Method 1 Take off your "leaves"

What we often see in winter is that bare plants stand there because of the changes in their bodies caused by the decrease of temperature, which leads to the beginning of leaf loss. When the weather is getting colder and the time of day is shortened, it begins to transfer the nutrients in the leaves to the branches, prompting the leaves to wither and the plants to enter the dormancy period. After entering winter, plants "take out" the nutrients previously stored and decompose these nutrients under the action of enzymes in order to increase the concentration of plant cell fluid, so that they will not be easily frozen

Method 2 Regulate body moisture

Physiological changes are taking place all the time in plants, just like us humans. In winter, plants will reduce energy consumption and enhance cold resistance. Take conifer for example, it can survive at minus 40 degrees, which shows its strong viability. In winter, we find that many outdoor plants will wither, but don't mistake them for dead. This is their way to protect themselves from frostbite in winter. The withering of plants is the performance of reducing water absorption and reducing the content of water in the body

Method 3 Other ways

1. The way pine and cypress spend the winter looks very advanced. Their leaf structure is relatively unique. In order to resist the cold in winter, they mainly achieve their goal by avoiding the emission of water. The epidermal cell wall of the plant leaves is very thick. When it is cold, the cells in the lower skin close, and the root activity decreases, reducing the water content in the body

2. Some plants have their own tips for saving heat. Most one-year-old plants hide their energy in seeds, which continue to reproduce after propagation. For perennial plants, they will store nutrients in their roots before winter, so as to accumulate strength for growth in the coming year

3. In addition, some plants do not hide these necessary nutrients in seeds or roots, but reduce free water to resist the severe cold, such as wheat and rape in winter. Their bodies store a large amount of nutrients
