How to deal with the yellowing and drying of the branches of Chinese roses?
Yesterday, I saw many videos of strong winds shared by flower enthusiasts in my circle of friends, which reminded me of the experience of a student who participated in the "Bestselling Flower Wall Creation Camp" a few days ago.
Although his climbing roses were not very vigorous, they were considered quite healthy. However, because a net was placed under the plants during planting, it hindered the growth of the roots of the roses, causing these plants to grow poorly. Therefore, last month, when the temperature was relatively low, he removed the net, which is equivalent to transplanting the plants, and as expected, it caused some damage to the roots.
For two weeks after removing the net, the plants were in a relatively normal state, but suddenly, a large number of yellow leaves appeared in the past two days. These yellow leaves seemed to appear overnight, accompanied by the yellowing of the branches.
Why is this so?
Many flower enthusiasts may think this is because the roots were damaged by removing the net. Although this is not the direct cause of the yellow leaves, it does have some influence.
The most direct reason is still the strong wind. The location of these two roses is relatively a windy area, and it was indeed very windy the day before the yellow leaves occurred. Although rose flowers are cold-resistant, they are easily damaged by cold winds.
Severe cold winds can easily dry out the branches, and combined with the root damage two weeks ago, the ability of the rose plants to resist harsh external environments is greatly reduced, resulting in such a large area of yellow leaves overnight.
How to deal with the yellowing and drying of the branches of Chinese roses?
In the past few days, there has been a widespread drop in temperatures nationwide, and many areas are experiencing strong winds. With the experience of a student from the Green Plant Enthusiast Network Flower Wall Creation Camp, I would like to remind all rose growers to pay attention to preventing cold winds in winter.
For roses planted in windy areas, it is best to take shelter measures during strong wind weather. Shrubs can be covered with buckets or cardboard boxes, and climbing roses can be covered with plastic film or three-proof cloth to prevent the branches from drying out.
Another point that needs attention is that if roses suddenly have a large number of yellow leaves or the branches dry out and lose water, in addition to considering weather factors, it is also necessary to consider whether the rose roots are damaged.
Generally, roses can withstand cold winds without such a strong impact unless they are in a windy position during strong wind weather. Otherwise, we need to consider another situation, which is whether there is soil pest damage.
Underground pests such as the larvae of the golden turtle beetle or the larvae of the longicorn beetle can cause significant damage to roses, but the symptoms develop slowly and are difficult to detect if not observed carefully.
Often, after prolonged rain or strong winds, there is a sudden appearance of a large number of yellow leaves and the epidermis of the branches becomes wrinkled and lacks water. For the prevention methods and early symptoms of underground pests, you can refer to the book "How to Grow Explosive Roses from Scratch."
