Red branches freeze and wither
Today, I will introduce the knowledge about red branches freezing and withering, as well as what to do when the new buds of roses freeze and wither. Next, the editor will answer your questions in detail.
After a night of north wind, many friends find that their roses are not in good condition. The originally red new buds are a bit wilted, some leaves have turned yellow, and some leaves have burned edges. What should we do now? How to save them?
No need to worry, our roses are very tough and cold-resistant. They are just not adapted to the sudden low temperature. Now I will teach you how to deal with different seedling conditions.
1. Red branches freeze and wither
If the roses are in the germination period and are all red tender branches, they may droop after encountering a cold current. At the same time, the new leaves at the top may also have some burnt edges, which are all manifestations of frost damage.
Roses have good cold resistance and can tolerate low temperatures of -20 degrees, but the cold resistance of new branches is relatively poor, especially when the temperature plummets. Tender branches are easily frozen or damaged.
If the branches do not show signs of dehydration and withering, you can first move the potted plants to a warm and sunny place. Don't rush to cut them. Let the roses recover slowly. Generally speaking, after the weather clears up and the sun shines, most of them can recover. After all, the first降温 in winter can only be considered a small test.
Even if some tender branches freeze to death, you can leave them alone and let them go into natural hibernation. For potted roses in the stage of new branch growth, if they are not moved indoors in winter, they will naturally hibernate and will not wait to bloom. I personally suggest that there is no need to spend too much energy and it's best to let nature take its course.
2. Flowers droop
If our roses have grown many flower buds and some of them are in a half-open or colored state, they may have drooping flower buds or be covered by snow after this low temperature.
In this case, it's okay. Relatively speaking, the branches that have developed flower buds are more mature and more cold-resistant. It is recommended to remove the snow and move them to a warm south-facing balcony to recover the seedlings.
Then keep them on the south-facing balcony or corridor, away from frost, and ensure they receive sufficient sunlight during the day. The flower buds still have a chance to bloom. After all, this cold air mass does not last long and is already in the process of warming up.
It is important to note that you should not rush to cut. You must put away the scissors and control your hands for the time being.
3. A large number of yellow leaves appear
Some large rose seedlings or rose vines in windy areas may have a large number of yellow leaves after this cooling. It's okay, just pick off the yellow leaves or let them fall off naturally.
Do not break the newly sprouted buds of the climbing roses, including the newly grown shoots, at the beginning of autumn and winter. The most important thing is to let nature take its course and not to break the shoots at will.
For roses, they know better than us when it's a good time to grow shoots. If they can grow, it means that the overall environment is suitable for them. In fact, after the temperature returns to normal, there may still be about a month of growing period. During this time, the shoots of the climbing roses can grow more than one meter. Even if the weather continues to be cold, the shoots will not grow this year and will continue to grow in the spring. So don't worry unnecessarily and don't be too eager to act! Haha, that's all for today.
Have you understood the detailed introduction of red branches freezing and withering, flowers drooping, and a large number of yellow leaves that I introduced above?
