What to do when Chinese fan palm leaves turn yellow? Apply light fertilizer, control temperature, replenish water, provide shade, and prevent pests and diseases

The Chinese fan palm (Livistona chinensis) is a landscaping plant with high ornamental value, and it can be seen in many regions of China. However, even a plant with the highest ornamental value will have its overall beauty affected if yellowing occurs. So what should be done when Chinese fan palm leaves turn yellow? Below, the editor will walk everyone through it.

1. What to do when Chinese fan palm leaves turn yellow: find the cause

If you want to know what to do when Chinese fan palm leaves turn yellow, first you need to know what causes this phenomenon. Only after knowing the cause can you solve the problem accordingly. During ordinary cultivation, too little watering or too strong light are among the causes of this phenomenon. As for how to solve it? Below, the editor will walk everyone through it.

2. Causes of Chinese fan palm leaves turning yellow (with solutions)

1. Improper fertilization

In the process of cultivating Chinese fan palm, if we do not fertilize for a long time or apply concentrated fertilizer, these are among the causes of its leaves turning yellow. If it is not fertilized for a long time, it will dry up and turn yellow due to insufficient nutrients, while applying concentrated fertilizer can easily burn the plant.

Solution: During the growth process of Chinese fan palm, we generally only need to supplement fertilizer once before the Spring Festival, at the Dragon Boat Festival, and at the Mid-Autumn Festival according to the season. When fertilizing, remember to first dilute the fertilizer with water and maintain the principle of light fertilizer applied frequently, so that it can absorb it better.

2. Temperature too low

During the growth process of Chinese fan palm, its requirements for environmental temperature are very high. This plant is relatively not cold-tolerant. If we do not control the temperature well during cultivation and the environmental temperature is too low, it can easily cause the leaves of Chinese fan palm to turn yellow, and too low a temperature can also easily freeze and even kill the plant.

Solution: During the growth process of Chinese fan palm, it is very important to let it grow at a comfortable environmental temperature. Its suitable temperature is between 18-26°C, and after mid-October each year we also need to move it indoors to overwinter, and the indoor temperature should be kept no lower than 5°C.

3. Too little watering

In the process of cultivating Chinese fan palm, especially after it enters the growth period, its demand for water is very high. Especially in summer, if it is not watered for one day, its leaves will wilt and turn yellow, and long-term water shortage can also cause the plant to wither and die.

Solution: If the problem is caused by too little watering, we should not immediately pour in a large amount of water; it should be done gradually, because watering too much at once can easily cause root rot in the plant. Generally, in spring and autumn, watering once every 2-3 days is enough, while in summer it needs to be watered every day to maintain soil moisture.

4. Light too strong

Chinese fan palm is a light-loving plant. If the light in spring and autumn is relatively suitable, we can keep it outdoors to receive light all day. However, it is relatively afraid of strong light, so after summer arrives it still needs shading. Otherwise, if the light is too strong, it can easily scorch the plant and cause Chinese fan palm leaves to turn yellow.

Solution: If the problem is caused by too strong light, we should promptly move it to a semi-shaded place indoors for cultivation. After cultivating it this way for a period, the leaves of the plant will slowly turn green again.

5. Pest and disease infestation

During the growth process of Chinese fan palm, if we do not care for it properly, some pests and diseases and other undesirable phenomena can easily appear. Such problems are extremely harmful to the plant, not only affecting its ornamental value, but also causing Chinese fan palm leaves to turn yellow and dry up.

Solution: When problems such as pests and diseases appear, we must deal with them promptly. If the time is dragged out, the harm to the plant will be great, and handling it will also be more troublesome. For specific control methods, everyone can refer to the article on pest and disease control for Chinese fan palm. The editor will not repeat them here.

What to do when Chinese fan palm gets insects: pest and disease control for Chinese fan palm / 2 pests, 2 diseases

In the process of cultivating Chinese fan palm, what we least want to encounter is pests and diseases. Such problems are extremely harmful to the plant, not only affecting its ornamental value, but in severe cases also causing the plant to wither and die. So what should be done when Chinese fan palm gets insects? How should pest and disease control for Chinese fan palm be done? Below, the editor will walk everyone through it.

1. What to do when Chinese fan palm gets insects: find the cause

If you want to know what to do when Chinese fan palm gets insects, first you need to know what kind of insect it is. Only then can we carry out targeted treatment for different pests and diseases, because the treatment methods for each pest and disease are different. The details are introduced below, and interested friends can take a look.

2. Pest and disease control for Chinese fan palm (pests)

Stem borer

The stem borer is a pest of the order Lepidoptera. Its main harm to Chinese fan palm is to the young seedling heart leaves, thereby causing dead heart. If we do not promptly carry out targeted treatment, it will also gradually gnaw at the lower part of the plant and cause the whole plant to die.

Control method: When dealing with this Chinese fan palm pest and disease, we can use an 800-1000 times dilution of omethoate or 21% fenvalerate emulsifiable concentrate at 2000 times to directly spray and kill the pest.

Aphid

Aphids are one of the most destructive pests on Earth and are harmful to many plants, and Chinese fan palm is one of them. The damage caused by this pest is mainly that adults and nymphs suck the sap of leaves, stems, tender heads, and tender ears, thereby causing a large loss of nutrients in the plant and the appearance of withering.

Control method: When dealing with this Chinese fan palm pest and disease, we can use a 50% pirimicarb wettable powder 3000 times dilution or 2.5% fenpropathrin emulsion 3000 times dilution to spray and kill it.

3. Pest and disease control for Chinese fan palm (diseases)

Leaf spot disease

Leaf spot disease is a common plant disease, and its peak incidence is generally in spring and autumn. When it occurs, many oval brown spots appear on the leaves of Chinese fan palm, and as time goes on the spots gradually spread and the color slowly deepens, finally causing the plant to be unable to carry out photosynthesis and die.

Control method: For this Chinese fan palm pest and disease, we can use a 20% silylazole · prochloraz 1000 times dilution to spray the diseased plant. Generally, spraying once every 7-10 days, and after 2-3 times it can recover.

Leaf blight

Leaf blight is a relatively common disease of Chinese fan palm, mainly threatening its leaf margins, leaf tips, and other areas. When it occurs, many irregularly sized spots appear on the leaves, and as time goes on they gradually spread, finally causing the plant to wither and die.

Control method: When dealing with this disease, leaf blight, we can use a 50% thiophanate 1000 times dilution to spray the plant. Generally, once every 10 days or so, and after 1-2 times it can recover.
