Yellowing of Cymbidium leaves may be caused by too much sunlight. At this time, first use scissors to cut off the yellowed leaves on the plant, and then move it to a place without strong light to raise it.
It may also be caused by too low temperature. At this point, move it to a place where the temperature is between 18-25°C and wait for it to recover. It may also be caused by lack of moisture. At this time, it is necessary to water the flower soil completely first, and then increase the frequency of watering appropriately to add water to it.
First, the light is too strong
1. Reason: Except for a few varieties such as Cymbidium, most Cymbidiums do not like strong light exposure. If you grow them in a place where the light intensity is very high, it will cause their leaves to be sunburned by the strong light and turn yellow.
2. Treatment method: At this time, the completely yellowed leaves on the plant should be cut off with scissors. Then, move it to a well-ventilated place with no bright light, or use a shade net to shade it. After some time, it can be restored.
Second. The temperature is too low
1. Reason: Cymbidiums like warmth and are not particularly cold-resistant. If the plant is kept in a place where the temperature is particularly low for a long time, it will cause it to grow poorly and its leaves will turn yellow.
2. Treatment method: first move the Cymbidium to a place where the temperature is between 18-25 °C, and then appropriately increase the time it receives light, and wait for it to recover.
Third. Lack of moisture
1. Reason: If you do not water the Cymbidium for a long time, it will lack water, and it may also cause its leaves to turn yellow.
2. Treatment method: At this time, water it in time. Water the soil thoroughly first, but do not allow water to accumulate in the soil. Then increase the frequency of watering appropriately to add water to it.
