Causes of the curling of gardenia leaves in winter Methods to solve the curling of gardenia leaves in winter Gardenia, as a traditional ornamental flower in our country, are deeply loved by people for their fresh aroma and elegant attitude. In cold winter, many gardenia leaves curl, which not only affects the ornamental effect, but also causes problems for maintenance. This article will analyze the reasons for the curling of gardenia leaves in winter and provide corresponding solutions. Reasons why gardenia leaves curl in winter 1. Low-temperature environment Gardenia is native to southern my country and is sensitive to temperature. The winter temperature is low. Gardenia cannot adapt to the cold environment, causing the leaves to curl. Gardenia is suitable for growth. The temperature is 15-25℃, and when it is lower than 10℃, the leaves are prone to curl.
2. If the air is short of water and the air is dry in winter, the rate at which gardenia evaporates water will slow down. If watering is not timely, it will easily cause the leaves to curl. The moisture content in the soil in winter is low. If watering too much, it will also cause water in the roots., affecting the growth of gardenia.
3. Insufficient light in winter, the sunshine time is short and the light intensity is weak. Gardenia cannot fully synthesize, causing the leaves to curl. Insufficient light will also affect the flowering quality of gardenia.
4. The temperature of pests and diseases is low in winter, and the probability of occurrence of pests and diseases is relatively low. However, there are still some pests and diseases such as scale insects, red spiders, etc. that can invade gardenia, causing the leaves to curl. Methods to solve the problem of curling leaves of gardenia in winter 1. Increase the temperature In winter, place gardenia in a warm place indoors and keep the room temperature between 15-25 ° C. If conditions permit, use heating or electric heaters and other equipment to increase the room temperature.
2. Appropriate watering in winter slows down the evaporation rate of gardenia. Appropriate watering should be done to keep the soil slightly moist. The watering time can be chosen in the morning or evening to avoid watering during the high temperature period at noon.
3. Properly increase the light and place the gardenia in a sunny place to ensure 4-6 hours of light per day. If the light is insufficient, artificial light sources can be used to supplement the light.
4. Regularly inspect gardenia to prevent and control pests and diseases, treat pests and diseases in a timely manner, and use pesticides, fungicides, etc. to prevent and control, while maintaining plant ventilation to reduce the occurrence of pests and diseases.
5. Fertilization In winter, gardenia grows slowly, so the amount of fertilization can be appropriately reduced. In winter, compound fertilizers or organic fertilizers can be applied to supplement nutrients.
The main reasons for the curling of gardenia leaves in winter are low temperature, lack of water, insufficient light, diseases and insect pests. By increasing the temperature, watering appropriately, increasing light, controlling pests and diseases, and fertilizing, we can effectively solve the problem of curling of gardenia leaves in winter.
