Could be daisies, but also could be plantain, leaves for plantain are
very coarse and string if you pull them away.

Selective weedkiller would help. if you don't want to use a weed killer
then you will have to dig each plant up. but remember the old lonnie
donnegan song, which siad,'he had such a job to pull them up that he
called them daisy roots'. Daisy roots are tough and long, but I always
foung it therapeutic pulling weeds out of the lawn.
