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?
Look into a greenhouse. Pretty sure cheap versions with plastic will do just fine - assuming they can handle some snow on top without breaking
Also consider a MN native berry bush. Pretty sure there are a bunch you haven’t thought about or knew existed.
