Don't talk to me about creeping buttercup!

Last year I tried digging it out, but my lawn ended up looking a bit
like a rugby international had just been played on it. This year, I've
dug less out and am trying a chemical approach. I can't remember the
name of the weedkiller off the top of my head but it will be 2,4-D
based as per various website recommendations.
