I'm guessing you don't actually have a 'lawn'? I guess I didn't look and see if you list your location...
Like hell I'm going to post my a Google Map view of my house on ATOT.
To answer your question, the front is desert landscaped and has no lawn. I do need to get some gravel in there, there was gravel there in the past, but I believe it was stolen before I moved into the house. The back yard was landscaped as well, oblong oval grass in the middle with gravel around the outside. Its been unmaintained.
Roundup doesn't do much and leaves massive gaps of live plants.
My plan is thusly.
- Purchase lighter fluid, the kind normally purchased for lighting charcoal grills. Purchase a hose, and spray nozzle with decent range. Connect hose to faucet in back yard, test water supply and range of sprayer.
- Spray some lighter fluid over a small section against the concrete wall furthest from my house and patio. Light with pocket lighter. Observe results. Extend flames with lighter fluid if required.
- Snap photos.
