What should we do when leaves fall in winter? Unveiling the mystery of plant defoliation in winter and coping strategies.

Why Do Plants Shed Leaves in Winter? What to Do When Leaves Fall?Reasons for Plant Leaf Shedding1. Climatic factors: With the decrease in temperature and the shortening of daylight hours in winter, plants adapt to environmental changes by shedding leaves to reduce water evaporation and nutrient consumption.2. Physiological factors: As plants grow, leaves gradually age and lose their photosynthetic ability. To maintain nutritional balance, plants actively shed these old leaves.3. Soil factors: Issues such as insufficient soil moisture, lack of nutrients, and high soil salinity and alkalinity can also cause plant leaf shedding.What to Do When Leaves Fall in Winter?1. Keep the soil moist: Although the soil moisture evaporation is slow due to low temperatures in winter, plants still need water. When watering, be sure to do so moderately to avoid waterlogging, and you can use materials like plastic film or straw to keep the soil moist.2. Fertilization: Although plant growth is slow in winter, they still require nutrients. You can apply some compound fertilizers, such as diammonium phosphate and sulfate potassium, to supplement the necessary nutrients for the plants.3. Pruning: Perform appropriate pruning on deciduous plants to remove diseased, weak, and dead branches, promoting plant growth. When pruning, be careful not to damage the main stem and major branches of the plant.4. Cold protection: In areas with lower temperatures, take measures to prevent plants from freezing. You can cover the plants with materials like plastic film or cotton blankets, or build greenhouses and greenhouses.5. Increase lighting appropriately: The daylight hours are short in winter, and the photosynthetic activity of plants is weakened. You can increase the plants' exposure to light using artificial light sources, such as fluorescent lights and energy-saving lamps.6. Pay attention to pest and disease control: Winter is a high incidence period for pests and diseases. It is necessary to observe the plant's growth condition in a timely manner and control pests and diseases as soon as they are found.Relevant Data and CommentsAccording to the report of the "Chinese Gardening" magazine, the phenomenon of plant leaf shedding in winter is common in the northern regions of China, which seriously affects the urban greening effect. Strengthening winter plant maintenance and improving plant cold resistance are of great significance for improving the urban ecological environment.Experts point out that plant leaf shedding in winter is a part of the natural growth process of plants. We should correctly understand it and take measures to deal with it. Strengthening plant breeding research and cultivating plant varieties with cold resistance and strong stress resistance is also the key to solving the problem of plant leaf shedding in winter.What to Do When Leaves Fall in Winter? By understanding the reasons for plant leaf shedding and taking corresponding maintenance measures, we can effectively deal with the problem of plant leaf shedding in winter. It is hoped that this article can provide useful references for you, allowing our plants to spend a warm winter.
