Hi Dan,
Yes, I think they're the plaintains you described although looking at the attached text my problem plants in question are small and flat to the ground. I have two shetland ponies on it the moment but will put a few sheep on it at the end of the month as the grass start to improve (the ponies can be prone to laminitis). Should the sheep grazing sort the plantain issue or is intervention requied? I'm wondering if now would be a good time to section off the area and use a herbicide.
Cheers
David (managed to spell my own name this time!)
