Hi my son as a new garden and is having trouble with weeds and couch
grass.
We have tried all sorts of weed killers and even tried sodium
chlorate, the
weeds still come through.Thinking about some black plastic and then
covering
it with an old carpet he has to get rid of, is this the correct way
round or
should it be carpet and then black plastic??
Thanks for any help

You do not say if the weeds and couch grass are growing amongst shrubs
or border plants or simply in an area where they can all be dug up and
eradicated by thorough digging. However, the use of weed killers by you
does indicate that the latter is in order. If that is the case dig up
the offending weeds methodically and remove all of their roots. Weed
killers tend to kill the existing weeds but seeds which are dormant at
the time of the application will germinate and grow unless you use
PathClear which kills vertually everything and prevents any growth for
about twelve months or so.
