How to Deal with the Leaf Drop Problem of Roses
After spring, it is common to encounter the problem of rose leaves dropping for no apparent reason. Within a few days, the leaves drop, leaving only the bare branches, which look unattractive. How to solve this leaf drop issue.
There are many reasons for the massive leaf drop and yellowing of rose leaves, such as excessive watering, too much rain, over-fertilization, and a common disease from spring to autumn, which is the leaf mite, also known as the red spider. These leaves will gradually turn yellow, white, or gray, all turning yellow within a few days.
When examining both sides of the leaves, you will find a pile of white or yellow bugs, as you can see, gathered around the veins. This is the red spider, or what we commonly call the leaf mite.
These bugs will suck the sap, causing the leaves to be malnourished and not grow well. Within a few days, they will turn yellow or drop. This is very common in rose cultivation. Therefore, many rose experts always keep a pesticide at home to eliminate red spiders.
For example, Rose Guard, which contains a red bottle called螺螨酯 (spirodiclofen), specifically designed to kill dozens of types of leaf mites, including red and white spiders. After infection, just dilute it with water 300 to 500 times and spray it every three to four days, making sure to spray both sides of the leaves.
Because many leaf mites like to hide on the back of the leaves to reduce the area exposed to light, it's important to spray the reverse side of the leaves, covering every corner. Spirodiclofen can kill all these red spiders and leaf mites, and you can see the effect after about two sprays.
