I. How to grow mosquito repellent plant in water

1. Choose strong, robust branches and prune them. Choose a diagonal cut, as this can increase the area of the cut surface exposed to water. Then cut off the lower leaves, keeping a few leaves at the top.

2. Drill a small hole in foam that is about the same thickness as the plant, then insert the mosquito repellent plant branch into it. Pour a certain amount of water into the water culture container, then place the mosquito repellent plant branch into the container for water culture. The foam board can not only fix the plant, but also reduce water evaporation. In addition, note that the length of the mosquito repellent plant branch submerged in water should not be too long. It is recommended to disinfect the water culture bottle before use.

3. Change the water every four or five days. When changing the water, pay attention to cleaning and disinfecting the water culture container. In addition, to ensure the health of the water-cultured branch, also promptly clean off any rotten or secreted substances and leaf and branch tissue on the branch. You can occasionally spray a little water on the leaves of the branch. It is recommended to use purified water for the water culture, or you can add a small amount of nutrient solution to it.

4. With proper daily care, generally after about 15-30 days, you can see the mosquito repellent plant take root. Once you see that the roots are growing healthily, you can transplant it in time. In the first week after potting, it is not recommended to place it in sunlight. Wait until the plant grows new leaves; at this point you can confirm that the mosquito repellent plant is growing very healthily, and then you can place it outdoors to receive sunlight.

II. What types of mosquito repellent plant are there

1. Mosquito repellent plant

The mosquito repellent plant has a lemon fragrance. Kept indoors, mosquitoes will quietly flee as if avoiding a plague... Especially in hot summer, it can make people feel refreshed and relaxed. Authoritative testing shows that its mosquito repellent effect is good and it is harmless to humans and livestock. The mosquito repellent plant is a perennial herbaceous plant; it can be cultivated indoors and outdoors. Generally, the higher the temperature, the stronger the fragrance and the better the mosquito repellent effect.

2. Insectivorous plant

A herbaceous plant of the Asteraceae family, it can grow to about one meter tall, with small yellow flowers, and a single plant can have hundreds of flower heads. The outer bracts of each flower head have mucus, just like 5 extended little fingers, which is very interesting. As long as a small mosquito lands on it, it will be stuck. After that, the insect carcass is slowly digested by it and used as nutrients for its growth. If dust sticks to it, after a few days it is also digested without a trace. Placed as a potted plant at home, it catches mosquitoes and absorbs dust.

3. Lantana camara

Its branches, leaves and flowers emit a scent that mosquitoes and flies are sensitive to, with a strong effect of repelling mosquitoes and flies, while causing no harm to the human body. It not only has a good effect in repelling mosquitoes and flies, but also has bright flower colors. The flowers are red, yellow, white and other colors. When the flowers first open, they are often yellow or pink, then gradually turn orange-yellow or orange-red, and finally red, which is why it has the reputation of "seven-change mosquito repellent flower." Placed by the window, it is pleasing to the eye.

4. Night-blooming jasmine

Mosquitoes are afraid of the strong scent of night-blooming jasmine, so placing fragrant flowers indoors can naturally achieve a mosquito repellent effect. Most of these flowers are elegant and pretty, easy to grow, and not expensive. In addition, when they bloom in summer, the green and white contrast makes people easily feel a sense of coolness. However, according to reminders from relevant experts, the fragrance of flowers such as night-blooming jasmine often feels refreshing at first, but after smelling it for a long time, because it is too strong, it may cause discomfort. It is recommended to move the potted flowers outdoors during the day....

III. How to prevent and control pests and diseases in mosquito repellent plant

1. Disease control

(1) Leaf drop symptoms

First, due to management problems, improper management will cause the plant roots to rot and the leaves to become wrinkled and shrunken. This situation is caused by high air humidity and poor ventilation. At this time, it is necessary to spray some fungicide and control the amount of fungicide properly. If leaf drop and yellowing occur in a short period, this may be caused by temperature imbalance and insufficient light, so provide sufficient light on time.

(2) Poor development

When planting, if alkaline soil is used for cultivation, it will cause the plant to be short and stop growing. Sometimes it is also caused by using water containing alkali for irrigation. In this situation, you can loosen the soil on time, remove the top layer of soil, add some new soil again, and then add a small amount of diluted agent to improve the soil properties.

(3) Viral disease

A virus is a substance we cannot see with the naked eye. It can parasitize in the living cells and tissues of plants, and then transfer to various parts of the plant together with organic matter. When this happens, we need to remove the diseased plant in time, and when planting, choose plants in good health for cultivation.

2. Pest control

White grubs are generally called scarab beetles and appear as white fleshy bodies. They can feed on the roots of plants and gradually damage the plants. The method to control this pest is to remove the insects you see when repotting, and then use insecticide to sterilize the roots.
