I'll start by asking them what it was they sprayed.
If it was Glyphosphate, I will try contacting Monsanto and
asking their advice on de-toxifying the ground. I know from
past experience grass won't grow again for around a year.

There's some confusion here. The whole point about Roundup/Glyphosate is
that it *doesn't* poison the ground - it's absorbed through the foliage of
plants and poisons them, but not the soil.

That's why, for example, people growing trees commercially can spray round
their trunks with Roundup, and why cereal and oil-seed-rape growers often
spray entire crops with roundup late in the season, without impacting their
ability to drill a new crop a few weeks later.

It's true that if you spray-off a lawn, then weeds come back first, but it's
not because the soil's toxic, just that the weeds spread by a different
mechanism to grass.

Rake it all over, and sow some more grass (with something to fire it up a
bit as well), I would.

Of course, it might not be glyphosate they're using.

Cheers,
