Reasons for the Cedrus叶子枯 in Winter Cedrus叶子枯 Maintenance Tips in WinterCedrus is a common garden plant in China, loved for its evergreen and beautiful shape. Many Cedrus trees show yellowing leaves in winter, which puzzles many maintainers. This article will unveil the reasons for the yellowing of Cedrus leaves in winter and provide corresponding maintenance tips to help solve this problem.
Reasons for the Cedrus叶子枯 in Winter1. Natural physiological phenomenon: Cedrus is a conifer with a short leaf lifespan, generally 2-3 years. In winter, due to the drop in temperature, the metabolism of Cedrus slows down, some old leaves begin to wither and fall off, which is a natural physiological phenomenon of Cedrus.
2. Climatic factors: The sudden drop in temperature and dry air in winter, combined with the strong wind in the northern regions, cause excessive evaporation of moisture from the Cedrus leaves, leading to yellowing of the leaves.
3. Improper maintenance: Some maintainers do not properly care for Cedrus trees in winter, such as insufficient watering or improper fertilization, leading to poor growth of Cedrus and resulting in yellowing leaves.
Cedrus叶子枯 Maintenance Tips in Winter1. Control watering: Cedrus requires less water in winter, and the watering frequency should be reduced accordingly. Generally, watering once a week is sufficient. When watering, ensure that the water is evenly absorbed into the soil and avoid waterlogging.
2. Reasonable fertilization: Cedrus has a reduced ability to absorb fertilizers in winter, and the amount of fertilization should be reduced. A compound fertilizer with appropriate amounts of nitrogen, phosphorus, and potassium can be used, applied once a month.
3. Enhance cold resistance: To improve the cold resistance of Cedrus, pruning can be carried out in winter to remove sick and weak branches, promoting ventilation and light penetration. Frost inhibitors can be sprayed to enhance the cold resistance of Cedrus.
4. Appropriate shading: The intense solar radiation in winter can damage the leaves of Cedrus. Appropriate shading can be applied using shading nets or bark materials to protect the leaves.
5. Pay attention to the prevention and control of diseases and pests: Winter is the high incidence period of diseases and pests in Cedrus. Timely inspection and control are necessary. Biological pesticides or low-toxic chemical pesticides can be used for prevention and control.
The yellowing of Cedrus leaves in winter is a normal phenomenon, but maintainers need to master certain maintenance skills to reduce the impact of yellowing leaves on the growth of Cedrus. Through reasonable watering, fertilization, pruning, shading, and disease and pest control measures, the winter resilience of Cedrus can be effectively improved, ensuring its healthy growth.
