Encouraged by my first dose of weed killing (nothing happened, or darn little did) I mixed up another batch from concentrate and soaked the weeds. Now, days later, the orange dead grass for the most part surrounds nice green baby weeds. Looks like a dog with a bladder infection went for a drunken squat all over everything.
You will think I am crazy but I wonder why I couldn't BURN them out next time. A propane torch with a thin multi-thousand degree flame. Just pin point the damn weed and burn it down/up. As long as I am alert to possible fire spreading, shouldn't that do it once and for all?
