We're on the edge of Zones 3 and 4 up here in northern MN. But we don't fear the frosts like most flat-land gardeners with the raised beds. We still have killer frosts that an nuke a plant to smithers, but average frosts are no biggy. The beds keep enough heat inside them to make it work out ok. Took a look at some of your posts/blogs. We have some things in common it seems. We make wine too, and hard cider from our own apples. Tapped a follow to see what other adventures you are all up to. :-)
