Well, this year I haven't got so many nor such big sheep and so the ghyll hasn't really been grazed.
For the first time there have been primroses, bluebells, foxgloves, orchids, bugle, yarrow, bedstraw, tormentil, ladies smock and that's just the pretty ones I notice.
So maybe you need to do less, not more? Or a once-a-year-after-seeding mow? I'm going to put my little flock into the ghyll after seeding, so the thistles, seaves and docken don't take over.
