination period, removing some weak and dense suckers to concentrate nutrients (G-Y) and ensure that each new branch can bloom, with large and standard flowers.
The general principle of pruning is "remove the weak, keep the strong, remove the dense, keep the sparse, remove the inner, keep the outer." For shrub roses with a more sprawling shape, "remove the outer, keep the inner" to make the new branches converge inward, avoiding too much sprawl and taking up space.
When pruning, special attention should be paid to the nodal points, where many new suckers often emerge simultaneously. We need to remove the weak small suckers.
At the same time, for twin suckers, one should be removed, leaving only one. Twin suckers are like twins; if both are kept, the growth of the branches will inevitably be affected, and the quality of the flowers will not be guaranteed.
For shrub roses, how much to prune and how much to keep depends on the strength of the plant. If the plant is strong, you can keep more suckers. If the plant is weak, fewer suckers should be kept to strengthen the rose plant.
You can also refer to the book "How to Cultivate Roses from Scratch" for comprehensive and systematic methods to strengthen roses.
For mini roses, we generally keep more suckers, removing only the inner suckers and those that are too dense and twin suckers. For cut roses, we often calculate the number of suckers, keeping only 6-8 strong ones, as this results in high-quality flowers that are very beautiful for flower arrangements. If too many suckers are left, the flowers may become small due to insufficient nutrients (G-Y).
For ground-planted roses, since they have more growth space and access to more nutrients, they can also be pruned without suckers. Even if there are some blind branches, they can be cut off when pruning after flowering, usually with little impact.
