The curling outward leaves can be caused by a variety of factors, including overwatering, too much fertilizer, pest and disease infestation, and lack of light. These factors can lead to root damage, abnormal leaf growth, or pests and diseases, which in turn can affect the health of the entire plant.
In order to effectively prevent the problem of outward curling of the leaves of the crane orchid, we need to take a series of measures. First of all, proper watering control is key. The need for water is high, but too much water can cause root rot, which in turn affects the normal growth of leaves. Therefore, we should follow the principle of "see dry but wet" to ensure that the soil is kept moist and avoid overwatering.
Secondly, fertilization is also an important part of preventing leaf curling. Orchids need adequate nutrients to maintain normal growth, but too much fertilizer can burn the roots, causing the leaves to curl. Therefore, we should follow the principle of "thin fertilizer and diligent application", apply fertilizer in an appropriate amount to avoid excessive fertilization and damage to plants.
In addition, pest control is also necessary. Pests and diseases can cause abnormal leaf growth and curling. We should regularly check the growth of Hewang orchid, detect and take prevention and control measures in time. Once pests and diseases are found, they should be carried out with appropriate agents in time to avoid deterioration of the condition.
Finally, lack of light is also a cause of leaf curl. Orchids need plenty of sunlight to maintain normal growth, and lack of light can lead to poor leaf growth and curling. Therefore, we should place the orchid in a sunny place to ensure that the plants can receive enough sunlight.
To sum up, the prevention and control of the outward curling of leaves requires us to start from many aspects, including reasonable control of watering, fertilization, pest control and adequate light. Through the implementation of these measures, we can effectively protect the health of Hewanglan and allow it to thrive.
