Dear All,
due to lack of time I had to ignore the driveway. Now weeds and grass
have taken root to such an extent that quite a powerful pressurised
washer cannot shift them. Any suggestions that could avoid me
spending days on my hands and knees?

A Karcher. Wicked, will take minutes. Set it to fine jet and apply it at a
distance of nothing from the root. It will drill holes in concrete, let
alone moving the odd weed. The other option is a flamethrower, which I used
on a couple of stubborn ones :-) (actually sycamore trees growing in the
cracks)

They are very cheap from garden centres, just one little bottle of gas and
the job's done.
