What if the leaves of Dendrobium turn yellow?

1. Environmental effect

Dendrobium is suitable for growing in a semi-overcast environment. If Dendrobium is planted in a dry environment for a long time, the leaves will easily turn yellow when exposed to strong light.

two。 Seasonal variation

The weather will affect the color change of the leaves of Dendrobium. When there is a seasonal change, it is necessary to increase the amount of organic fertilizer to help plants improve their resistance.

3. Control moisture

Potted Dendrobium should not be watered too much, otherwise the roots will rot, so the amount of water should be controlled in time; if the temperature is high, it is easy to make the soil dry and need timely watering to keep moist.

Now we all know what to do with Dendrobium after flowering, so we should cultivate Dendrobium well and not just watch its beautiful flowers.

Analysis on the cause of yellowing of Dendrobium leaves

Dendrobium is dry and afraid of stagnant water, especially when the new buds begin to germinate to the formation of new roots. But too wet, such as low temperature, it is easy to cause decay. When the weather is fine, dry and hot, in addition to watering, it is necessary to spray more water to the ground to maintain a high air humidity. What if the leaves of Dendrobium turn yellow? The following wed114 wedding network editor brings you the details of the causes of the yellowing of Dendrobium leaves.

What if the leaves of Dendrobium are yellow?

We know the environment in which Dendrobium is suitable to grow. Dendrobium likes humid and semi-shady environment, especially the wild Dendrobium will have higher requirements on the environment.

Method one

Only in a humid and semi-overcast environment will it be beneficial to the respiration of the air root of Dendrobium. If Dendrobium is always planted in a high temperature, dry, direct sun environment, the leaves will easily turn yellow, so the choice of environment is very important.

Method two

The influence of weather, seasonal change, will affect the color change of Dendrobium leaves, in the seasonal change should pay attention to the increase of organic fertilizer. Ensure the moisture level of the leaves and help the plant improve its resistance.

Method three

When the leaves of Dendrobium turn yellow, you must pay attention to that if it is not treated in time, it will cause the whole plant of Dendrobium to dry up, so it should be reasonable and suitable to gradually solve the main problem of yellowing of Dendrobium leaves.

Growth habits of Dendrobium

Often grow on tree trunks or rocks at 480-1700 meters above sea level. Like warmth. Moist and semi-overcast environment, not resistant to cold. The suitable temperature for growth is 18: 30 ℃, the suitable growth period is 16: 21 ℃, the dormant period is 16: 18 ℃, the night temperature is 10: 13 ℃, and the temperature difference is 10: 15 ℃. The daytime temperature exceeding 30 ℃ had little effect on the growth of Dendrobium, and the winter temperature was not lower than 10 ℃. Seedlings are susceptible to freezing below 10 ℃.

Dendrobium is dry and afraid of stagnant water, especially when the new buds begin to germinate to the formation of new roots. But too wet, such as low temperature, it is easy to cause decay. When the weather is fine, dry and hot, in addition to watering, it is necessary to spray more water to the ground to maintain a high air humidity. Evergreen Dendrobium can maintain sufficient moisture in winter, but deciduous Dendrobium can be properly dried to maintain high air humidity.

Dendrobium wild forest, but the cultivation is still more like light, 50% shading in summer and autumn, 30% shading in winter and spring is appropriate. If the light is too strong, the stem will be swollen and yellow, and the leaves will be yellowish green. But the sunshine is sufficient, the autumn flowering is good, and the flowering quantity is large.

The soil should use well-drained and breathable broken fern root, water moss, charcoal chips, broken tiles, perlite and so on, mainly broken fern root and water moss.

Dendrobium is the largest genus of Orchidaceae, including about 1500 species of plants, mainly distributed in tropical Asia and Pacific islands. There are about 63 species of Dendrobium in China and 39 species of Dendrobium for medicinal purposes. Domestic Dendrobium is distributed in the south of Qinling Mountains and Huaihe River. in terms of latitude, most species are concentrated between 15 °30 °N and 25 °12'N, and the northward species gradually decrease, and the northernmost boundary does not exceed 34 °24'N. From a vertical point of view, it is distributed at an altitude of 100 to 3000 meters above sea level. Dendrobium is a group developing from the center of tropical Southeast Asia to subtropical climatic conditions. Yunnan, Guangxi, Guangdong, Guizhou and Taiwan are the distribution centers of domestic plants.
