Seed Bomb History

The kids love the big mess they can make with seed bombs and you can enjoy the great conversations you will have about the importance of growing your own food and planting flowers for the bees.  This garden project isn’t new, though!

I confess freely that making seed bombs from clay was NOT my original idea.  Actually, seed bombs have been in use for centuries and they’ve been made from many materials through the years.

Seed bombs regained their popularity in our modern culture through the efforts of the microbiologist and pioneer in “natural farming,” Masanobu Fukuoka.  He believed that you didn’t need to fertilize, use pesticides or even weed in the garden, but that you let nature decide what would grow or not grow.  (That’s a very simplified version of natural farming, by the way.)

Seed bombs were made and used to provide a variety of different seeds in an area.  In urban settings, you may find your garden savvy friends tossing them into abandoned home sites or vacant lots covered in weeds.  (That’s not something I can publicly condone since even abandoned home sites are still private property.)

We’ve used paper to make seed bombs in the past, and that’s an easy method that  has the added benefit of upcycling scratch paper laying around your house.

Stamped Medallion Seed Bombs

Here’s what you’ll need to make these clay stamped seed balls:

  • Natural clay (not the kind you need to bake)
  • Good potting soil or compost or a mix of both
  • Seeds (wildflowers and hardy herbs are a good choice – Echinacea, poppies, goldenrod, yarrow, bee balm are some ideas)
  • Cinnamon, powdered
  • Rubber stamps and ink pads (optional)

How to Assemble Seed Bombs

  1. Take a small chunk of clay, about an inch in diameter. Stamped Medallion Seed Bombs l Great clay craft for kids l Homestead Lady (.com)
  2. Warm and flatten it in your hands so that it looks like a sprawling circle.
  3. Add a teaspoon of potting soil to the center and sprinkle on cinnamon as an antifungal for when the seed is getting wet in the elements and its protective clay has washed away. Chris from Joybilee Farm also suggests using turmeric for the same reason – great idea!
  4. Add a few seeds to the center of the soil.Stamped Medallion Seed Bomb l Seed ball contents l Homestead Lady (.com)

To Finish the Seed Bombs

  1. Close up your seed bomb by folding your clay in half and sealing closed the edges, making it look like a closed taco or a pierogi.  Clay is great because you can just smooth your finger over the edges until they stick together.
  2. Gently push and mold your clay on a flat surface until it’s in the shape of an oval – or circle or square, whatever you like.  The depth isn’t really that important but try to keep it around 1/4 inch and uniform.  This will help ensure that your seeds are exposed to the elements at about the same time.Stamped Medallion Seed Bombs l Clay is fun to use to make these seed balls l Homestead Lady (.com)
  3. Gently press your choice of stamp into the surface of your clay.  Use a rolling motion to keep your image as clear as possible.  Begin by gently pressing one edge of your stamp into your clay and rolling the stamp to the other side, pressing down evenly. 
  4. You can use ink, if you’d like, to give the clay a little color.  If there’s a goof, just smooth it out with your finger slowly, and being again.  If a hole appears in your seed bomb, add another thin layer of clay.
  5. Air dry and then wrap to give as a gift or plant right before a good rain.Stamped Medallion Seed Bombs l Clay kid activity for rainy days l Homestead Lady (.com)

Note: The only secret is in being gentle with the stamps so the picture ends up clear.  If you have artists tools for clay, or want to use a bamboo skewer, you can etch your own designs into the clay.  I do projects like this with five children, ranging in ages from 13 to 3, so I like the simplicity of stamps.  However, my teenager went off to the side and started engraving Egyptian symbols into her clay with a small stick.

 

An Educational Aside

If you’ve ever made your own seed bombs, feel free to let me know if you’re technique is different.  I’d also enjoy knowing what kind of seed you decided to plant – that will vary so much from growing zone to growing zone. 

Aren’t familiar with your “growing zone”?  No worries, check out the course below:
