[Natures Babe]

Hello Tessa, we had about five weeks of snow last winter and the previous year the hoops covered with environmesh collapsed under the weight of snow and killed off my overwintering broad beans, so last winter I erected a strong metal tent ( upside down V ) over the beans covered again with environmesh. The tent shape allowed the snow to drift down the sides of the mesh leaving a lighter covering of snow which acted as insulation and my beans survived well, to give me a good crop when the weather warmed again. I wonder if this technique might work well for you too?
