pasture management: briars
It doesn't seem to be any harder to scythe briars in freezing weather, and when the sun's out we just have to be out with it.
This pasture has been in stockpile since mid-July, maybe, and the skeletons of Queen Anne's lace and chickory, while they look weedy, serve to hold the snow off the grass lower down, and serve as a windbreak as well. The briars make good shelter for rabbits and birds, but take up too much space, so one ongoing task is keeping them mowed.
