We have a new lawn, but the pre-treatment failed to kill all of

Is there any lawn weedkiller that is worth bothering with? All
of the other weeds, I either don't mind or can be removed by hand.

Teasing each patch out and using glyphosate is INCREDIBLY tedious,
as well as likely to kill patches of grass (whatever care I take).

You would probably find one of the hormone based weedkillers for
lawns would work but what you then do with a years worth of mowings I m
not sure (but I do know they cause al sorts of problems on the flower
beds!)

Thanks for the warning. That is an absolute no-no. I am not prepared
to fool around with multiple series of compost heaps, even if Herself
could remember which one to use!

One of the broadleaf weed specific ones applied only to the offending
areas will keep the total dose low. And much less collateral damage than
using glyphosate - grass is exquisitely sensitive to it.

You can get them in wax pencil or felt tip/shoe shine style devices.

If it won't degrade in a compost heap in a year, I don't want anything
to do with it.

There are less persistant broadleaf specific weedkillers than
aminopyralid. Using it as a spot weeder might be OK too.

I actually rather like a bit of field bindweed, but it won't really grow
in my heavy clay soil! Hedge bindweed grows very well though!
