They're June bearing strawberries, which means they make most of their fruit during the month of June. As for how to keep them alive over the winter, it depends on where they're planted. In Chicken Lover's case, her strawberries do fine with no extra attention, likely due to how they're planted (some places give better shelter from wind/freezing temps) and others need a bit of help. In my friend's case, we spread a bit of straw over them for the winter, or dead leaves from the trees. If they would get a decent layer of insulating snow they wouldn't need too much help, but it's a crapshoot here as to how the snow will be.
