we've had goats for just a few years and their "pasture" was lawn before so there's really not any browse... we do provide occasional browse, hay, etc... My question is about trying to improve the pasture. It's becoming full of buttercups and I've read that spreading lime can help change the pH and encourage grass growth (we have sheep too).. should I just do that? or should we try to plant some seed? and if we plant seed do we need to till and then plant? keep animals off? I'm so lost and would appreciate help!
