Works Great

This stuff works great! It killed all my weeds and they stayed dead, not like the regular round up that allows you to plant new things the very next day. That one lets the weeds come back right away, too. With this one they're supposed to stay gone for a year. It's only been two weeks since I used it, but so far so good. Let's hope I'm not having to use it again until next year.

Works great!

New formula safer %26 kills weeds %26 grass very fast. Have had no weed regrowth for six months, except for spots I may have missed. Much better on my large crushed shell driveway than trying to pull all the weeds %26 bringing up dirt into the shells. Be careful using this near the plants you want to keep. It will likely kill them.

Impressed with how well it works on tall weeds

[This review was collected as part of a promotion.] We used Roundup 365 to tackle tall, stubborn weeds along our fence line, and it worked amazingly well. Within a day or two, the weeds started to die off, and the area stayed clean for weeks. It's strong and effective — exactly what a busy mom like me needs to keep the yard looking tidy without spending hours weeding. Just a heads-up: make sure to use it carefully. I always apply it early in the morning when the kids are inside and avoid windy days to prevent drift. Follow the instructions closely, wear gloves, and keep it out of reach of children. Overall, I'm really happy with the results. It saves time and does what it promises!
