During this period leading up to the New Year, it is a good time to prune and repot roses. Many flower friends have already started, but in the past few days, several flower friends have left messages asking whether it is okay not to prune roses in winter? What are the consequences? Do roses really need to be pruned in winter? Do you also have such doubts?
One, why do roses need to be pruned in winter?
First of all, let's understand why roses need to be pruned in winter? What is the purpose of pruning?
Friends who have raised roses know that roses are a plant that blooms on new branches, which means that only when the rose seedlings grow new branches, they will bloom at the top of the branches. If the rose does not sprout new buds and has no new branches, it cannot bloom.
Plants have apical dominance. When the flowers on a branch fade, if not pruned, new branches will grow at the top of the branch and continue to bloom. Therefore, after a year of growth, roses often have relatively tall plant shapes.
For potted roses, it is still okay, generally not very tall, but for shrub roses planted in the ground, they can often grow to a height of more than 1.5 meters in a year. So, one of the most important purposes of pruning roses in winter is to dwarf the plant shape of roses, not allowing them to grow too tall. Especially for potted roses, growing too tall takes up space and does not look good.
In addition to dwarfing the rose plant, strengthening the rose is also a very important pruning purpose. Generally speaking, the new branches closer to the root will grow more vigorously and have thicker branches. Therefore, winter pruning can remove weak branches and retain strong branches and full buds, so that new branches will grow strong in spring, and the flowers will also be larger and more beautiful.
Two, do all roses need to be pruned in winter?
Then, do all roses need to be pruned in winter? Many flower friends say, my roses have not entered dormancy yet, how can I prune them?
Actually, whether to prune roses in winter depends on the region. In areas with frost in winter, such as regions north of Jiangsu, Zhejiang, and Shanghai, it is relatively cold in winter, and roses will enter dormancy. After dormancy, they will be pruned in winter. In areas like Guangdong, Guangxi, and Fujian, the lowest temperature in winter is always above 5 degrees Celsius, roses do not go into dormancy, and they continue to grow and bloom in winter, so they do not need to be pruned, nor can they be pruned heavily.
In addition, our climbing roses do not need to be pruned heavily. Climbing roses should only prune old, vitality-less branches and weak branches that cannot bloom. For the specific pruning method of climbing roses, you can refer to the previous sharing or read the book "How to Raise a Bursting Rose from Scratch," which also has detailed instructions.
Three, what will happen if roses are not pruned in winter?
What will happen if roses are not pruned in winter? Flower friends in the south should have more experience with this, as roses do not go into dormancy in the south and there is no opportunity to prune heavily in winter. If the branches are not pruned after flowering, they will undoubtedly quickly grow into a small tree.
In the southern regions, in order to maintain the shape of roses, it is usually necessary to prune the branches promptly after flowering. When the growth of the rose plant weakens, it is also necessary to press the branches to promote suckers, using suckers to update the plant and maintain the vitality of the rose plant.
What will happen if roses in the dormant area are not pruned in winter?
Because of the cold winter, roses are in a dormant state, and many bud points have accumulated a lot of nutrients. When it warms up in the spring, these bud points will sprout in large numbers. Therefore, with sufficient fertilizer and water, you can harvest many flowers, tall plant shapes, and a large number of blind buds in the spring.
Because it has not been pruned, the height will definitely be higher than the previous year, and many new buds will become blind branches due to insufficient light and fertilizer. There will also be some withered branches inside, but the flowers can still bloom continuously, just the new branches will become thinner and the flowers smaller.
The above is [] about why roses need to be pruned in winter, whether all roses need to be pruned in winter, and what will happen if roses are not pruned in winter. I hope it brings a little help to your life!
