How to water Dendrobium orchid in pot? what if the leaves of Dendrobium turn yellow?

Dendrobium is a famous orchid plant, its flower posture is beautiful and noble, its color is elegant and beautiful, so it is deeply loved by everyone. Many people like to raise Dendrobium orchid potted plants at home, but they need some maintenance skills and patience for this kind of flowers, so how to water and fertilize potted Dendrobium orchids? Let's learn about the maintenance skills of Dendrobium together with the editor.

How to water potted Dendrobium

In spring, summer and autumn, it is better to water at 9-11:00 in the morning. When the summer temperature is higher than 30 ℃, we should pay attention to ventilation and moisturizing, not at high temperature. And it is necessary to turn on the circulating fan after watering to dry the water on the blade as soon as possible to avoid disease.

When the winter temperature drops below 10 ℃, the plant will enter a certain dormant period and can no longer be watered. If the winter temperature exceeds 10 ℃, watering can be carried out properly. The watering time should be scheduled for sunny days.

When there is too much water, the growth of the plant will become slow, and the roots are prone to necrosis. You can increase the air in the substrate by stopping watering, and start watering after the plant resumes growth.

What if the leaves of Dendrobium turn yellow?

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

1. 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 an environment of high temperature, dryness and high direct sun intensity, the leaves will easily turn yellow, so the choice of environment is very important.

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

3. When the leaves of Dendrobium turn yellow, you must pay attention to it. If it is not treated in time, it will cause the whole plant of Dendrobium to dry up. Therefore, the main problem of yellowing of the leaves of Dendrobium should be solved gradually.

Treatment method of rotten Root of Dendrobium

1. Ventilation and humidity control to reduce rotten roots

The rotten roots of Dendrobium may be caused by a variety of reasons, which can be soaked with fungicides such as streptomycin and then replanted with a new substrate. To control the humidity of the matrix, pay attention to more ventilation, can reduce the phenomenon of rotten roots.

2. Improve the maintenance environment

Dendrobium likes a warm and humid environment, and the environmental humidity where it grows should be more than 80%. Growth will be poor in an environment where the light is too strong or too weak, the temperature is too high or too low, the soil is barren or the water retention capacity is poor.

3. Disinfection in time

Cut off the rotten root and disinfect the cut mouth quickly. In peacetime maintenance, we should pay attention to increase environmental humidity and apply less fertilizer. Be sure to breed in a semi-overcast environment to prevent direct sunlight and reduce the temperature as much as possible.

How to propagate Dendrobium

1. Ramet propagation

The so-called split propagation is to separate those plants that grow together and plant them separately, generally speaking, from the base of the tufted stems of the old roots, to minimize the damage to the root system as much as possible, and to form a separate plant with the main plant. For those Dendrobium with luxuriant growth and reproduction and high germination rate, ramet is a very suitable method of propagation.

2. Budding propagation

The old Dendrobium plants often grow some new buds at the top or base, and there will be roots on these new buds. In this case, it is very suitable to propagate by dividing buds. The specific operation method is to select the buds with more leaves and roots to be cut off from the mother plant.

3. Cuttage propagation

The cutting principle of Dendrobium is similar to that of general cutting. fresh Dendrobium is selected and cut into several sections, each containing 2-3 segments, and the previous incision is smeared with plant ash or properly sterilized. According to the growth direction of Dendrobium, insert the root into the substrate. Because the nodes are the places where new buds grow, they should be exposed as far as possible outside the matrix.

Through the above content, I believe you have a certain understanding of the maintenance skills of Dendrobium. Although the flowers are very beautiful when they bloom, there is a hard-working gardener behind the beauty. without this gardener, the flowers would not have bloomed so beautifully.
