We've had a problem for years with weeds in our garden. A couple of
times an allegedly professional gardener has put down weedkiller,
which has not been effective.

Here are some jpgs of the weeds as they are now.

I've previously tried Round UP which has killed everything, grass and
weeds, yet the weeds still re-emerge a few weeks later.

I phoned today to www.lovethegarden.com who told me I should try
weedol, apparently this clears out the weeds but does not harm the
grass lawn.

I think the one I need is "Weedol Gun! Lawn Weedkiller 1L"

Advice, please? Is weedol the "magic bullet", is roundup definitely
not advised, are there other products which could suit?
