Roundup Users? What gives?

[cwbow]

Add vinegar to your water to lower the Ph. Most Roundup products has changed the % of active ingredient. So it's not as strong. I have always used 41% gly 2oz per gal and add dawn soap and vinegar. Maybe 8oz to 25gals mix.

+1 on the vinegar addition to reduce your spray solution's pH.

Give it time. Gly can take 10+ days to show full effect. Drought conditions can reduce effectiveness as well.

Make sure that your roundup has surfactant, Some of the stuff like "Pro" "AQUATIC" 'CUSTOM" do not have surfactant and you have to add it.

I guess I’m old fashioned since I still pull weeds by hand. The yard ends up looking better quicker, and you aren’t spraying stuff that is banned in multiple countries because it causes cancer.
