I need to de-weed a driveway and paths that are completely ravaged by weeds. I am not able to do this repeatedly and so just digging the weeds out does not seem to be a good option especially given a dodgy knee.
I am worried that using a normal weed-killer, salt, acetic acid or a weed-burner will kill or harm various insects, bugs, worms and so forth. Is thee a cruelty free way to achieve this?
