The leaves of Dendrobium candidum turn yellow. What should I do?

Dendrobium candidum not only has high medicinal efficacy, but also has good ornamental value. The pot of Dendrobium candidum which was originally pleasing to the eye may suddenly cause the phenomenon of yellow leaves or even the death of the plant due to various reasons. Then, there is no doubt that this is a kind of spiritual blow and torture for potted friends who like to grow Dendrobium candidum in pots.

So, why does Dendrobium candidum appear yellow leaf phenomenon? What are the reasons for the yellowing of leaves of Dendrobium candidum? How can we effectively prevent the yellow leaves or even death of Dendrobium candidum? Today, the editor will discuss with you to help you pull out the specific reasons, in order to help you raise your own potted Dendrobium candidum.

First, fertilization should be appropriate

Although Dendrobium candidum also likes adequate nutrients, the original does not like thick fat, nor is it resistant to fertilizer. If we apply a high concentration of fertilizer or raw fertilizer, or if the frequency of fertilization is too high, it will often lead to fertilizer burning the roots of the plant. Since the root of the plant is damaged, the ability to absorb and transport nutrients will decline or even disappear. Because the plant can not get the nutrients needed for growth in time, it will naturally sacrifice its stems and leaves to survive. Therefore, the leaves will turn yellow at the beginning of the plant stage.

Therefore, when we fertilize Dendrobium candidum, especially under the pot way, we must pay attention to control the concentration of less fertilizer and put an end to all raw fertilizer. It is usually based on light, thin organic fertilizer. In this way, the yellowing of leaves due to excessive fertilization can be avoided, so that the plant has sufficient nutrients to grow.

Second, temperature, light and humidity should be satisfied.

Dendrobium candidum prefers the growing environment with warm, weak light and relatively high humidity. As a potted plant, it should be placed in a place with good ventilation, warm and humid conditions and can receive scattered light. If the growth environment of the plant changes and becomes no longer suitable for its growth, then the plant is prone to the phenomenon of yellow leaves, especially when the humidity is not enough but the light is too strong.

Therefore, first of all, we need to create a more comfortable growth environment according to its growth habits and reasonably control watering, but we should often spray water and spray to keep moisture. Because Dendrobium candidum has high requirements for air humidity, it can ensure that there is enough humidity in its growth environment to maintain its normal growth.

Third, pick flowers and leaves properly

Many potted friends who like to grow flowers hope that their potted plants can grow luxuriantly, but for potted Dendrobium candidum, although it blossoms more beautifully, if it blossoms too much, it is easy to have a big impact on the normal growth of the plant, including yellow leaves. Mainly because the flowering period of Dendrobium candidum is relatively long, coupled with a large number of flowers, when it blooms fully, it will compete for a lot of nutrients for flowering, which will naturally reduce the supply of stems and leaves, so the stems and leaves will naturally grow worse.

Therefore, the phenomenon of yellow leaves is inevitable. After all, in the case of a large number of blossoms, nutrients are consumed too much and too fast, and if fertilization is not applied in time, the stems and leaves will be affected. At this time, we do not put some poor quality flowers and artistic conception withered yellow stems and leaves, so that it does not affect the ornamental nature of potted plants, but also can promote its growth.

Finally, let's talk about the natural yellowing of the leaves of Dendrobium candidum, which is the product of plant metabolism, so it is a normal phenomenon. Then, we only need to remove the yellow leaves in time to avoid their impact on viewing, but also save some nutrients.
