Is it normal for Dendrobium candidum to have yellow leaves? What are the causes and treatment methods of yellow leaves?

1. Is it normal for yellow leaves to appear?

If it is the normal aging period of Dendrobium officinale, the appearance of yellow leaves is quite normal. This is natural metabolism. The old leaves will naturally turn yellow and fall off in the later stage of growth. In this case, there is no need to worry, just need to take good care of it. If it has just been transplanted to a new place, Dendrobium officinale will also have a natural period of yellowing and falling leaves. This is also a natural phenomenon and is very normal. If it is not due to these two reasons, the sudden appearance of yellow leaves may be due to maintenance problems, and the cause needs to be found and adjusted.

2. Causes and Solutions

1. Unsuitable substrate: Dendrobium officinale likes to grow in a loose and breathable substrate. If the substrate does not meet the requirements, it may cause yellow leaves and needs to be replaced with a new substrate in time.

2. Wrong temperature: It likes a cool climate environment. If the temperature is too high or too low, it will affect its growth and cause the leaves to turn yellow. The temperature must be maintained during growth and should be controlled between 10-15 degrees as much as possible.

3. The light is too strong: It likes to grow in a diffuse light environment and cannot withstand strong light. Once exposed to strong light, the leaves will turn yellow and fall off, so it needs to be moved to a diffuse light environment.

4. Improper watering: Lack of water and drought can cause yellow leaves, and too much watering can also cause water accumulation and yellow leaves. Watering should be done reasonably and the amount of water should be controlled.
