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?

Neither of which are an issue in a space like this:

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.


I never said anything about killing the roots or seeds. I said:

"Why not make them disappear completely the first time through? I doubt

"Any sooner" refers to the fact that a complete burn and a leaf singe may
both result in the weeds returning but that I doubt that a complete burn
will make them come back "any sooner".

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

Some places can't be mowed, such as the area in the picture above and
around my picnic table.



and, well, it probably looks like crap.

Complete disappearance of weeds as soon as the job is done or days waiting
for the wilted weeds to die off. Which looks more like "crap" to you?



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