What to do with nails in a mature tree
We have a 40ft Plane tree in our garden, that we inherited when we moved in a few months ago.
A previous owner has hammered nails into the main trunk, perhaps about 20 of them, presumably for lacing Christmas lights to.
I hate to see this and would like to remove them, but don't know if I should. Will taking them out damage the tree or leave it vulnerable to infections?
The tree is huge and seems healthy enough, but the sight of rusty nails in the trunk is not nice.
