The Latest Detailed Guide to Overwintering Climbing Roses
Once winter arrives, many flowers gradually wither under the influence of cold air, especially in the north where it is more obvious, with snowflakes drifting outside and few flowers left on the branches. Although the climbing rose is a relatively cold-hardy plant, it still needs careful attention when faced with this kind of cold weather, so how do you get climbing roses through the winter safely? Today Qinnong Web brings you the methods for overwintering climbing roses.
To get climbing roses through the winter safely, two measures must be taken: the first is pruning, and the second is cold protection. These two points are very important aspects affecting whether climbing roses overwinter safely. Below, Qinnong Web introduces them in detail.
1. Pruning
At lower temperatures, climbing roses generally begin to drop their leaves on their own. We can do a little pruning before they drop their leaves, which will let them get through the winter smoothly. We can cut off all of their flowering branches, diseased branches, thin and weak branches, and so on. In addition, for those old branches that have been there a very long time, they can be cut off as well. In this way, before Frost's Descent they will begin to drop their leaves automatically, and then after they are properly tied up, they will enter a dormant state. Usually larger plants can get through the winter completely smoothly, and if you are really worried, you can also give them a little covering to keep them warm, and there will be no problem at all in getting through the winter smoothly. For small plants, however, getting through the winter is not especially smooth, and they must be cared for more carefully.
2. Cold protection
On the subject of cold protection, Qinnong Web will introduce four points here, including temperature control and the cold-protection measures taken for climbing roses in three different growth states, introduced in detail as follows:
1. Temperature
In winter, temperature is very important for whether it can overwinter safely; regardless of plant size, it can be moved into an ordinary cold cellar, with the temperature controlled at 0 to 5 degrees. Or it can be placed outdoors and buried in soil.
2. For young plants
Some plants that have not yet grown to full size, that is, relatively young plants, have relatively smaller root systems and look weak as plants, so when protecting them from the cold, it must be done more carefully. We can wait until it stops growing, then bury it in soil for cold protection.
3. For larger plants
If your plant is relatively large, then the cold-protection measures should be adjusted accordingly. We can wait until the plant stops growing, prune it a little, and after that, place it in a southeast-facing direction, and also prevent cold wind from reaching it, so as to achieve better insulation.
4. For mature plants
For some plants that have already grown to maturity, if you want them to get through the winter smoothly, generally you pile some soil around their roots and then provide cold protection. Then, after the freezing water has been watered in well, appropriately shorten those long branches, and then pile 20 to 40 cm of soil on them. In this way they can be fully protected from the cold.
The above is the related introduction from Qinnong Web on how climbing roses get through the winter. Have you learned it? Climbing roses enter a dormant state when the temperature drops below 5 degrees C in winter, and some varieties can even withstand low temperatures of -15 degrees C, but even so, they still need some cold-protection and warmth measures in winter, as only this helps them bloom beautifully again in spring.
