I never thought vinegar was a herbicide, for it is just distilled apple
cider and if it comes from apples then it is good to put on plants. What
gives here? Is it the higher acidity and can it kill a tree?

Question arose as to whether paint-thinner or mineral spirits is a
herbicide and whether pouring it on plants would kill them?

Anyone have experience with these substances poured onto plants and
trees?
