After I cut the 'grass' last week I Weedoled it, but the unwanted flowers have re-appeared. I'll try cutting and Weedol again tomorrow – if it doesn't rain.
It's probably apparent that I'm definitely not a gardener.
Try and leave at least three full days between Weedolling and mowing or vice versa, and Weedol when the grass is not bone dry, but at least 12 hours before it's likely to rain again. It's never straightforward… 
And I don't think Weedol is quite as good as it was when it was Verdone, but it definitely works as there is a clear straight line between weeds / no weeds on a patch of shared lawn where the neighbour doesn't bother.
And +1 for generally leaving the grass a bit longer, at least two inches. And homemade weedkiller can be made with vinegar, magnesium sulphate (although I have heard table salt also works) and a squirt of detergent. Seems to work best on dandelions and fleshy-leaved ones, although if you persist you can kill more or less anything.
