Expert response: Thank you for your comments! We are sorry that you did not get the desired results from using the Speedzone. Keep in mind that more mature plants or late-summer or fall weeds may require multiple applications of post-emergent herbicides. If you would like to tell us more about what specific weeds you are targeting, then we would be happy to troubleshoot with you. We appreciate your feedback and your business!
