Using weedkiller is DIY gardening.

Just dropped 25 litres of the stuff on the roots of a tree in a

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. ISTR copper inhibits some enzymes in trees that prevent
various fungal rots from gaining a hold. The same applies to tree stumps
that you want to be rid of without digging them out. Extra nitrogen also
speeds up the decomposition and you can still buy rootout under another
name as a compost accelerator. Still pretty slow for a big stump.
