Flame gunning is a sheer waste of time. The roots simply regrow.

Not if you do it properly. The idea is simlpy to singe the top growth ,
you
have to do it more than once certainly, but eventually just as if you kept
cutting it, the root dies too. It is a recognised organic way to treat
weeds
if you don't want to use chemicals.



Do you use it for the perennial weeds growing in the cracks in paths? We
have this problem at school and I'm getting extremely fed up pulling them by
hand and I am totally against using chemicals.. It is impossible to get all
the roots!
