Re Mare's Tail - I had lots of this growing - here's how I got rid of it:
Dig up as much as you can and any remaining that are not in close proximity to plants you want to keep - put 35ml to 5l of Weedol RootKill Plus.
Then - plant snowball turnips - the turnips excrete into the soil a suppressor for the mare's tail.
This year I've had a few mare's tail heads poke thorugh and that's it - more turnips at the ready!!!
