How to solve the problem of yellowing and falling leaves on roses
As winter approached, some flower enthusiasts asked me what to do about the yellowing and falling leaves on their roses.
1. Low temperature
First of all, it's quite normal for roses to have yellowing and falling leaves, not withering branch disease. So, if it's not withering branch disease, what causes the yellowing leaves?
It's simple. In winter, due to low temperatures, the roots do not grow and cannot absorb nutrients and water, causing the upper leaves to turn yellow and gradually fall. However, at this time, you should remove some yellow leaves.
2. Preventing diseases
After removing the yellow leaves, remember to prevent diseases. Why prevent diseases? If you're not careful, they can be infected with bacteria and easily develop withering branch disease, etc.
So at this time, like me, I usually choose to use Mancozeb, which can prevent diseases and also kill some harmful bacteria. Of course, if you don't have Mancozeb, you can also choose to use carbendazim solution. After preparing it, mix it well and then spray it on the plant and soil. This way, withering branch disease won't appear later on.
