Vegetables grow slower in winter due to several reasons, including:
Reduced sunlight: During winter, the days are shorter and there is less sunlight, which is essential for plant growth.
Cold temperatures: Vegetables are sensitive to cold temperatures, and below a certain temperature, they are unable to grow.
Soil structure: Winter weather conditions can cause soil to become compact and harder, which can make it difficult for roots to grow and absorb water and nutrients.
Reduced water availability: Winter weather can also cause soil to become dry and reduce the availability of water for plant growth.
Overall, the combination of reduced sunlight, cold temperatures, and reduced water availability makes it more challenging for vegetables to grow in winter.
