Why does the grass wither in winter?

1, the temperature is low, so normal photosynthesis cannot be carried out. The grass leaves should be peeled off to avoid consuming too much nutrients.

2. In order to keep the vitality of plants, in winter or even autumn, the grass will wither on its own, so as to reduce the energy consumption and the speed of metabolism.

Not only grass, flowers and trees will protect their roots in this way.
