I have read that a high-concentration vinegar directly onto the soil could last longer than a month but note that many organic diluted vinegar solutions are sprayed on the plant leaves. Small amounts/drops that fall while spraying may last just a few days. There are sometimes plants/weeds that may require additional counter measures to fully remove.
