We visited family in Boston quite a few times & have seen these hoop gardens in the backyard next door. I always wonder what they have growing in them. I do know these same people seem to have tons of veggies in the spring & summer. Perhaps they do in the winter too.
Here are their secrets revealed. These low tunnels made from hoops & plastic sheeting are easy-to-make little greenhouses. Make them as short or as long as you want/need.
With an extra cold winter predicted for the US Northeast, it might be a good idea to put these up before the really cold temps come.
