Love Gardening? Make Seed Bombs

 In Explore Ecology

20141104_095150When Garden Educator Bianca Pisano made seed bombs with four of her classes at Summerland Elementary School, she was surprised by how much the children loved the process. “It was one of the most popular lessons I’ve taught. The kids really liked the idea of creating little balls of life and bombing flowers into cities.”

Bianca, an educator with the Explore Ecology School Gardens Program, started the class by talking with the children about seeds and plant life cycles. “After the students had a deeper understanding of seeds we talked about why seeds bombs were created.  I explained the history of seed bombs as a tool to be used in guerrilla gardening to green our cities. I had each of them act out how they were going to throw their seed bombs to get their bodies moving and ignite some more passion about the project.”

Bianca and her students made about 80 seed bombs out of organic compost, dry clay, California Native Wildflowers, and water. As part of the lesson, each child got a chance to practice their measuring and math skills to add the various components to a big bowl.  Bianca explains, “After all the ingredients were in the bowl, the real fun began. We all took turns mixing the ingredients and squishing it around with our hands which let us get dirty and felt amazing between our fingers. When we had a seed bomb paste of sorts, I demonstrated how to create the seed bombs and how much of the mixture to use for each.  After that the kids were on their own and loved squishing and rolling the mixture into little balls.”

If you want to make your own seeds bombs, here is Bianca’s Recipe.

Here’s what you need (Makes 8-10 balls):

  • 1/2 oz native wildflower seeds.
  • 3 1/2 oz dry, organic potting soil
  • 1 1/2 oz dry clay (we suggest powdered red pottery clay)
  • Water
  • A mixing bowl
  • A cookie sheet for drying the seed balls
  • wax paper

Here’s what to do:

  1. Line cookie sheet with wax paper.
  2. Mix seeds and potting soil together.
  3. Add dry clay and mix again.
  4. Slowly add water while still mixing the seeds, potting soil, and water into a well-blended paste.
  5. When you are able to form a ball of the blended material without it falling apart, you are ready to stop mixing.
  6. Mold the mixture into small (~1 inch diameter) balls and place cookie sheet or tray with wax paper.
  7. Allow balls to dry in the sun for at least one day.

What to do with them?

  1. All you have to do is throw them at a patch of dirt and watch it explode! Once it rains (or you water them), they have everything they need to grow.
  2. They also make great gifts!
