How To Make Seed Bombs With Air Dry Clay

Make your own homemade wildflower seed bombs with air dry clay and a little bit of dirt. Making seed bombs is a quick and simple craft, and a great way to garden with your kids!


Who else loves seeing the beautiful spring colors as the flowers bloom?! We have this big empty lot near us that’s covered in grass and dandelions, and the yellow flowers are kinda pretty, but I’d love to see some more color in that lot. So I decided to make a bunch of DIY wildflower seed bombs with air dry clay! Making seed bombs is such a quick and easy craft, and the dried seed bombs are perfect for guerrilla gardening and turning ugly empty lots or park strips into beds of gorgeous flowers! Homemade seed bombs also make great guest favors for weddings, showers, etc.; just package them up with some instructions and you’re good to go!

How to make wildflower seed bombs

This project can get a little messy, so go outside to mix everything, or at the very least make sure you’re near a sink so you can clean up when you’re done!

Add the seeds, clay, soil, and water together in a large mixing bowl, then start mixing it all together with your hands.

Keep mixing the dirt/clay mixture with your hands, making sure to break up any chunks of clay or dirt as you go. If it’s too wet, add a little more dirt; if it’s too dry, add a little more water. You want it to end up like cookie dough; not too sticky, but not dry either.

Once your mixture looks like cookie dough, grab small handfuls and roll them into 1″ balls. Set them aside to dry on a cookie sheet lined with parchment paper. Unlike balls of actual cookie dough, these don’t expand or change shape at all as they dry, so you can put them close together if you need to.

The seed bombs might take a day or two to dry, depending on the humidity in your area.

How to use homemade wildflower seed bombs

These homemade flower seed bombs have almost everything they need to start growing. All you need to do is toss the wildflower seed bomb into an empty lot, a park strip, or any other pile of dirt. Just make sure they get tossed into a spot where they will get rained on, and it’ll grow. Be sure to stop by again after about a month (and after it’s rained a few times) and you’ll see gorgeous wildflowers growing where you dropped the homemade seed bomb!

You can also package homemade seed bombs up as wedding favors or party favors. Make a cute little cloth bag for them, print out some simple instructions, and hand them out so everyone can spread joy and wildflowers around their neighborhoods.

The recipe below assumes each DIY seed bomb will have enough seeds to cover about 1-2 square feet. Feel free to drop a couple if you want to cover a large area.

Equipment

  • cookie sheet
  • mixing bowl

Materials

  • 1/2 teaspoon wildflower seeds
  • 1/2 cup air dry clay
  • 1/4 cup garden soil or dirt from your garden
  • 1/4 cup water
  • parchment paper

Instructions
 

How To Make Wildflower Seed Bombs

  • Add seeds, clay, soil, and water to the mixing bowl and mix with your hands.
  • Continue mixing, breaking up clumps of clay and dirt, until the mixture has a consistency similar to cookie dough. If it's too dry, add a little more water. If it's too wet or sticky, add a little more soil.
  • Roll mixture into 1" balls and place on a cookie sheet lined with parchment paper. Let dry overnight or until completely dry (may take up to 2 days depending on humidity.)

How To Use Flower Seed Bombs

  • Toss a dried seed bomb into any patch of dirt or grass, and just wait! The morning dew and eventual rains will "melt" the seed bomb and water the seeds, and then they will start to grow on their own.

Notes

The seed packets pictured in this tutorial contain 2.4 grams of seeds, which is about 1/2 teaspoon of seeds, and each of those packets is meant to plant about 30 square feet.
I’m assuming each homemade seed bomb is about 1 square foot worth of planting power in terms of how far the seeds might be able to spread from a single seed bomb. So this recipes is basically doubling the seeds per square foot that the packaging suggests: 1 packet (2.4g or 1/2 teaspoon) makes about 15 seed bombs, 15 seed bombs will plant about 15 square feet.
Feel free to use more or less; the exact amount of seeds is not really important as long as there are enough seeds per seed bomb that even if some of them don’t germinate, others will have a chance.

    what is best time to put these out after making them, what happens if you wait a frew months before tossing them out

      A few months will be just fine! As long as the seed bombs are kept somewhere cool and dry they should last for a long time. I’d try to get them planted within 6 months to a year, but a few months is fine.

    These are also great because just tossing the seeds about would encourage the birds. This way they stay in place until it does rain, and they sprout. Love this idea.

    I would like to make these for my Granddaughters 1st Birthday Party! We are having a Garden Theme, so these would be perfect. What do you think I should use to put them in to give them out as favors?

    • Jessi Wohlwend says

      There are tons of things you can put in them! I put seed bombs in them so guests could plant a bunch of wildflowers on their park strips, but you can add miniature bubble blowers, small plastic toys, necklaces, or seed packets!

    Toss them on the ground..do you mean they don’t need to buried in the groun?

    • Jessi Wohlwend says

      4 years ago

      Nope, they don’t! They have enough “stuff” surrounding the seed for the seed to start growing; all they need is some water. Once they get wet and the seed germinates, it’s roots will dig down into the ground as the plant grows, so no need to bury them in the first place!
