I've just strimmed down some waste ground/overgrown edges for the owner
of some local lock-ups garages, then I went over it with sodium chlorate
weedkiller, to stop any new growth.
He has paid me to do it [1], and I said I'd be back in 2 or 3 weeks to
strim down any new growth, and re-apply some weedkiller to those spots.

How long should i leave it to check for new growth - is 3 weeks enough?
And, probably the same answer, when should I go back and re-apply?

Thanks
Alan.

[1] I now realise why he agreed so quickly for me to do it for £55 inc.
weedkiller - I've spent 3 hours there already, need 1 more hour to clean
up, as well as spending £12 on 3kg of Sod. Chlorate.

I use it on our paved, hardstanding areas where there is no possibility
of damaging run off or leaching, each year and it usually totally
effective for at least 3 months following a single application, however,
there is not much in the way of really difficult weeds (bramble,
bindweed, horsetail etc) now left to deal with.

Ohhh Horsetail! That is endemic at teh front of our properties [a
terrace] it gets all amongst thh garden area and I keep pulling up what
I can, but is there a better way to deal with it that won't kill
everything else in site?? That includes a camomile path between teh
beds.
