I love the look of your fig trees against the fence with the great view. When I bought my first fig trees from Joe Morle, I think it was 2011, he told me to bring them in at Thanksgiving and put them out at Easter. I only have potted figs. I have had to shuffle some with leaves in the spring, but in general that rule has worked well. I believe this year we will have the least loss as my husband spent a lot of time putting cardboard along the walls of the shed and I have been able to see how each plant is doing. I agree with FigTrees 2013 that the wind is often more damaging than the cold. I'd love to see more pictures of your trees through the season.
