What has your experience been using 10-20% vinegar for weeds and where can i buy it (other than online)??
Ingham County Michigan
I have not used vinegar for weed control so I can only share with you what I know from research. As the article below states, most of the acetic acid (vinegar) products available for weed control are not systemic which means the impact is burning the leaves on contact. To be most effective, weeds must be small and applications repeated since roots are not killed.
I can not recommend any local sources for purchasing vinegar products but suggest that if you do not want to purchase them online, that you should contact your local nurseries to inquire what products they have available.
Hope that helps.
