Every article I've read about Flame Weeding says that the "trick" or "technique"

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?)

This is strictly a guess. Maybe the idea is to keep some shade on
the ground. That might keep new growth from starting. It works in
regular corn/soybean/wheat fields.

There's lots of shade where I burnt most of the weeks with the torch.
The reason that there is wood mulch around the picnic table is that
the area barely gets any sun. Large maples trees and the house block
almost all sun.
