Getting rid of grass but not moss in shady wet garden
I recently moved into a house in central Vermont and am trying to convert the large yard into something other than lawn. The southern edge of the yard, under pines, hemlocks, and beech trees, has a lot of moss and ferns (maybe lady ferns?), as well as some grass and buckthorn saplings.
I'd like to get rid of the grass and buckthorn and incorporate some more diversity to the area, with low-growing ground cover and some full-shade perennials.
Is there a way to discourage the grass from growing without destroying the moss?
