Reasons for Yellowing Leaves on the Mosquito Plant and How to Fix It
1. Symptom: Sudden yellowing and leaf drop over a short period
Solution: This may be caused by a rapid temperature change or insufficient light. What you need to do is place the mosquito plant in a sunny spot to get more sun, and make sure the light exposure time is increased gradually; it should not be placed in direct sunlight for long periods all at once.
2. Symptom: Dry leaf tips or withered leaf edges
Solution: This is likely due to over-fertilizing. So you should lengthen the interval between fertilizing so the mosquito plant gets balanced nutrients, and the leaves will gradually recover.
How to Grow Potted Mosquito Plants and What to Do When the Leaves Turn Yellow
The mosquito plant, also known as scented geranium (Pelargonium graveolens), is a perennial herbaceous or shrubby plant in the Geraniaceae family, genus Pelargonium. It is widely popular because the plant has a volatile fragrance, with a variety of scents including rose, citrus, mint, coconut, cardamom and various fruit flavors. It can be used to make essential oil and also has very high ornamental value. Let's take a look below at how to grow potted mosquito plants!
Growth Habits of the Mosquito Plant
The mosquito plant likes warmth and tolerates drought, is not cold-hardy, and fears waterlogging. It has low water requirements and grows well in neutral or slightly alkaline soil. Its growth requires plenty of sunshine, and light has a good effect on its development and on increasing its essential oil content. Areas with 1100-1300 hours of annual sunshine can basically meet its growth needs. Cultivation requires deep, loose-textured, humus-rich fertile sandy or loamy soil, while heavy clay soil and low-lying, poorly drained land are not suitable for cultivation.
Propagation Methods for the Mosquito Plant
1. Sowing: In early March, sow the seeds into clean fine sandy soil at a depth of 3 cm. Four hours after sowing, water thoroughly, then keep the potting soil moist but not too dry or too wet. In early spring, place it indoors in a warm, bright spot at a room temperature of about 20°C; in about 1 month it will sprout and root, after which it can be transplanted.
2. Cuttings: The mosquito plant roots easily from cuttings in spring and autumn. In April, May, or September, October, cut sturdy shoots with terminal buds, 5-8 cm long, let the cut end dry, then insert for rooting, keeping 2-3 terminal buds. Provide shade and keep moist; roots will form and the cutting will survive in about 15-20 days. Once the cutting grows new leaves, it can be potted.
How to Grow a Potted Mosquito Plant?
1. Soil: The mosquito plant prefers neutral to slightly acidic soil. Seedlings grow extremely fast, so repotting is done more frequently during the seedling stage. Within 6 months, use a specially mixed growing medium of 6 parts peat soil, 1.5 parts vermiculite, 1.5 parts perlite and 1 part coal ash, with a slightly acidic to neutral pH. You can also buy a prepared commercial foliage-plant potting mix (pH 5.5-7) from a flower market. After six months, the plant is extremely adaptable and can be grown in any soil.
2. Temperature: The most suitable growing temperature for the mosquito plant is 10-25°C. It can overwinter safely above 0°C, and above 15°C it can normally release its lemon fragrance. The higher the temperature, the stronger the fragrance. Misting the leaves with an appropriate amount of water can keep citronellal being released continuously, making the mosquito-repelling effect even better.
3. Light: The mosquito plant likes conditions with plenty of sunshine, warmth and good ventilation. In spring and early summer, when light is not too intense, the pot can be placed in a spot with plenty of light so it receives sufficient sunshine, but in the hot seasons of midsummer and early autumn it should be placed in a shaded spot and kept out of strong direct light, otherwise the branches and leaves will get scorched.
4. Watering: The mosquito plant tolerates drought and fears waterlogging, so during growth, water should be controlled appropriately. Too much watering and excessive water content in the potting soil will cause leggy growth or root rot. In spring and autumn, when growth and flowering are vigorous, you can water a bit more, but it is still best to keep the potting soil moist. In winter, when temperatures are low and the plant grows slowly, water as little as possible.
5. Fertilizing: When growing the mosquito plant, besides applying enough base fertilizer, during the growing season, especially at peak flowering, apply a dilute liquid fertilizer once every 7-10 days. Diluted decomposed livestock and poultry manure is even better, or you can water with decomposed cake fertilizer solution. 3-5 days before fertilizing, water less or not at all; applying fertilizer when the potting soil is on the dry side is better for root absorption.
5. Pests and Diseases: Improper management of the mosquito plant can cause root rot or rot of stems and leaves, followed by leaf shrinkage and black spots, and then the whole plant wilts. This is caused by too much humidity, too high a temperature, and at the same time poor ventilation or too dense seedlings. You can spray fungicides such as chlorothalonil or carbendazim (800-1000 times dilution). But do not spray frequently.
What to Do When the Mosquito Plant's Leaves Turn Yellow?
