What to do if there are insects on the leaves of gardenia

1. Aphids

1. Introduction: It is the most important insect pest, which is harmful to roots, stems and other parts.

2. Treatment: The treatment method should be adjusted according to different periods. If it is in the early stage, you can rinse the plant directly with clean water. If they are not rinsed clean, wipe them clean with a cloth. Be sure to remove them completely, otherwise they will multiply quickly. If the disease is very serious and the number of insects is very large, you will need to use medicine, such as dichlorvos. Or you can use smoke or mosquito coils.

2. Scale Insects

1. Introduction: They not only directly harm the plants, but also indirectly cause soot disease, so they must be dealt with in a timely manner.

2. Treatment: In the early stage, you can use Dan powder to kill insects. If the situation is more serious, you can eliminate them by spreading lime powder. After killing most of the insects, place the plant in a shaded, windy place. Also pay attention to drainage, which can promote plant recovery and prevent pests.

3. Red spider

1. Introduction: It will cause the leaves to turn yellow and the plants to grow poorly, usually appearing on the back of the leaves.

2. Treatment: Prevention is very important. The temperature should not be too high and the light should not be too strong, otherwise red spider mites will easily breed. After discovering them, if the number is small, you can flush them away with clean water, or use water soaked with cigarette butts. When the quantity is large, pesticides can be used, such as omethoate.
