I feel like a loser admitting this but here goes: I haven't been mulching my garden. Not much, anyway. I want this year to be different, though, and am hoping for suggestions that don't cost too much. I don't have access to pine needles, grass clippings or some of the other materials listed in the gardening books (salt marsh hay?), but I do have newspaper. Can I use it all as mulch? What about the dyes? Are the pages with colored pictures a no-no in the garden?
