Roundup (glyphosate) tip:  Always use soft water so you don’t have to add ammonium sulphate.  If you are spraying a generic version, add one ounce of Alligare 90 or some other surfactant to 4 gallons of spray.  If the Roundup label says 2 oz/gallon, add exactly that.  Don’t mix it “hot”. Just be patient.  Give it two weeks to work for great results and a full kill.
