I followed the directions exactly and it has been three weeks to date. None of the weeds died and are in fact thriving and flowering. Disappointed that I wasted money and time with no results.
Expert response: Thank you for your feedback! This product has Atrazine, which will work on some plants but may require multiple applications on mature or resistant plants. If you would like to share with us what specific plants you are targeting, then we may be able to recommend a more appropriate post-emergent herbicide for your needs.
