So, my official zone is too cold (4B) for even hardy figs, but I have a patch of microclimate on the south side of my house that I would guess could be as much as a full zone higher than the rest of the yard. I can overwinter plants there that should not overwinter here.
I would love to plant a fig for my husband. He grew up with one in his backyard and misses fresh figs. However, the spot where I think the tree would grow best is just a few feet from the foundation of my house. I understand fig roots can do a lot of damage, so in general the trees should not be planted near a foundation - but is that still true for trees that are on the far northern edge of their range and will be dying back to the ground every winter?
