Seedling growing out of soil.

Watch your seed bomb sprout!

It can be tricky to grow plants from seeds. Why not make some seed bombs to give your seeds the best chance to grow up?

You will need

  • Garden dirt
  • Flour
  • A container
  • Water
  • Vegetable, flower, or fruit seeds
  • Sun-safe gear, including a hat, long sleeves and sunscreen

What to do

  1. Dig up a few handfuls of dirt from your garden and place them in a container.
  2. Flour and dirt in a plastic container.Add roughly the same amount of flour to the dirt.
  3. Mixture of flour and dirt in a plastic container.Add water to the dirt and flour, mixing thoroughly until you get a sticky muddy paste.
  4. Take a bit of the muddy paste and shape it into a little bowl.
  5. Seeds in a handful of mud.Put a few of your seeds in the dirt bowl.
  6. Muddy balls in a plastic tray.Roll the muddy dough into a ball and put aside. Repeat steps 2 to 6 until you’ve used up all the paste.
  7. Dried out mud balls in a plastic tray.If you want to use the seed bombs later, dry them under the sun for a few days. If you want to launch them immediately, throw them into your garden and wait for the seeds to sprout!


What’s happening?

Seed bombs are an ancient invention, that was rediscovered by Japanese farmer Masanobu Fukuoka. In Japanese, they’re known as “nendo dango”, which means “clay dumpling”. These “clay dumplings” have many benefits for gardeners. They contain lots of nutrients to support new plants, and they protect the seeds inside from birds and other critters. Plus, they’re easy to throw which makes spreading them lots of fun!

Your seed bombs will stay hard until they get a good soaking. Then, the dirt and flour holding the seeds will start breaking apart. Water will get to the seeds, helping them sprout, and their growth will help break the ball further. With time, the seed bomb will become part of the dirt and the plant will settle in.

Don’t worry about planting at the perfect time. Just throw your seed bombs around and wait. You can let nature tell the seed when it’s time to wake up and give your garden a lively green explosion!

    Soil is a preferable word to dirt!

      Hi Rod,
      Thanks for your comment!
      I agree that soil is a much nicer word than dirt. For this activity, mineral rich soils are much more effective than organic rich potting mixes – so I picked the word dirt to try and imply that. I’m sorry if it missed the mark for you.
