Using weedkiller is DIY gardening.

Fallacy
Tested with 10x 4inch copper nails into base of sycamore 5 years ago and it still lives

It's not entirely fallacious. The people who owned this house before us
mounted a tap on a cherry tree using brass screws and that was making
the tree rather poorly. Admittedly, it wasn't dying.


Brass != Copper?

Brass is an alloy of Copper and Zinc.


Yerss.

If anything brass is slightly more reactive than copper so it will do
the same thing.

?? Just because it's got copper in it?!

Brass is an alloy not a mixture...

E.g. Brass screws seem to last extremely un-reactively, esp
outdoors, next to no corrosion or leaching.

Copper wire can be added onto roof ridges etc purposely to leach
to kill mosses etc on the pitches of the roof...
