Why should the use of vinegar as a weed killer be considered organic?
It's a chemical just as much as Glyphosate or NPK fertiliser is, just
because you put it on your chips doesn't make it organic.

I understand that vinegar was traditionally made from natural products,
wine amongst them. However, today it is possible to buy vinegar which
is made entirely synthetically. In the case of the former I understand
that provided the vinegar is not made too strongly it actually serves as
nourishment for the microbial life within soil. Whether modern
synthetically-manufactured vinegar does the same, I am not sure.

What is pertinent in my case is that vinegar of either kind sprayed onto
foliage does not reach and kill the roots.
