I have 2 acres with a 13.2 pony and sheep (other horses on 3 sides). I've always keep my field in good condition but due to really crap year of physical and mental health issues and loads of external stresses/time pressure my poo picking went to put. Pony well cared for otherwise but just the basics. I'm now much better and trying to work out what the hell to do to put my field right. We have harrowed quite a few times when dry enough in that time but the grass on the poo patches is weedy and rough. Any ideas ?
