Double irony is that burning weeds *will* make dioxins.

You don't burn the plants with a weed burner though you just waft the
flame
over them enough to cause a visble change in colour and/or wilt. The heat
damages the cell structure and the top growth dies. Depending on the plant
that may or may not be enough to kill it.

The small gas cannister "walking stick" things are fine for small weeds
between paving or in gravel but not so good for big weeds or large well
vegitated areas.

Glyphosate is considered "safe" though the stronger concentrates have been
removed from retail sale. They are still available from agri merchants
etc.
Cheap generic "Weed killer" you get from a shed will have as much water
(cheap) and as little active ingredient (expensive) in it that they think
they can get away with. Look at the lables...

I have been using roundup and weedol even tried the 24 hr fast acting stuff
but its all useless.

I started off with nettles a couple of feet high across the back and was
trying to get at them early b ut now they are 10ft high and have started to
"march" across the lawn as the get bigger and more widespread.

Nothing has worked. I know putting a bonfire on the ground clears it for a
time ( and then they start again.

I have tried smothering the ground with thick carpet but they grow through.

This isn't a few dandelions in the patio - so what is there that will work?
And the green wellie chemical free brigade can come and hike in my stinging
nettles and see how they like it, if they want to object - I am pro anything
that will do the job.
