Guerilla gardening made easy!

Whether you live in the suburbs or the city, seed bombs can be a great way to promote beautification–and making them is a fun craft for both children and adults! But what are seed bombs? They’re not violent; seed bombs are balls of clay, compost and seeds that can be thrown anywhere that there’s grass or soil, and don’t need any work after being thrown.

If you have unused public lots in your area, or if you want to toss some wild flowers into a bare patch of your own garden, consider making some seed bombs to spread some beauty! We’ve got the details on how to make some below.

Note: Respect private property! While seed bombs let you easily grow beautiful flowers wherever you like, respect others’ privacy and property. A vacant lot can be a nice place to throw some, but don’t throw them into a neighbor’s yard.

What You’ll Need

  • Seeds
  • Potter’s clay powder
  • Compost
  • A mixing bowl
  • A baking sheet
  • Water

What seeds are best for a seed bomb? You’ll want to mix together seeds that would all be sown at the same time of year and work for your climate. Great plants for sunny areas are meadow flowers, while woodland flowers lie foxgloves work best in the shade. Think strategically about your environment; pairing the best flowers for a certain geographic place is a great way for children to learn about where they live!

Making the Seed Bombs

Making seed bombs is easy!

  1. Take 5 parts clay, 1 part seeds and 1 part compost. You can gauge the measurements depending on how big your seed bombs will be, but keep the 5:1:1 ratio.
  2. Mix these ingredients together in a bowl. Add a little bit of water at a time, keeping a clay-like texture (don’t let it get too watery).
  3. Take your mixture and form it into little balls. Place them on your baking sheet.
  4. Set your sheet out in the sun to dry. Voila!

Now’s the fun part: brighten up some part of town–or your yard!–by throwing some seed bombs!
