Five ways to solve the problem of yellowing of white orchid leaves

The reason for the yellowing of the leaves of white orchids

Too much water

If the watering amount of white orchid is not well controlled, the basin soil is too dry or too wet, which will affect the normal growth of fleshy roots and lead to the emergence of yellow leaves.

The temperature is too high

When there is a problem with temperature control, too high temperature will make leaf transpiration abnormal and yellowing.

Too little light

White orchids need plenty of sunlight, otherwise they will inhibit the normal growth of the plant and produce yellow leaves.

Chlorosis

Chlorosis can easily lead to yellowing and shedding of leaves, and in serious cases, it will kill the whole plant.

Root rot disease

The harm of root rot is also more serious, which will make the roots black and rot, and affect the leaves from bottom to top.

The solution to the yellowing of white orchid leaves

Properly watered

The amount of water should be continuously adjusted according to the climate wettability and other aspects to ensure the normal and appropriate wettability of the soil.

Suitable temperature

In order to avoid excessive temperature difference, it is appropriate to maintain an average temperature of 5-10 ℃. When the temperature increases, special attention should be paid to the ventilation and ventilation of the culture environment and humidification of the dry air.

Plenty of light.

To ensure sufficient light, you need to put the white orchid in the courtyard or home balcony, windowsill and other places where you can see the light for a long time, but in summer, you should pay attention to avoid the direct light, exposure will also adversely affect the plant.

Prevention and treatment of chlorosis

Slightly acidic soil should be selected, a small amount of alkaline inorganic fertilizer should be applied, and when the disease occurs, ferrous sulfate (0.2%) should be sprayed on the leaf surface, the frequency is once a week, even spraying 3-4 times, or spraying alum fertilizer and water once a week, spraying 3-4 times continuously can alleviate the disease.

Root rot control

The occurrence of this disease is usually due to excess water, watering should be "no dry, no watering", and keep the soil loose and enhance its drainage. When there is more rainfall during the Meiyu period, timely rain protection measures should be taken for the plants; more broken tiles can be added at the bottom of the basin to speed up the flow of water and promote drainage.

The yellowing of leaves is actually very easy to solve, and each reason is closely related to our daily maintenance work. As long as we can do a good job carefully, there is no need to worry that the green in the basin will be far away from us.
