Seed bombs originated in the 1930s by a Japanese microbiologist committed to natural farming. They've since been used to beautify large cities by guerrila gardeners that dropped the "bombs" in barren spaces where they grew into a field of flowers. I was gifted some wildflower seeds in the spring, and was trying to find a way to get the kids involved in planting them. This project combines dirt, creating something called a "bomb" and finally an end result that can be thrown. Perfect kids project, ha! These are also a fun gift for a gardener in your life, you can never have too many plants!

A note when selecting wildflowers - be sure to choose a mix that is native to your region. Wildflowers tend to reproduce by spreading their seeds, which means that you could end up with a whole neighborhood of invasive plants if you aren't careful.


  • Air dry clay (we used a 2.5 lb container of Crayola air dry clay)
  • 3/4 cup compost or potting soil
  • 3/4 cup seed mix
  • Water


The Method

Mix the clay and a small amount of water until softened. Knead the compost and seed mixture into the moistened clay until combined.


Shape into small balls (or giant ones as G preferred), and let air dry overnight.


Find a safe spot to drop the bombs and wait for your seeds to grow!
