It may not lead to a picture-perfect backyard, but leaving the dried heads of your flowers intact in the fall through the winter can do a lot of good. As they poke through the wintery white snow later this year, the seed heads provide needed nutrients and sustenance to birds. They land on the dead flowers and peck at the seed heads. You can also collect dried flowers with seed heads and bundle them into a "bouquet" of sorts. In the winter, hang them from a tree so birds can feed from your buffet.
