Do you just want to kill the dandelions or nuke all vegetation?

For the most part that would be the aim.

If it's to nuke everything, then sodium chlorate.

The areas to be de-weeded are borders with a few large hydrangers(sp) but on
the whole it would be for around 80% plant destruction. Casualties of war would
be minimal and certainly not really missed.

How long would a sodium chlorated soil remain hostile to re-planting?

If you want to be selective, then a glyphosate weedkiller is the usual
choice.

Not really fussed about saving anything as there's nothing that really to be saved.
