I've got yellow plants in the driveway and pea gravel dog yards that I sprayed 2-3 weeks ago and new green ones springing up around them. It sure would be nice to find a better way that would look nice for a while. I guess if your results are quick with the torch, then it's no big hassle to torch the plants every couple weeks.
I was just passing on what someone told me. What's that one poster say..... your mileage may vary [img]/forums/images/icons/grin.gif[/img]
