We live in southern Minnesota and want put some raspberry bushes in the backyard, being new to gardening should we wait until next spring or could they establish themselves well enough during the hot summer months to survive the winter without expert attention?
What’s your source of canes? If they’re free from a neighbor/friend and you can get more later, and the only thing you have to lose is water and effort, then give it a shot. If I were paying for them I would wait for when they are dormant in the fall/early spring.
