Can't recommend- shame on Round-up

8 months ago

Three years ago, this product was outstanding. But for the last 2 years, it has only lasted 2 months before weeds come back up. My use and application for all 3 years has been the same. I am super careful to spray all the pebbles on my paths and the block patio and walkways. I can no longer recommend this product as meeting its claims of 365. Best is 2 months.

ConsDidn't work as expected

No, I do not recommend this product.

Great product for DIY landscapers

11 months ago

Works well but make sure you follow directions. Great for thick lawns and start up new sod. Works well in concrete or paver seams in keeping weeds and unwanted grass at bay. Makes sense to block off areas of your lawn without weeds, so that Roundup does not harm healthy grass

Yes, I recommend this product.

Worth the risk

a year ago

Used it all summer or weeds in cracks if the sidewalk. Sometimes a second application was required. I’ll risk lymphoma rather than go a season without it, with My sloppy neighbors.

Excellent killer, doesn't last for a year

a year ago

This roundup kills just about everything in it's path. However, I'm not sure where they're getting this 365 day nonsense. This stuff kills an area for about 60 days. Then you will need to reapply. Since this is $50+ bucks, and the other is $27'ish that lasts about 3 weeks, you really need to take the 365 off of this product as it's misleading. Is it a great weed and grass killer ABSOUTELY. Does it last anywhere near 365 days? ABSOLUTELY NOT. It doesn't even last (keep killing) past 65 days.
