Orchids are elegant ornamental plants, not only beautiful in shape but also rich in color, making them suitable for homes or offices to enhance the beauty of the environment. However, in daily care, we may encounter some problems, such as yellowing new leaves. So how should we deal with it?
Orchid Care Knowledge
1. Light: Orchids love plenty of sunlight, but too strong sunlight can cause leaves to turn yellow.
2. Temperature: The suitable temperature for orchid growth is between 20°C and 30°C. Too high or too low temperatures will affect the normal growth of the leaves.
3. Humidity: Orchids like a humid environment, but excessive moisture can easily lead to root rot.
4. Air Circulation: Orchids need air circulation to avoid water accumulation and hypoxia.
5. Fertilization: Orchids have high nutritional requirements, but excessive fertilization can also easily lead to yellowing leaves.
Reasons for Yellowing Leaves
1. Insufficient light: Orchids need plenty of sunlight; if the light is insufficient, it will cause the leaves to turn yellow.
2. Low temperature: Orchid growth requires a certain temperature; if the temperature is too low, it will affect the normal growth of the leaves.
3. Improper care: Improper care, such as overwatering or excessive fertilization, can lead to yellowing leaves.
4. Pests and diseases: Orchids are susceptible to pests such as aphids, powdery mildew, and spider mites, which can also cause leaves to turn yellow.
Detailed Treatment Methods
1. Observe the cause: First, you need to observe the cause of the yellowing leaves, whether it is insufficient light or low temperature.
2. Adjust the environment: For different causes, the environment needs to be adjusted, such as increasing the duration of sunlight exposure or raising the temperature.
3. Prevent and control pests and diseases: If it is found that pests and diseases are causing the leaves to turn yellow, timely prevention and control measures are needed.
4. Reduce fertilization: If the yellowing of leaves is caused by excessive fertilization, the frequency of fertilization needs to be reduced.
5. Prune in time: If the leaves have withered and turned yellow, they need to be pruned in time to avoid affecting the overall aesthetics.
Care Tips Sharing
1. Repotting: Orchids grow fast and need to be repotted regularly to avoid root hypoxia.
2. Regular watering: Orchids need to be watered regularly, but not too much to avoid waterlogging the roots.
3. Strengthen ventilation: Orchids need ventilation to avoid root hypoxia and leaf mold.
4. Keep clean: Orchids need to be kept clean, wipe the leaves and flower pot regularly.
5. Manage pests and diseases: Orchids are susceptible to pests and diseases and need to be managed in a timely manner to avoid affecting normal growth.
Orchids are elegant ornamental plants. In daily care, it is necessary to pay attention to factors such as environment, temperature, and humidity to avoid yellowing of leaves. If the problem of yellowing leaves occurs, it can be dealt with by adjusting the environment, preventing and controlling pests and diseases, and reducing fertilization. At the same time, regular repotting, regular watering, strengthening ventilation, and managing pests and diseases are also important skills for orchid care.
