Growing Instructions for Bird Lover's Wildflower Seed Mix:
In late fall or mid-spring, broadcast into a prepared area (not lawn or hard ground; clear and loosen soil first). Do no just walk away from plot and assume nature will work wonders: one or two weedings will be required. But after that, behold: beautiful flowers!
