How to prevent and treat the red spider mite infestation on rose leaves
I received a private message from a friend who said that the new buds and leaves of their rose plant had leaves that looked a bit like iron deficiency yellowing, asking me to check if it was truly iron deficient. Many people think this type of yellowing leaf with green veins is due to iron deficiency, but actually, roses are not picky about soil pH, whether it's acidic, neutral, or alkaline, they can all grow. Roses do not have high requirements for the pH value of the soil, so they do not need excessive amounts of iron.
1. Red Spider Mites
At the same time, roses do not show iron deficiency yellowing. Regarding these leaves, let me tell you that this type of leaf may be affected by red spider mites, also known as leaf mites. These pests specifically extract the sap from roses, causing the nutrients inside the new leaves to be absorbed, resulting in sap loss, which leads to the leaves growing like this. Moreover, the flower buds that appear on top cannot open and will gradually fall off. In severe cases, these leaves may also develop wavy-shaped spots.
2. Leaf Mites
After the appearance of leaf mites, it is recommended to use "Rose Guardian." Rose Guardian contains a substance called "spirodiclofen," which is the best pesticide for killing red spider mites and has a quick and effective root treatment. If you notice these leaves or spots, you can also use it.
This spirodiclofen should be sprayed once every three days to improve the environment and prevent the red spider mites from continuing to infect and recur. Generally, after two or three sprays, the new leaves can slowly recover their growth.
This type of damage from red spider mites is most likely to occur in spring, summer, and autumn, especially in the summer and autumn seasons when the air is dry and humidity is low, making it easy to contract red spider mites.
