The ground is still solid frozen but the sun was able to break through the fog in the evening. So I run out and searched for stuff that I could do. And surprisingly I found something. I have cut down the virginia creeper at all walls to about my hight. I have to do this every winter. Otherwise it would just climb on to the house roof in now time.
According to the weather forecast this night we will get -5°C. But next week does look promising.
