Beets are a cold weather plant. I usually plant late March once ground is unfrozen from winter. I live in Grand Junction Colorado we have pretty mild winters . I let them grow large there easier to handle since I pickle them usually harvesting after first frost. There sweeter if you wait after first frost. The tops are a different issue they get frosted and wilt harvest tops before a freeze . Beets are done after tops wilt but can remain in ground before ground freezes. I am going to harvest mine after first frost and trim some of the tops for a friend . To answer your question there okay at 32 degrees but must be harvested before ground freezes.
