The banyan tree likes the light, and enough light can make it grow luxuriantly. But if it is placed in a dark place indoors for a long time, its leaves will blacken because of insufficient photosynthesis.

Solution: it is very simple, move it to the indoor semi-shade, and put the right amount in the sun to bask in the sun.

2. The temperature difference is too large.

Banyan tree is sensitive to temperature, it is suitable to grow in places with small temperature difference between day and night, otherwise it is not suitable for banyan tree growth. It is understood that once the temperature difference between day and night is more than 10 ℃, banyan trees will have large areas of yellow leaves and black leaves.

Solution: in the maintenance of banyan tree, do not often move the flowerpot, and put it in a ventilated and transparent position, timely shade in summer, timely warmth in winter.

3. Overwatering

The banyan tree likes a humid environment. In its peak growing season, we should water it frequently and keep the basin soil moist. However, watering should not be too much, otherwise it will lead to stagnant water in the basin, which will not absorb oxygen and isolate the nutrient absorption of the plant. After a long time, the leaves of the plant will certainly turn black.

Solution: if the leaves of the banyan tree are black, first observe whether the roots are rotten, if not, put it in a ventilated place to allow rapid water loss; if the roots are rotten, you need to cut the rotten roots and cut them off. Then soak in disinfectant and replant it.

4. Improper fertilization

Banyan like fertilizer, the growth process needs adequate nutrients, but we must pay attention to fertilization, not too much and not too thick, otherwise it will cause harm to the growth of banyan, and then the leaves may turn black.

Solution: timely irrigation to dilute the fertilizer, and then flow out from the bottom of the basin; if the root burns, you also need to cut off the rotten root, change the pot soil, and replant. After that, fertilizing is reduced or not applied in winter, and once a month in other seasons, choose thin fertilizer and water, preferring light to thick.

5. Diseases and insect pests

In addition to the above points, there is another reason for the blackening of banyan leaves, that is, it is attacked by diseases and insect pests. In the environment of high temperature and humidity, scale insects and aphids often appear if they are not properly maintained. When the disease occurs, the leaves appear black spots and black powdery substances, causing the plant to induce soot disease.

Solution: clean the disease spot with brush and spray insecticide in time. As for what kind of medicine to spray, there is a detailed introduction in the pest control of banyan tree.

There are many species of scale insects, such as wax powder scale, tortoise wax scale and so on, which are often harmful to banyan trees. they are mainly parasitic on leaves and fresh branches and absorb plant nutrients.

Control method: if the leaves of banyan trees are found to be yellow, they should be checked to see if they are insect insects. If a small amount of scale insects are found, they can be washed away with water in time; if there are many scale insects, the medicine can be sprayed after manual removal, and the agent can be used to kill scale 800-1000 times, and the control effect can be achieved at one time.

2. Banyan aphids

In addition to shell insects, aphids are also one of the insects that attack banyan trees. The insect has a double thorn sucking mouth, which often gathers on the tender shoot and the back of the leaf absorbs plant juice, which makes the plant grow slowly. At the same time, a large amount of honeydew discharged by aphids can induce coal fouling disease and seriously affect photosynthesis.

Prevention and control methods: when a small number of pests are found, wipe them with clean water or soapy water with cloth to remove the insects and continue to spread; when there are many aphids, after manual cleaning, 40% omethoate 1000 times or 50% dichlorvos 1000 times solution should be sprayed for prevention and control, once every 7 seconds and 10 days, and the effect is excellent for 3 consecutive times.

In fact, red spider is one of the most common pests in banyan trees. Under the condition of high temperature, banyan trees are easy to give birth to red spiders if they are not properly maintained, and they often gather a large number of leaf spines to absorb juice. After being attacked by the red spider, the leaves of the plant will appear yellow spots, and in serious cases, the banyan tree will lose its leaves.

Prevention and control methods: the red spider is the most harmful from May to June every year. Spray the insecticide in time when it is found, choose 1000 times EC of phenyledalin, spray once every 10 days, and then completely eliminate it after 3-4 times.

Prevention and treatment: when the above symptoms are found, remove the diseased leaves in time and burn them centrally to reduce the source of the disease. At the initial stage of the disease, spray 70% manganese zinc wettable powder 400 times, once every 10 days, 3 times 4 times in a row, the prevention and control effect is good.

5. Banyan soot disease

In the environment of high temperature and humidity, scale insects and aphids often appear if they are not properly maintained. When the disease occurs, the leaves appear black spots and black powdery substances, causing the plant to induce soot disease.

Control method: clean the disease spot with brush and spray insecticide in time, according to the above pest control methods. In addition, in peacetime, it is necessary to strengthen maintenance, reduce air humidity and strengthen ventilation.

Generally speaking, the effect of the banyan tree is good, and it is easy to raise, so it is very suitable for keeping indoors.
