Is mosquito repellent plant useful? Teach you the correct cultivation method
Summer is here, and all kinds of mosquitoes and insects have begun to become active, making people endlessly annoyed. But mosquito coils, insect repellent sprays, and other chemical products all have slight toxicity, and physical methods like electric mosquito swatters are tiring. To eliminate mosquitoes and insects in a long-lasting and healthy way, we started to set our sights on plants - mosquito repellent plant. But is mosquito repellent plant really useful? How should mosquito repellent plant be grown?
I believe many people who grow mosquito repellent plant truly have high hopes that they can eliminate mosquitoes and insects, but is mosquito repellent plant really useful? Some say it is useful, some say it is useless, and some say that even if it is useless, it is nice to grow it for appreciation. Today we will talk about that little matter concerning mosquito repellent plant.
What is mosquito repellent plant?
What exactly is this "mosquito repellent plant"? The "mosquito repellent plant" sold on the market has thick, downy leaves, with leaf edges that are curved and deeply lobed, somewhat similar to watermelon leaves. Sometimes, this "mosquito repellent plant" also produces small pink 5-petaled flowers, looking very cute as well. Lean in and smell it, and sure enough, there is a fragrance similar to lemon.
In fact, this "mosquito repellent plant" is a "close relative" of the common flowering plant geranium, named scented geranium (Pelargonium graveolens). The fragrance given off by scented geranium is because it can synthesize various volatile aromatic substances including geraniol, citronellal, and others within its body. Compared with geranium, scented geranium has a less irritating scent, so it can also be used as a raw material for extracting essential oil.
Is mosquito repellent plant useful?
Can scented geranium play a role in repelling mosquitoes and insects? If we consider only the substances it gives off, geraniol, citronellal, and others can indeed have a dispersing effect on mosquitoes and insects. Unfortunately, however, these substances need to be released in large amounts only when the leaves are bitten and eaten by mosquitoes and insects, causing damage to the plant tissues. This is actually a way for the plant to protect itself. Under normal circumstances, the amount of these aromatic substances diffused by the plant into the air is far from enough to repel mosquitoes and insects, let alone protect humans from being bitten.
In addition, if too many scented geraniums are placed indoors for "mosquito repellence", making the emitted scent too strong, it will also make people feel uncomfortable. It seems that relying on "mosquito repellent plant" to repel mosquitoes is not reliable.
How to grow mosquito repellent plant?
Although the hope of relying on it to completely eliminate mosquitoes and insects has been shattered, friends should not be discouraged. Mosquito repellent plant still looks quite pleasing, and it gives off a faint fragrance, which also helps to nourish body and mind. So how should mosquito repellent plant be grown?
I. Cultivation methods for mosquito repellent plant
1. Soil
Mosquito repellent plant prefers neutral to slightly acidic soil. Within 6 months, use a special self-mixed nutrient soil of 6 parts peat soil, 1.5 parts vermiculite, 1.5 parts perlite, and 1 part coal ash, with a pH slightly acidic to neutral. You can also buy a prepared (pH 5.5-7) foliage substrate soil. After six months, mosquito repellent plant has extremely strong adaptability and can use any soil. Two-year-old mosquito repellent plant has a lignified main stem and can be pruned, shaping the plant freely according to personal preference.
2. Temperature
Mosquito repellent plant prefers warmth. 10 to 25°C is the suitable growth temperature. Temperatures below 7°C and above 32°C are unfavorable for growth. The indoor overwintering temperature should not be lower than 12°C. Above 15°C, it can normally give off lemon fragrance, and the higher the temperature, the stronger the fragrance. Spraying an appropriate amount of water mist on the leaves of mosquito repellent plant can make citronellal substances release continuously, thereby making the mosquito repellent effect of mosquito repellent plant better.
3. Light
Mosquito repellent plant prefers shade and cannot tolerate strong light during growth. Especially in summer, shading should be strengthened, and it can be planted under trees or in shady places. Household potted plants are generally placed indoors for shading and cultivation.
4. Watering
After repotting mosquito repellent plant, water it once. Normally, water thoroughly once every 3-6 days, but there must be no water accumulation. Watering should follow the principle of alternating dry and wet. If the surface of the pot soil turns white, water it. In summer high temperatures, water less, and water mosquito repellent plant thoroughly once a week. In July-August, spray water frequently to cool it down and keep the environment around mosquito repellent plant moist.
