Was wondering if boysenberry would grow ok in southern wisconsin zone five. I know they one boysenberry was zone 6. Or is there a certain veriaty that would do better in our zone. Thanks for your time.
Green County Wisconsin
There are varieties, such as the Thornless boysenberry, that are claimed to be hardy for Zone 4. I would recommend planting in a sheltered area. Here in Michigan the last 2 winters (-10F and colder) have killed blackberries to the snowline. Laying the shoots down in the winter using a swing trellis and covering during the winter has been successful here in Michigan.
