Remedy: if the banyan leaves are sunburned, the flower friends should move the banyan to the indoor half-shade in time, pay attention to ventilation, wait for it to recover, and then water it properly. After careful care for a period of time, the plant will return to health.

2. Improper watering

Too little watering: Qin leaf banyan likes a humid environment, so it needs enough water during its growing period. if it is not watered for a long time, or it has not been watered thoroughly, the leaves of Qin leaf banyan will become dim and dull because they cannot absorb water, and they will fall off as soon as they touch them. Remedy: need a small amount of watering and spraying (do not add too much at a time), wait until the leaves of figs no longer fall behind before turning to normal watering.

Overwatering: although Qin leaf banyan likes water, we should not water too much at one time, otherwise it will lead to stagnant water in the basin and eventually cause root rot, thus affecting the water absorption and feeding of the plant, and the leaves will easily fall off. Remedy: stop watering and often loosen the soil so that the soil is well ventilated, and then slowly return to normal watering.

3. Insufficient fertilization

5. Normal phenomenon

In addition to the above points, we should also consider whether it is a normal phenomenon. It is understood that the newly bought banyan leaves are easy to lose their leaves, and this is actually a very common thing, because although the figs have strong adaptability, they also need a process of adaptation to the new environment. During this period, it usually loses its leaves.

For Qin leaf banyan, you should have seen, it has broad leaves, beautiful plant type, is currently one of the most popular indoor potted plants. As an ornamental plant, what Qin leaf banyan fears most is the problem with its leaves, especially the yellow leaves, which gives them a headache. What about the yellow leaves of Qin leaf banyan? Here are some reasons why the leaves of figs turn yellow. Let's go and have a look.

First, Qin leaf banyan leaves yellow, looking for the cause

As a common foliage plant, the cultivation method of fir is not difficult, but because there are many newcomers, they often do not do well in light and fertilization, as a result, the leaves are fed yellow. As for the yellowing of Qin leaves and banyan leaves, first of all, we should not be in a hurry, but should calmly find the cause, and then aim at the solution. Let's move on to the details.

Second, the causes of yellowing of figs leaves and their solutions.

1. Environmental mutation

If the reason for the yellowing of Qin-leaf banyan leaves is that it is a newly bought potted plant, it should be due to great changes in the environment, and the plants do not adapt for a while and appear leaf yellow. in addition, if the flowerpot is often moved recently, or if the pot has just been changed, or if you put it next to the air conditioner to blow hot or cold air, the banyan may also have yellow leaves.

Solution: put the banyan plant in a well-ventilated, well-lit semi-shade and carefully maintain it for a period of time, and it will return to health.

2. Improper lighting

Lack of light: Qin leaf banyan likes light and grows well in an environment with sufficient light. But if you put it in a place with weak light for a long time, the photosynthesis of its leaves is less, nutrients are missing, and yellowing is inevitable. Solution: it can be maintained in a place where the light is good but not strong.

The light is too strong: in places with good light, the leaves of figs grow big and green, but in summer, if they are not shaded and hit by strong light, their leaves will turn yellow and wither. Solution: move to the indoor shade in time, slow for a while, then water the right amount, and then slowly increase the light.

3. Improper fertilization

Insufficient fertilization: Qin leaf banyan likes fertilizer, and sufficient nutrients can make its leaves big and green. Therefore, when people do not apply enough fertilizer, especially when the amount of nitrogen fertilizer is too low, the banyan leaves will be yellow because of poor growth. Solution: nitrogen fertilizer can be added, but not excessive application at one time, light fertilizer should be applied.

Excessive fertilization: although the large leaves of figs need a large amount of fertilizer, too much fertilizer is not allowed. Once too much fertilizer is applied, it is easy to cause the plants to burn roots, and the leaves will turn yellow and wilt. Solution: when the root burning is not serious, pour water to dilute the fertilizer and let it flow out along the bottom of the basin; if the root is rotten, you need to take off the pot, cut the root, and then change the pot soil to plant again.

