Why do roses actually shelter for the winter?

When it comes to shelter, everyone thinks that it is needed to protect against low temperatures. This is how the cause-and-effect relationship works in our understanding. In the case of roses, everything is completely different.

Expert explanation

You will be surprised, but sheltering roses does not work to protect against frost. Only a thick layer of snow can help plants. If the snow layer is about 80 cm, then the temperature difference above and below it can be up to 20 degrees. That is why plants need snowy winters and shelter.

Shelters for roses perform a protective function, but from moisture. It is because of it that in the spring you can find blackening, darkening and rot. Moisture causes infectious burns. So cover your rose beds for the winter to reduce the risk of negative effects of moisture.
