What is the reason for the yellowing of orchid leaves?

1. Fertilizing too much, exceeding the demand of the plant, the leaves will appear bright and uneven after fertilization, and then the roots will show 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.

2. The soil has not been turned over for a long time, and the soil has solidified when all the nutrients in the basin have been 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. Hanging orchids belong to semi-shade flowers, but they also need light, so they should have 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.

What is the solution to the yellowing of hanging orchid leaves?

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.

2. The yellowing of the leaves of Cymbidium may also be caused by not turning the pot 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. At this time, we should loosen the soil and control moisture in time. Fifth, it is impervious to water for a long time. The roots of Cymbidium lose water, and the lower old leaves turn yellow. It should be watered thoroughly to keep the basin soil warm and moist.

There is a certain reason why the leaves of Cymbidium are yellowing, so we must find out the reason why the leaves of Cymbidium are yellowing in time, and find the corresponding solution to treat Cymbidium, and return a beautiful and healthy Cymbidium to itself.
