Do not throw away the yellow and withered leaves of the spider plant? Teach you how to save it easily.

First of all, we must understand the plant habits of hanging orchids: hanging orchids like warm and humid, not resistant to cold, avoid direct sunlight, avoid dry wind, can be cultivated indoors for a long time, its leaves cluster like flowers, evergreen four seasons, is a more famous foliage plant, known as "flowers in the air".

The second is to know why the leaves of Cymbidium turn yellow.

1. Fertilizing too much, exceeding the demand of the plant, the leaves will appear bright and uneven after fertilization, and then the roots will turn yellow due to malnutrition after partial decay. So at this time should stop fertilizing, more watering, or rice basin to wash the roots, change the new soil is also a very good way. It can be seen that the spatial soil liquid concentration is very important.

two。 The soil has not been turned over for a long time, and the soil is hardened when all the nutrients in the basin are exhausted. The deficiency of the three most important elements, nitrogen, phosphorus and potassium, makes the leaves gradually turn yellow. At this time, the soil should be changed or fertile loam and fertile water should be replaced in time.

3. Cymbidium is a semi-shade flower, but it also needs light, so you should keep at least 4-5 hours of light every day. Otherwise, the leaves will turn yellow when the chlorophyll decreases. The best way is to put it under an indoor incandescent lamp or on a balcony.

Finally, the problem of yellowing of hanging orchid leaves is solved according to the situation!

1. The yellowing of Cymbidium leaves may be due to excessive fertilization, which exceeds the requirement of the plant. At the beginning, the leaves were shiny and uneven, the roots rotted and the leaves were yellow. Should stop fertilizing, irrigate more water, or turn the pot to clean the root and replace the new soil.

two。 The yellowing of orchid leaves may also be caused by not turning the basin and changing the soil for a long time. The various nutrient elements in the basin soil have been exhausted, the three elements of nitrogen, phosphorus and potassium have not been replenished in time, the plant is lack of nutrients, and the leaves are yellow and thin. Fertile loam and fertile water should be replaced in time.

3. The yellowing of orchid leaves may also be caused by lack of light. Although the orchid is a semi-negative flower, at least four hours of astigmatism should be seen every day, otherwise the chlorophyll will decrease and the leaves will turn yellow.

4. The air permeability and water permeability of basin soil are not good, which leads to long-term stagnant water and difficulty in root respiration, so the leaves turn yellow naturally, so the soil should be loosened and moisture should be controlled in time.

5. Temperature: hanging orchids like warm weather, suitable for about 20 degrees to grow, winter need to pay attention to cold, can be moved to the house, do not put in the windy place in the window, so as not to freeze the leaves. If the temperature is too low, the orchid will stop growing, if it is less than 5 degrees, freezing injury may occur.

6. Prevention of diseases and insect pests: hanging orchids sometimes give birth to some shell insects, whitefly, etc., if found, should be timely disinfestation. When yellowing in front of the leaves is found, water application and fertilization should be strengthened.

After flower friends understand this, they can raise the hanging orchids at home very well, and the four seasons are in a good mood. Next, I will share with you some practical things needed to grow flowers. I hope I can also help you.

We say that hanging orchids are not only beautiful and generous, but also can purify the air and bring beautiful fresh air indoors, which is especially suitable for home or office pot farming. Generally, 1-2 pots of orchids in a room can kill 80% of the harmful substances in the room and absorb 86% of the formaldehyde in 24 hours. It can absorb all the carbon monoxide and nitrogen peroxide emitted by stoves, electrical appliances and plastic products, so the orchid is also known as "green purifier". And after learning these planting methods, the orchid will certainly be better!
