In just a couple of days they're gone.
I went to a farm & ranch store and purchased a quart of " farm grade " concentrated Roundup ( maybe 30 - 35 years ago ) . Mixed some up & used it on a fence line . Worked fell .
In the last year , I have purchased pre mix Roundup in the gallon spray jug , twice . Barely worked at all ! :-( Last I bought of that .
Figure it is so dilute as to be almost useless .
