Overwintering SHB container blueberries in Z5?
I have a Farthing and Sweetcrisp in containers. They grew well this year but I'm concerned about the winter. I was just assuming that I would have to overwinter them in the garage as soon as winter hits in force. The garage temp is around 35-45 during the winter. The reason I'm asking is that I spoke to a southern blueberry farmer I know and they said that these are grown in Michigan for research and that the cold weather won't hurt them. I have a hard time believing that. We sometimes go below freezing for a month at a time, and as low as -20.
