Blowtorch...works well so I hear.
I use antifreeze, keeps the grass extra green.
Keeps the dogs from your lawn?
I was out front on my hands & knees pulling weeds earlier in the season.
LOL Gary, I remember you telling me about your Mom working in the garden. All one could see for hours was her derriere.
I use vinegar, salt and dish soap on walkways, driveway etc. Kills everything, don't use on lawn.
