What causes the splitting of orchid leaves
Today's life tip brings you the knowledge related to why orchid leaves split, including the causes and reasons for orchid leaf splitting. Next, the editor will introduce these to everyone.
1. Pest damage: Orchids can be threatened by pests during their growth. Some pests eat the leaves and flowers of orchids, severely affecting their growth. The most common pest during the growing period of orchids is scale insects. The main symptom of Lepidopteran insects on orchids is leaf splitting. This is because scale insects bite leaves from the inside out, causing the leaves to split in the early stages. Therefore, it's important to frequently check the growth of orchids and control scale insects in a timely manner if found. Create a good permeable environment for orchids to reduce the damage caused by pests.
2. Diseases: Orchids can be damaged by insects and are also affected by diseases. Common orchid diseases include leaf spot and downy mildew. The main symptoms of common orchid diseases are spots on the leaves, leading to leaf dehydration and drying, with the center of the leaves gradually splitting. Therefore, while preventing and controlling pests, more attention should be paid to disease prevention and control. We need to understand the common diseases of orchids to detect specific diseases in time. Then, apply the appropriate treatment to avoid the disease getting worse and causing more severe leaf splitting.
3. Fertilizer damage: Although orchids need appropriate fertilization during their growth, it is also necessary to supplement the nutrients in the fertilizer. However, it is important to control the amount of fertilizer during application. If the fertilizer is insufficient, the growth of orchids may be affected due to lack of nutrition, causing the leaves to turn yellow, dry, and split. Do not use too much fertilizer. Excessive fertilization can easily cause leaf splitting. Also, be careful not to let the leaves come into direct contact with the fertilizer, as this can easily burn the leaves. Therefore, it is important to fertilize reasonably to ensure the normal growth of orchids.
4. External factors: In addition to the above three points, there are some external factors that are the main causes of orchid leaf splitting. For example, improper handling during watering, fertilizing, and pruning can cause leaf splitting. If the leaves are flushed or excessively exposed to rain, it is very likely to cause leaf splitting. Therefore, when planting, ensure that orchids are in a well-protected area from wind and rain. When fertilizing, do not allow fertilizer to come into direct contact with the leaves to avoid burning them.
The above sharing on the causes of orchid leaf splitting and the comprehensive explanation of why orchid leaves split is hoped to be a starting point that can solve your problems in life.
