What is the reason why the leaves of the fortune tree turn yellow, and what is the reason why the le

The fortune tree is native to Central and South America, prefers warm, moist, sunny or slightly shady environments, and the suitable temperature for growth is 18 30. The temperature in winter should reach more than 5, otherwise it is easy to freeze damage. In the middle of winter, as long as the temperature remains at 18

Above, if the sun is sufficient, it can grow as usual. When the room temperature is lower than 8, damp, dry and not ventilated, the leaves are prone to water-stained patches, which are bronze and fall off. When the temperature is lower than 5, the leaves all fall, the shoots lose water and dry up, and the whole plant dies when it is serious.

Generally, they enter the room for wintering in November and leave the room after the "valley rain". The fortune tree has a strong adaptability to water, and will not cause waterlogging and drought when watered outdoors or indoors for more than 10 days. However, in winter, the potting soil should be avoided from moisture, and it is advisable to be slightly damp, otherwise the leaf tips are easy to dry and scorch, and even the leaves fall off.

If the room temperature is around 12, you can water it once a month. The Fortune Tree grows faster and has a well-developed root system, and is repotted every 2 years in late autumn or early spring.

The causes and treatment of the yellowing of the leaves of the fortune tree are as follows:

1. Reasons. 1. Improper temperature: It likes a high temperature environment and has poor ability to withstand low temperatures, so if the temperature is not controlled in winter, it will be frostbitten and the leaves will turn yellow. In addition, it can turn yellow when the temperature is too high in summer.

2. Insufficient light: it likes light, sufficient light can better promote photosynthesis, which is beneficial to the growth of branches and leaves.

3. Improper watering: excessive watering or long-term lack of water during maintenance will cause yellowing. Watering multiple roots can not absorb all of them, it will rot the roots and the leaves will turn yellow. If there is a lack of water, the soil will be compacted, the roots will not be able to absorb water, and the leaves will turn yellow.

2. Treatment methods.

1. Timely temperature control: When the temperature is low in winter, it should be moved indoors in time, and the temperature between 16 degrees and 18 degrees should be provided as much as possible, and the minimum temperature should not be lower than 5 degrees. In summer, when it is hot, move indoors and put it in a cool place.

2. Supplemental light: If it is caused by insufficient light, it is easier to solve it, just move it to a well-lit place as soon as possible, so that it can recover after a while.

3. Appropriate amount of watering: The appropriate amount of watering must be done during maintenance, and water cannot accumulate without water. Usually, it can be carried out according to the method of seeing dry and wet. If the water is severe, move to a well-ventilated area and allow the water to evaporate as soon as possible.

The cold tolerance of the fortune tree is very poor, if the temperature can not be well controlled in winter, and it is in an environment below 5 for a long time, it is easy to freeze, which will cause the leaves to turn yellow, and even dry up and fall. The temperature should be controlled as soon as possible to keep warm, and it is best to keep it warm at more than 10.

The fortune tree likes light, but it is not sun-tolerant, and if it is exposed to strong sunlight for a long time, it is easy to be sunburned, which will cause the leaves to turn yellow. It should be shaded or placed in a dark environment to recover slowly. Note that only astigmatism is acceptable.

Although the fortune tree has a certain drought tolerance, but if it is not watered for a long time, it is easy to cause yellow leaves due to lack of water, it should be replenished in time, it is best to water thoroughly, so that it can absorb enough water, pay attention, no matter when there can be no water accumulation.

If the soil is not changed for a long time, the soil compaction will hinder the root respiration, and it is easy to have yellow leaves. If this situation is caused, the soil should be replaced as soon as possible, and the soil is soft, breathable and slightly acidic.
