WITH reference to the excellent letter on ragwort in the Letters (September 19), may I add a further point.
Why is ragwort allowed to flourish on some motorway banks and roundabouts, especially up-country? The attitude seems to be 'animals cannot eat it there', but surely the authorities realise that plants have to reproduce, usually by seed, and that this seed is carried by various means away from the parent plant.
Allowing it to grow unchecked, even where it is safely out of the way of cropping animals, is simply allowing it to increase, not necessarily where it cannot be cropped.
