We have soft rush every year and a rare crop of thistles this year, despite having cut them before seeding last year.
I'm thinking weed wiper. We sprayed the rushes a couple of years ago with the knapsack sprayer, but even with care, the clover in the sward around the clumps of thistles was pretty devastated.
Anyone got experience of using a weed wiper that they can share, good or bad?
