Will Copper Nails Kill Ivy

I have heard that driving a number of copper nails around the trunk of a tree the nails will impale the tree, presumably by some chemical reaction. Anyone had experience of this method, - does it piece of work?
I am not intending to kill off any of my trees, just interested in any data.

Howdy alex.. In a word.. No..!!! No it is a myth.. Co-ordinate to my S in Ls years equally a tree surgeon he has come across the "copper nail" myth many times. Some years ago, when cutting upwardly the torso of a poplar, I he came across a ring of copper nails. Several inches inside the wood, the tree had enclosed them and carried on growing with no ill effects ..
My Local Potency'south arboriculturalist used to find copper nails in protected trees that were in the way of proposed developments and some of them were in a bad fashion, merely the perpetrators could well take been using additional ways such every bit concealed drilling, Glyphosate/Copper Sulphate/Ammonium Sulphamate/Etc., then plugging the hole and that could have been responsible.
Merely that was big trees and I've tapped a small copper nail into the likes of very minor ash/elders growing in bad-mannered places such as the junction between walls and paving that made grubbing up the roots incommunicable, and it worked.

I've used this method to kill ivy, when I couldn't reach to chop or saw it, it kills fairly thick ivy stems. It takes a while, I should imagine information technology wouldn't kill a mature tree.

And then yous could achieve to bang a nail in information technology, simply couldn't cutting information technology off with a hammer and chisel??
Subsequently this I would be suspicious of anyone who owns copper nails.

Too large to chop with a chisel pete, I reckon the stem was 8" diameter or more

Yes copper nails do piece of work on smaller trees/plants.
But if you kill the tree so what? You have a dead tree that is a liability in wind etc, and also if the nails have been grown-over, or are not easily seen, they can cause risk to life & limb when cut the tree with a chainsaw.
If the tree has to go so chop information technology downwards would be my communication

Well, you could drill into the trunk at an bending, and so with a funnel fill the holes with SBK weedkiller, stop upward the holes afterwards with putty or similar.
But agree with Marley, simply cut it downwardly if you dont desire information technology.
