However, some people often have yellow leaves in the maintenance of white orchids. So why do the leaves of white orchids turn yellow? How to deal with the yellowing of white orchid leaves? The following section will explain them to you one by one.
The reason analysis and treatment methods of the yellow leaves of white orchid are as follows: 1. Too much water: too much water: too much or too little water, sometimes dry and wet, etc., the fleshy roots can't stand it, which will cause yellowing of leaves.
Treatment method: watering should be appropriate. After the basin soil is dry, the amount of water should not be too much when watering at one time, and it should not be out of the state of drought for a long time.
2、 Lack of light: white orchid like the sun, if the sun is too little, it will also cause poor plant growth, yellow leaves.
Treatment: white orchid is suitable for planting in the courtyard, balcony, windowsill and other places. It needs plenty of sunshine, but it can't be exposed to the sun. In summer, the sun is fierce, so we should pay attention to shading.
3、 Temperature is too high: white orchid leaves yellowing and temperature has a great deal to do, when the temperature is too high and sultry, the leaves will turn yellow.
Treatment method: the temperature should be stable, not too high or too low, 5-10 ℃ is the most appropriate, temperature rise, the environment is sultry, pay attention to ventilation, and strengthen humidity management.
4、 Yellow disease of iron deficiency: it is basicity of basin soil mainly. The reasons for the alkalinity of basin soil are as follows: first, the basin soil is alkaline; second, more alkaline inorganic fertilizer or water is applied, so the leaves gradually change from green to yellow white, and in serious cases, the leaves are brown and form local necrosis.
Treatment method: slightly acid soil should be selected for white orchid pot soil, and more alkaline inorganic fertilizer or water should not be applied. In case of yellowing disease, 0.2% ferrous sulfate should be sprayed on the leaves in time, once a week, 3-4 times continuously, or alum fertilizer water should be sprayed once a week for 3 or 4 times continuously to control the disease.
5、 Insufficient fertilization: long term fertilization, or not changing pots and soil for a long time, lack of nitrogen and other nutrients in the soil, resulting in weak branches and leaves, thin and yellow leaves. In addition, excessive fertilization will also cause new leaves to be thick and uneven, and old leaves will become brown and fall off.
In case of this phenomenon, it is necessary to remove the new soil and water the part of it.
6、 Root rot: excessive watering and failure to remove the accumulated water in the basin in a continuous rainy season will lead to black and rotten roots, yellow leaves and even fall off, leading to the death of the whole plant.

When Meiyu is young or there is too much rain, it is better to move to the eaves or indoor to avoid rain; when putting on the basin, more broken tiles should be added at the bottom of the basin to make the drainage unobstructed, and put the basin with bricks to accelerate the speed of water flow.

A small amount of loose soil should be padded in advance in the new basin (VAT), and then the water can be poured through to ensure stable planting.
2. The white orchid should be pruned regularly. Before entering the house, the dead branches, diseased branches, long and proud branches and over dense branches should be cut off to minimize the nutrient consumption of the plant. When leaving the room, the old leaves at the lower part of the branches can be appropriately removed to promote the growth of new branches. In addition, it is necessary to pay attention to the damage of aphids to the shoots, which must be controlled in time.
3. White orchid plant shape upright, with branches, graceful. It can be cultivated in the open courtyard in the South and is the backbone tree species in the southern garden. Northern potted plants can be used to arrange courtyards, halls and conference rooms. Small and medium-sized plants can be displayed in the living room and study.
