The question is - how do you secure them to the tree trunks because I
thought that banging a nail into the tree will kill or hurt it.

thanks


Healthy trees are very difficult to kill, a nail certainly will not,
though there is an urban myth that copper nails will. However nails in
trees are bad news if someone is working on it with a chain saw and hit
the nail. That could well injure the operative, and most certainly ruin
the chain.
