What if the leaves of potted Dendrobium turn yellow?

Dendrobium has a very high medicinal value, which is self-evident, and things are rare. As for how to grow this rare plant well, many people also take great pains, especially as a potted plant. Many potted friends always encounter this or that problems in the process of growing and cultivating Dendrobium, such as the phenomenon that the leaves of Dendrobium turn yellow.

The phenomenon of yellowing of leaves in potted Dendrobium is very common, so what should we do when this happens? First of all, we have to find the cause of the yellowing of the leaves of Dendrobium, and then prescribe the right medicine, and then apply it to manage and protect it, so that we can raise the potted Dendrobium well.

From the growth habits of Dendrobium, we can find that Dendrobium likes wet and semi-shady growth environment, so we need to create a cool and humid growth environment for it. If the environment is uncomfortable, it may cause growth problems.

1. Environmental discomfort

The moist soil environment is more conducive to the respiration of Dendrobium roots, and the semi-shady weather environment is more conducive to its growth. On the other hand, if the growing environment of potted Dendrobium is hot and dry, or even the light is too strong, it is easy to make its leaves yellowing. Therefore, a good growth environment is a prerequisite for the normal growth of potted Dendrobium, so we should provide a good growth environment for potted Dendrobium as much as possible.

II. Excessive drought and flood

Although Dendrobium likes wet environment, it does not mean that too much water is needed. If stagnant water appears in the basin for a long time, it will cause the root system of Dendrobium to rot. Now that there is a problem with the root system of the plant, the yellowing of its leaves is inevitable. In fact, once the leaf yellowing occurs, there is no need to panic. If the stems and roots of the plant have not yet withered and rotted, it may be restored as long as watering is controlled. On the contrary, if the basin is short of water for a long time, there will also be yellow leaves, which should be replenished in time.

Third, the temperature is too high

Because Dendrobium likes the warm and humid semi-shade environment, if the temperature is high and the direct sunlight is too strong, which is not conducive to the respiration of Dendrobium roots, it is bound to cause the yellowing of leaves. Especially in the hot weather in summer, Dendrobium generally stagnates, so in addition to avoiding direct light and high temperature, it is also necessary to create good ventilation conditions for plants, which can avoid or reduce the phenomenon of yellow leaves. It can also avoid or reduce the phenomenon of falling flowers and buds.

IV. The problem of basin soil

Most of the roots of Dendrobium are aerial roots, so they are sensitive to basin soil. if the soil medium is uncomfortable, or too much fertilizer is applied in the soil, it will lead to root problems and may be fatal in serious cases. Therefore, we must be careful in soil preparation, recommend the use of fermented completely mature bark, plant shavings, moss and other media to avoid the use of media containing bacteria, so as not to affect the normal growth of plants. At the same time, we can also ingest appropriate amount of phosphorus and calcium for the plant to promote root germination and growth, and make the plant grow more robust.

Of course, in addition to the above main reasons, the plant may also appear yellowing between the old leaves, which is mainly due to the lack of magnesium in the basin soil; if the new leaves and young leaves appear yellowing, it is mainly due to the lack of zinc. Specific lack of what caused the yellow leaf phenomenon, we should explore and summarize more in practice.
