    I have used Round Up concentrate plus for many years with great results. However, this year I decided to go with the super concentrate, "Bad Idea" . As usual i mixed per instructions, the super concentrate calls for 2 1/2 ounces per gallon i used 3 ounces. I applied the product on a sunny warm calm day while the weeds were in growing mode, you have the best results when applied as mentioned. Almost a week later i expected to see some very dead weeds, nope the weeds were not affected or the least bit wilted. So i re-applied, this time using 6 ounces per gallon, a week later the weeds actually appeared not only healthy but had grown taller. Stay away from this new product use the old concentrate plus at least it works. I wasted $50.00 and 4 hours labor on a weed fertilizer. I called the company and they will refund the cost, but what about my labor spent, oh that's free according to them.

    Comment from ScottsCustomerCare - 11/12/2014

    We are sorry to hear that you did not get the results that you expected when using Roundup Weed & Grass Killer Super Concentrate. Typically, weeds start to wilt in 1 day and take 1-2 weeks to get a complete kill. Using a higher concentration than is recommended does not mean that you will get better results. The product must travel through the plant system to work. The younger the plant and the more plant surface there is to cover the better the results. Also, note that plants with waxy surfaces are more difficult to kill. We want you to be confident in our products, which is why we offer our product guarantee. Our guarantee is for only the product that you purchased and does require proof of purchase. If you have any additional questions or concerns, please use the following link to contact us.

    Round up 50% kills all weeds. It took 2-3 days before I noticed anything, but then it was dead
