Raspberry Heat Tolerance
I live in central NC. I am under the impression that red raspberries prefer a cooler climate than mine, and I'm aware that blackberries do much better here. I'm thinking that purple raspberries would do better in my climate. I could site my berry patch in partial shade, but I'm not sure if that would be the right approach.
Does anyone here have any advice regarding raspberries in Zone 7 (maybe 7.5 really)? Do I have some incorrect assumptions?
