Round up would have killed the entire plant.
Since other things have "melted", not really, they are turning soft because of the cold, that is what I think happened here.
I am not sure exactly what minus 6 Celsius is, maybe 23, 24 degrees Fahrenheit, that is way too cold for this plant. If you put my butt in a place like that, I am not going to look to good myself!
It's worse then I thought!! 21 degrees Fahrenheit!!! At that temperature plant cells freeze, the cells burst because of the water that they hold. Then they go soft and then black.