4. Soil Alkalization

The yellowing of fir leaves may also be caused by soil. It is understood that Qin leaf banyan likes slightly acidic soil, and its leaves will turn yellow when it is in slightly alkaline soil, or when long-term irrigation of tap water leads to alkaline soil.

Solution: use pure water for daily watering, or leave tap water for a few days or bask in the sun for a few days, so as to avoid the problem of soil Alkalization. If the soil is already alkaline, the easiest way is to change the soil and make the plant refreshing again.

5. Diseases and insect pests

In addition to the above points, the reason why the leaves of figs turn yellow may also be that it is sick and grows worms. In daily maintenance, if the environment is not ventilated, the temperature is too high, coupled with improper maintenance, the banyan will suffer from diseases and insect pests, resulting in yellowing leaves.

Solution: move the potted plant to the ventilated place, and find out what kind of diseases and insect pests it is, and then solve the problem by spraying. As for what medicine to spray, you can refer to the pest control of Ficus chinensis.

Generally speaking, Qin leaf banyan is very easy to raise, but if you want its leaves to be green and not yellow, you must pay attention to light, water and fertilizer. Of course, don't worry when you find yellow leaves, just solve it according to the above method. With regard to the yellowing of Qin leaves and banyan leaves, this is the end of the editor's introduction, hoping to give you some help.

The skills of planting flowers in October

First, the light should be sufficient

Some light-loving woody flowers that bloom in summer, such as jasmine, Fusang, Jiuli incense, etc., should still be placed in a sunny place, so that the plants can fully receive light, so that the leaves can better carry out photosynthesis, provide nutrients in time, and promote the maturity of branches in the current year. so that it can survive the winter safely and ensure that flowers and leaves still flourish in the coming year. Potted flowers such as rhododendron, magnolia, cyclamen, poinsettia and crab claw orchid that bloom before and after the Spring Festival should also be placed in a sunny place and receive full sunshine, otherwise the flowering period will be postponed or even will not bloom. General foliage plants are more shady, can give some light properly, but to avoid noon strong light.

2. Water and fertilizer should be appropriate

In early autumn, especially in the first and middle of September, the temperature is still high and the transpiration of plants is large. Most flowers should be watered once a day or two, and the amount of water should be controlled and fertilization should be stopped from the middle to late September, so as to avoid rotting roots and growing branches and leaves. Affect overwintering. Some flowers that bloom before and after the Spring Festival, such as cyclamen, orchid, crab claw orchid, rhododendron, etc., have passed the dormant period and began to enter the peak growing season, so they should blossom continuously from autumn to the Spring Festival, and appropriately increase phosphorus and potassium fertilizer. to facilitate flower bud formation and bud flowering.

Third, pruning should be reasonable

In addition to flowers that bloom in early spring, most flowers, such as jasmine, crape myrtle and pomegranate, can be pruned in autumn and pruned at the end of autumn and early winter, so that plants can reduce nutrient consumption in winter, promote potted flowers to be strong, and bloom more in the coming year. Remove diseased branches, withered branches, over-dense branches and overgrown branches when pruning, so as to lay a good foundation for potted flowers to survive the winter.

IV. Disease and pest control should be thorough

Autumn is still the season with high incidence of diseases and insect pests, and plants are vulnerable to shell insects, red spiders, aphids, whitefly and other pests. Diseases include leaf spot, stem rot and so on. Before potted flowers enter the house, these diseases and insect pests must be treated thoroughly and never let them do harm to the house. If no diseases and insect pests are found, they can be sprayed to prevent them.

V. breeding should be timely

After the Beginning of Autumn, the temperature dropped, and some biennial grass flowers, such as pansy, carnation, melon and leaf chrysanthemum, hollyhock, etc., were good time to sow seeds. Sowing can be carried out from September to October, and pay attention to spraying water after sowing to keep the soil moist.

Perennial flowers with dense growth, such as peony and peony, should be propagated in time. For the bulb flowers that bloom before and after the Spring Festival, such as hyacinth, tulip, Zhu Dinghong, etc., we should pay close attention to the pot.

VI. The room should be entered in time
