I just built a small home on an acre and a half in the woods of Vermont. The ground around the home has been disturbed to make way for septic tanks, french drains, water lines, etc. and now about a half an acre is just dirt.

While I plan on creating a small area of lawn for my child to play, I'd prefer for most of this land to fill with wildflowers that naturally grow on the perimeter of the opening: goldenrod, ostrich fern, aster, etc. What's the best way to encourage these plants to grow?
