OK, that make sense as far as killing the weed (sometimes only temporarily) but
none of the articles say anything about *why* you don't want to burn them to a
crisp. Other than wasting a little propane, and assuming there is nothing else
nearby that the extended heat might bother, why not make them disappear
completely the first time through? I doubt they'll come back any sooner and
things look better immediately.

(Guess who just scorch-earthed the area around his picnic table?)

maybe because starting a ground fire or
sterilizing the area isn't the objective?

to heat the soil to a temperature which
would guarantee all weed seeds and roots are
killed would take quite a large amount of
energy.

most weeds if you get them soon enough
cannot recover from being cut off.

and, well, it probably looks like crap.

i wonder how many people have started
unwanted fires using the weed scorch method...
