How can I keep grass out of my flower beds?
Every year I have to spend at least two days pulling grass out of my flower beds. Last year after pulling every single blade of grass out of the area I mulched about 2 inches hoping this would take care of the problem. I then put pine needles over the entire bed to put my garden to sleep for the winter. (I live in the snow covered for 6 months Sierra Nevada Mountains.) When I raked the pine needles off this spring the dreaded grass is back!
