Hi all

I have joined this as my boy friend and I have a problem. The garden of
our new house had not been touched in aprox 5 years, so we have set
about it with back breaking work and are down to the soil now, but
previously had brambles, nettles and grass shoulder deep in parts. Now
looking at a way to get a new lawn down 9/10 weed killers need the weeds
to work on the roots, but we don't want weeds, esp brambles, sprouting
through our lawn.

In a nutshell we need a root only weed killer that will keep the soil
fertile PLEASE HELP!!

Never heard of such a herbicide and can't imagine how it could
work. If it were me, I'd simply let any new growth from weeds
emerge for a couple weeks, then apply glyphosate. Since you seem to
be from the UK, you don't want to be trying to establish a new lawn
until Sept anyway. That leaves plenty of time to kill weeds the usual
way.
