2. Causes of yellow orchid leaves
Yellow orchid leaves are a very common disease. The main cause of this condition is due to improper tree care and environmental impacts. Join us to find out the causes of yellow leaf disease in orchidsfoundthe most suitable prevention and treatment methods.
Due to direct exposure to sunlight
Orchids usually like to live in cool environments with adequate light and humidity. Each type of orchid will suit different care regimes and living temperatures. However, almost all types of orchids do not like to be exposed to direct sunlight.
In the dry season, when exposed to sunlight for too long and at high ambient temperatures, orchids will easily have yellow leaves or even sunburn. If this condition is not corrected, the growth process of the plant will slow down, become stunted, and the aesthetic value of the orchid will be lost.

Low ambient temperature affects
Not onlyaffectedBecause the ambient temperature is too high, orchids placed in environments with too low temperatures are also susceptible to yellow leaf disease. Orchids can live and grow very well in environments with temperatures around 18 to 35 degrees Celsius.
However, when the temperature drops low in winter or on rainy days below 17 degrees Celsius, orchids cannot grow. This condition makes the orchid unable to photosynthesize and in a short time will cause the orchid’s leaves to turn yellow.
There is a problem with the orchid’s root system
Roots are important parts to maintain plant life. This is the part that provides nutrients, water and helps the orchid stick to the substrate. If the root system has problems, the plant does not receive enough water and nutrients, and the orchid’s leaves will turn yellow.
Orchid roots are often susceptible to attacks by fungi and pests. The cause is because the amount of water is too much, the substrate environment is wet or the substrate contains harmful pests. Therefore, it is very easy to irrigate with enough water, avoiding excess or lack of waterorchid leaves yellow.

Orchids are seriously lacking nutrients
One of the main reasons why orchids have yellow leaves is lack of nutrients. Orchids need to be fully supplemented with nutrients. Depending on the type of orchid, the amount of nutrients needed is different. If one of the nutrients is deficient such as zinc, nitrogen, iron, manganese, etc., the plant will grow slowly and be susceptible to disease.
Besides chemical fertilizers, biological fertilizers are becoming a very popular product line. You can choose biological fertilizers suitable for orchids to care for, helping the plant have enough nutrients to grow healthily.
The orchid is infected
Leaf rot or anthracnose is one of the common diseases that causes yellow leaves in orchids. Bacterial leaf rot diseasecaused.When infected, yellow, black or brown spots will appear on orchid leaves. Over time, the spots will spread around, causing the leaves to soften and smell rotten.
Anthracnose is caused by a type of fungus. This fungal disease is often found in royal orchids. They doorchid leaves yellowand gradually withered. Over time, the tree will die if appropriate treatment is not given.

Some other causes cause yellowing of orchid leaves
Besides the causes mentioned above, yellow orchid leaves can also be caused by a number of other reasons such as: yellow orchid leaves due to changes in habitat, orchids change leaves to flower, people fertilize the orchids too much or the orchid growing medium accumulates too much salt.
Orchids only need a sufficient amount of nutrients. If you use too much fertilizer and stimulants, orchids will easily experience fertilizer shock or drug shock. The sign of this condition is that the whole orchid turns yellow and wilts. The tree trunk is no longer as shiny as before.
Salt accumulation in the substrate occurs when you plant orchids and fertilize the plants for a long time. The excess salt inside will accumulate day by day, causing the orchid roots to deteriorate. This causes the orchid leaves to become shriveled and yellow.

A good way to help prevent yellow leaf disease in orchids
Orchids with yellow leaves, if not treated promptly, can die. Therefore, to prevent this situation from happening, people should apply some good ways below:
- Watering properly: We should only water plants in the morning or cool afternoon. In particular, watering in the morning is the most reasonable because this time the plants have time to absorb water before the environmental temperature rises. On the other hand, when watering, you must be even-handed and not let the plant become waterlogged. In fact, orchids need moist soil, but must have good drainage.
- Fertilize properly: Instead of using chemical fertilizers or homemade fertilizers, people should use specialized fertilizers to fertilize orchids. Prioritize choosing microbial organic fertilizer with balanced nutritional content: N, K, Fe so that plants can grow healthily. Fertilize periodically and in accordance with each stage of development.
- Make sure there is enough light: Orchids only like light light, so absolutely do not place the orchid basket in direct sunlight. Thus, the leaves will burn and turn yellow. Placing the orchid basket near a window with curtains or under the shade of a tree is most appropriate.
- Maintain appropriate temperature and humidity: The ideal temperature for orchids to grow is 20 to 30 degrees Celsius. Ambient temperatures that are too high or too low both affect the growth of orchids. In terms of humidity, orchids are suitable for humidity levels from 50 to 70%. If the environment does not ensure humidity, you can use a humidifier or place the orchid pot on an ice tray.
- Regularly check plants for diseases: Orchids are plants that are sensitive to the environment and pests. It is susceptible to attack by mealybugs, red spider mites or fungal diseases. So remember to check leaves and roots regularly to detect diseases early. For peace of mind, people should use natural pesticides to spray plants to prevent diseases: diluted chili or garlic solution…
- Take care of the tree periodically: We will prune away withered and yellow leaves so they do not spread to other leaves. Clean the plant pot and change the soil for the plant if there is mold or bacteria accumulation. After treatment, plants must apply a special nutritional regimen to speed up the recovery process.
