The Art of Seed Bombing : Combine two parts mixed flower seeds with three parts compost; stir in five parts powdered clay, and moisten with water. Form balls one inch in diameter; let dry for 24 to 48 hours (stash in an empty egg carton). Throw everywhere and flowers will grow !!!
My favorite paper seed bomb recipe. Paper seed bombs last longer than compost-bombs and are friendlier gifts to n00bs. I bought a cheap immersion blender at Target that I use just for bombing/misc. crafts. The rest is all newspaper or brownpaper that you have lying around, native seeds, H20, and you.