1. Improper fertilizing: If you fertilize every day during the mosquito plant's growing season, and do not water right after fertilizing in spring, and sometimes fertilize only after a very long time, this habit will make the mosquito plant's leaves turn yellow. Fertilizing should follow the method of frequent light applications, which is good for the mosquito plant's growth. During the growing season, fertilize about once every 15-20 days. In summer, fertilize as little as possible or not at all, but be sure to water after fertilizing.
2. Improper watering: Leaves turning yellow and soon falling off is mostly caused by over-watering. Watering should follow the principle of alternating dry and wet. In summer, when temperatures are high, water less and do not fertilize, which is good for developing a strong root system and improving disease resistance. For home growing, rice-washing water can be used instead of ordinary water. Water thoroughly once every 3-6 days, but do not let water accumulate. Note: water when the soil surface of a small pot turns white, or when the soil 1 cm below the surface of a large pot feels moist. In the high temperatures of July and August, spray water frequently to cool things down and keep the surrounding environment humid, but do not let water accumulate in the pot.
3. Too large a temperature difference: The mosquito plant likes light. If a potted mosquito plant is kept indoors or outdoors for a long time, the large day-night temperature difference will also make the mosquito plant's leaves gradually turn yellow. The mosquito plant likes shade and cannot tolerate strong light during growth, especially in summer when shading must be strengthened; it can be planted under trees or in a shaded spot. For home potting, it is generally kept indoors in a shaded spot.
4. Pest and disease prevention: If humidity is too high, temperature is too high, and at the same time ventilation is poor or seedlings are too dense, pests and diseases will develop, which will also make the mosquito plant's leaves turn yellow or even cause root rot. The potted mosquito plant should often be placed outdoors to get some sun; if kept indoors, the indoor air should be kept circulating. At the same time, pesticides should be used regularly; you can spray fungicides such as chlorothalonil or carbendazim (800-1000 times dilution), but do not spray frequently.
How to Grow the Mosquito Plant and How to Rescue It When the Leaves Turn Yellow
In summer, many people are troubled by mosquito bites. Although many mosquito-repelling products are sold now, many people still feel they are not very safe. Knowing that the mosquito plant can effectively repel mosquitoes and help us avoid mosquito bites, everyone wants to ask how to grow the mosquito plant. During the growing process, some friends encounter the situation where the mosquito plant's leaves turn yellow. What is going on?
How to Grow the Mosquito Plant
How to grow the mosquito plant 1. Light. The mosquito plant likes plenty of sunlight, so during the day it can be placed outdoors to receive light, but be sure to provide proper shade to prevent its leaf tips or edges from being scorched by the sun.
How to grow the mosquito plant 2. Soil. The mosquito plant likes loose sandy loam, and soil that is acidic is best.
How to grow the mosquito plant 3. Water. Just keep the soil in the mosquito plant's pot moist, for example watering once a week. There is no need to over-water, to avoid causing the soil to become alkaline.
How to grow the mosquito plant 4. Repotting. The mosquito plant has a well-developed root system. If it grows too luxuriantly, you might as well transplant the new plants into other pots, or give the mosquito plant a larger pot.
How to grow the mosquito plant 5. Fertilizing. You can apply a compound fertilizer to the mosquito plant once every 15-20 days, using soil application rather than spraying directly on the leaves.
Use: At night when there are many mosquitoes, move the mosquito plant into the room and sprinkle a little water on its leaves so the leaves release citronellal to drive away mosquitoes.
How to Rescue the Mosquito Plant When Its Leaves Turn Yellow
Yellowing leaves are a pain point in growing potted plants. Many wrong care methods can cause leaves to turn yellow and dry up. So when the mosquito plant's leaves turn yellow, how should you handle it correctly?
Symptom 1: Sudden leaf drop over a short period
The cause is too rapid a temperature change or insufficient light. The correct approach is to place the mosquito plant in a sunny spot to get more sun, and make sure the light exposure time is increased gradually; it should not be placed in direct sunlight for long periods all at once.
Symptom 2: Leaves turn yellow and soon fall off
The cause is over-watering. The correct approach is to reduce the amount and frequency of watering, and just keep the soil moist; pay even more attention in winter.
Symptom 3: Dry leaf tips or withered leaf edges
The cause is over-fertilizing. The correct approach is to lengthen the interval between fertilizing so the mosquito plant achieves balanced nutrients, and the leaves will gradually recover.
Symptom 4: Large areas of leaves turn withered and yellow. The cause is infection by a yellowing-leaf pathogen. The correct approach is to cut off the yellow leaves and spray fungicides such as chlorothalonil or carbendazim, while also increasing light exposure.
How the Mosquito Plant Works
The mosquito-repelling geranium generally shows its mosquito-repelling effect when it has more than 20 leaves. Using a small spray bottle to spray water on the leaves (especially the underside of the leaves) will make the mosquito-repelling effect even better.
Through the above sharing, I believe everyone now knows how to grow the mosquito plant and how to rescue it when its leaves turn yellow. In daily growing of the mosquito-repelling geranium, it is also necessary to maintain a suitable temperature, water and fertilize at the right times, and give sufficient light, so that it can grow better.
