Got some weeds which grow between the large-ish pebbles/rocks strewn around the house foundation. Glyphosate is out of the question. The good, minimally toxic weed killer that used to be sold here (Unkraut-Ex, sodium chlorate) was outlawed because naughty people were using it for things that go boom. My wife said she heard one can use soda and I have lots of blasting soda. Anyone ever tried that? As I'm writing this, just remebered I still have these butane weed torches, maybe I'll give that a try if the chemical route doesn't pan out.
