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?

pH adjustment is used by trees to fend off "vegetable attack". Citrus
trees do this all the time.
