Because of its distinctive appearance, many people raise one-leaf orchid as a potted plant to decorate the environment at home. As some people do not understand the growth habits of one-leaf orchid, it is easy to have yellowing leaves during maintenance, so what should we do?

The reason for the yellowing of the leaves of Cymbidium

1. The light is too strong or lack of light during the maintenance of one-leaf orchid.

One-leaf orchid is a kind of plant that likes shade and is afraid of bright light. Its leaves are very broad and highly ornamental, which is the reason why many people like to maintain one-leaf orchid. Because some friends do not understand their habits, they keep them outdoors or indoors for a long time, no matter in the summer when the sun continues to shine or in the long-term rainy winter and spring seasons, they do not move potted plants. in this way, a leaf orchid will appear the phenomenon of leaf yellowing and scorching because of the strong light, and it will also appear the phenomenon of light, yellowing and wilting of the leaves due to the long-term lack of sunlight.

2. Excessive fertilization or long-term lack of fertilizer

This is also a mistake often made by many green plant novices, either thinking of growing fast and giving them thick fat, or buying it back and ignoring it and putting it there to kill themselves will not be fattened. If the fertilizer is too thick, it is easy to burn roots, then the leaves will be withered and yellow. If there is a long-term lack of fertilizer, the leaves will be light in color and grow slowly, and the old leaves will appear yellowing and falling.

3. Overwatering or long-term lack of water

Because one-leaf orchid likes to grow in a humid environment, many people watering too often during maintenance affects the air permeability of the basin soil, resulting in the yellowing of leaves.

The growth of plants needs not only nutrients but also water, especially in summer, when the temperature is high and the water evaporates quickly, if the leaves are not watered for a long time, the natural lack of water will lead to leaf yellowing and wilting.

4. Invasion of diseases and insect pests

Like other green plants, one-leaf orchid is prone to insect pests, especially red spiders, which are more likely to occur when the environment is too humid and unventilated, and the leaves will turn yellow once they are affected by insect pests.

Second, the solution to the yellowing of the leaves of Cymbidium.

1. The solution to the yellowing of leaves caused by improper lighting: if you keep it indoors for a long time, remember to keep it in a sunny and astigmatic place, but not on a balcony or windowsill where it is vulnerable to direct sunlight. In summer, it should be properly shaded and cooled down. If you can't see the sun for a long time in winter, you can move to the outside to bask in the sun.

2. The solution to the yellowing of the leaves of Cymbidium caused by improper fertilization: the principle of fertilization is determined according to the growth of the plant. If the growth is normal, there is no need for additional fertilization. If you find the phenomenon of slow growth, you can apply fertilizer appropriately. One-time fertilizer is not too much, too heavy, easy to be counterproductive, because if you can't eat a fat person in one breath, you will get bloated.

3. The solution to the yellowing of leaves caused by improper watering: watering is dry and wet, and the basin soil is too dry or too wet is not conducive to growth. If the leaves are yellowing at this time, you should see whether it is caused by too much watering or a long-term lack of water. Watering too much needs to replace the basin soil, re-transplant, long-term lack of water, then need to replenish water, do not irrigate too much at one time, but slowly from the edge of the basin soil, wait until the growth returns to normal before returning to water.

4. Diseases and insect pests lead to the yellowing of leaves: to prevent the invasion of diseases and insect pests is to keep the leaves clean for a long time, and usually pay attention to spraying water or cleaning leaves. Once it occurs and given treatment, so as not to affect healthy plants.

The above is the introduction of the reasons for the yellowing of the leaves and the solutions. If there is a similar situation during conservation, you can refer to it. If it is not, it may be the normal growth state of the plant, and it will return to normal after a period of time.
