How to prune shrub roses to form a trunk
Main content core guide: Knowledge about the pruning techniques of shrub roses to form a trunk and the pruning techniques of single-stemmed rose trees in the field of green plants and flowers, with detailed introduction below.
Pruning roses in winter is a very important task in the annual maintenance of roses.
It affects the quantity and quality of roses the following year.
Moreover, rose pruning is time-limited.
It is usually done when the leaves turn yellow and the branches and leaves mostly fall off, like this.
At this time, the branches have also slowly turned into a reddish-brown color, and the color will deepen.
This indicates that the roses can be pruned.
Today, Xiao Zheng will first share the pruning methods for shrub roses with everyone.
When pruning shrub roses, I generally divide them into two situations: potted and planted in the ground.
Let's first talk about the pruning method for potted shrub roses.
Nowadays, it is usually the balcony party, and there are more friends who grow plants in pots.
Potted roses have a limited supply of nutrients, and if they grow too tall, they may not get enough nutrition.
What we can do is to make them bloom as many flowers as possible with the limited nutrients.
Winter pruning of shrub roses is generally recommended to be severe.
Because shrub roses are strong, the branches they grow are also robust.
So, it is enough to retain 3-5 buds on each main branch.
This can be decided by the distance between the buds.
If the distance between the buds is long, retain 3 buds.
If the spacing between the buds is short, you can keep a few more.
Then find a suitable outward-facing bud, as keeping an inward bud easily grows crossed branches.
Make a cut 0.5-1 cm above the full outward-facing bud, making sure to cut at a 45-degree angle.
This completes the pruning of one main branch.

Then prune the other main branches as well.
Branches like these crossed ones should also be pruned, as they not only produce a few flowers but also affect the ventilation of the plant.
After pruning, check again for any withered or diseased branches, which also need to be pruned.
This way, after pruning, these buds near the roots can absorb enough nutrients and gain tremendous energy, resulting in strong branches.
Moreover, many suckers may emerge next spring.
This will lead to more flower buds and better quality blooms.
This is the pruning method for potted roses, and there is also the pruning method for shrub roses planted in the ground.
Roses planted in the ground have more developed root systems and grow quickly, allowing better absorption of nutrients.
I usually perform light or medium pruning.
Prune 3-4 buds from top to bottom, and then prune the withered, diseased, weak, crossed branches, etc., in the same way.
After pruning, whether potted or planted in the ground, clean up the surface withered leaves, as these leaves can lead to diseases and pests, especially for potted plants.
After cleaning, there is one more thing to do, which is fertilizing.
Fertilizing roses in winter is simple; you can bury some organic fertilizer on the surface of the potting soil.
This way, the nutrients can be supplied adequately, and the first wave of growth in the spring of the following year will be more vigorous.
After everything is done, place them directly outside for maintenance.
Roses can survive the winter outside in the Jiangsu, Zhejiang, and Shanghai areas, and after winter dormancy, their growth will be even more vigorous next year.
Today's introduction to the winter pruning and maintenance of shrub roses is over.
The detailed introduction shared above about how to prune shrub roses to form a trunk and the pruning techniques of single-stemmed rose trees, I hope everyone will like it!