5. Fertilizing
Start fertilizing 10 days after seedling recovery. Spring and autumn are the vigorous growth periods of mosquito repellent plant, generally fertilizing once every 15-20 days. In early April, after mosquito repellent plant grows new branches, apply a diluted organic liquid fertilizer once a week. In late April, move it outdoors, and mosquito repellent plant will bloom successively. In summer high temperatures, water less and do not fertilize, which is beneficial for the developed root system of mosquito repellent plant and improves disease resistance. For household cultivation, a small amount of cake fertilizer and rice washing water can also be applied.
6. Pests and diseases
Diseases caused by improper management include root rot or stem and leaf rot, followed by leaf shrinkage, black spots appearing, and then the whole plant withering. This is caused by too much humidity, too high temperature, and at the same time poor ventilation or too dense seedlings. Fungicides such as chlorothalonil or carbendazim (800 to 1000 times solution) can be sprayed. But do not spray frequently.
II. Precautions for cultivating mosquito repellent plant
1. Mosquito repellent plant has the best mosquito repellent effect when the plant height is 30 cm and it has 40 leaves. If yellow leaves appear on mosquito repellent plant, they need to be removed promptly.
2. During the day, do not let mosquito repellent plant receive direct sunlight. Too harsh sunlight will make the surface of mosquito repellent plant become scorched yellow. It is best to place mosquito repellent plant on the balcony and just keep the soil moist.
3. After mosquito repellent plant grows up, give it a larger pot. The root system of mosquito repellent plant is quite developed and can absorb many minerals from the soil.
4. If mosquito repellent plant is managed improperly, it will cause root and leaf rot, followed by black spots on the leaves and withering of the whole plant. This is caused by watering too much and lack of ventilation. A little chlorothalonil solution can be sprayed, and mosquito repellent plant should be quickly moved to a ventilated place for cultivation.
5. The common short-term leaf drop is generally caused by insufficient light for mosquito repellent plant, so mosquito repellent plant can be appropriately placed in a place with light for cultivation. Leaf shedding and yellowing of mosquito repellent plant are due to lack of water. In winter, this situation may also be caused by too low temperature. Too much fertilizer or too strong light can also cause scorched yellow leaves, so attention should be paid.
The above is the science popularization introduction about mosquito repellent plant. I hope it is helpful to friends.

If mosquito repellent plant is managed improperly, it will cause root rot and leaf rot, followed by black spots on the leaves and withering of the whole plant. This is caused by watering too much and lack of ventilation. At this time, a little chlorothalonil solution can be sprayed, and they should be quickly moved to a ventilated place.
If mosquito repellent plant suddenly drops leaves, it is because of insufficient light or maladaptation caused by too great a sudden temperature change. There may also be yellowing of leaves and then shedding, which is because the temperature is too low. If mosquito repellent plant has a period of crazy leaf growth, it is because there is not enough light and too much nitrogen fertilizer was applied. They should be promptly moved to a place with good light, and then the branches and leaves should be pruned!
Conclusion: Mosquito repellent plant is a relatively easy plant to grow, but if we are slightly careless, it is also a plant that is very prone to illness.

Orange jessamine: Orange jessamine is an evergreen shrub. The mosquito repellent principle of this mosquito repellent plant is the spicy and sweet fragrance given off by its leaves, which has a very good effect on repelling mosquitoes. Orange jessamine has a corymb-like appearance, with branches very closely spaced, small leaves, and white flowers. It also has ornamental value.
Carnivorous plant: Carnivorous plant is also a relatively well-known type of mosquito repellent plant and is a herbaceous plant of the Asteraceae family. Each plant has more than 100 flower heads, and the periphery of each flower head has mucus, which is its main tool for repelling mosquitoes. When a mosquito lands on it, it will be stuck by the mucus, and then the insect's corpse is slowly digested and turned into nutrients.
Lantana: The mosquito repellent principle of lantana is similar to that of orange jessamine. Its branches, leaves, and flowers all release a gas. Mosquitoes and flies are very sensitive to this gas, so it is very effective for repelling mosquitoes, and it is completely non-toxic to the human body. Lantana also has another name called "mosquito repellent seven-change flower", because its flower colors are very gorgeous and varied. There are various colors such as red, yellow, and white, and as it blooms, the colors will also gradually change, very beautiful.
