treegal you will love this thread! Does anyone have any real experience in torching large lawns in lieu of chemically killing them. This makes organic sense as it would kill weed seeds and Bermuda. Is there a tool that would heat up the soil 3 to 6 inches deep so all biology could be destroyed and then you could start over again with compost tea apps and seeding?? Seems to me this would be a great topic and someone needs to make a tool that could torch it deep - deep - deep. The new Fire organic approach!
