How to make seed bombs
Whether you are guerilla gardening or gardening with children, these seed bombs made from recycled paper will inspire your imagination. Seed bombs and seed paper can be made into creative gifts, party favors, or an inspiring nature activity for students. While these instructions turn your recycled paper into a 3 D shape using a mold, you can also make seed paper following these steps, and laying out the paper mache on a screen, in the traditional way of making paper.
Save the bees or grow herbs
Focus on wildflowers, herbs, and annuals to feed the bees as part of a bee garden project.ย Use perennial flower seeds to bring beauty and fragrance to your corner of the world.ย Or use culinary herbs like basil, parsley, dill, and oregano to create an herbal seed bomb for gifting. This is a fun project to do with children or with adult friends in a group setting.
This recipe makes approximately 20 seed bombs about 1 to 1 ยฝ inch diameter.ย I used this heart-shaped mold from Ikea.ย Youโll need two molds like this to make this recipe.
If you’re making this in a group setting, plan on 1 mold for each person participating, and four cups of torn paper pieces for each person.
Materials for making seed bombs:
Paper to recycle, enough to make 6 cups of torn paper.ย Avoid glossy paper.
1 tbsp. Kelp powder (optional)
1 tsp. cinnamon (optional)
1 tsp. turmeric (optional)
Water
1 tsp. flower or herb seeds such as:
Bee Flower Seeds
- Alyssum
- Aster
- Bachelor Buttons
- Basil
- Black-eyed Susan
- Columbine
- Cone Flower
- Coreopsis
- Daisy
- Dill
- Fennel
- Oregano
- Parsley
- Poppy
- Snapdragons
- Viola
- Yarrow
Culinary Herbs to include in seed bombs:
- Basil
- Dill
- Fennel
- Oregano
- Parsley
Equipment:
- Food processor or blender
- Bowls or a bin to hold the torn paper and water
- Potato Ricer or press to remove water
- A siliconeย ice cube or chocolate mold
- Sponge, unpaper towels, or paper towels for blotting excess water
Directions for making seed bombs:
Tear the paper into small pieces until you have enough to fill a measuring cup with 6 cups of paper. If you have a paper shredder, that will make quick work of it.
Add the kelp powder, cinnamon, and turmeric to the paper in the bowl.
Cover the shredded paper with water and let the mixture sit in water for 15 minutes. This allows the paper to bring in moisture and will help it to break down even further in the next step.
Drain off the excess water.
In small batches, process theย wet paper with your food processor to make paper mache (about 5 minutes)
If the food processor doesnโt mash all the paper, try adding back a small amount of water. You want the paper to be coarsely mashed. Process until you see fibre strands at the edges of your mache. This will hold the finished seed bomb together as it dries and contracts.
Remove from the food processor andย using a potato ricer, or your hands, press the excess water out of the paper.
Wear gloves if you used turmeric in the recipe or youโll have yellow fingers.
Remove as much water as possible, so that when the pieces are squeezed, no water drips out.
Fill silicone molds halfway with paper mache.
Youโll need to press the paper firmly into the mold to smooth out any gaps. Use the bowl of a spoon or the handle of a muddler to get a smooth, even pressure.
Sprinkle seeds of your choice sparingly over the top of the paper in the molds.ย If you pressed the excess water out of your paper the seeds will not germinate while the paper dries.
Fill silicone molds up to the top with the remaining paper.
Press the final layer firmly in place.ย Sponge any excess water off the top of the paper in the molds to speed drying.
Let the mold sit for 24 hours in a warm place to dry out
The next day, remove the seed paper from the mold and allow it to dry completely.
This may take a few days depending on the time of year and how much humidity you have.ย Donโt put the seed bomb in an oven, dehydrator, or microwave to speed drying as this will kill the seed and stop germination.ย Allow it all to dry naturally.
Once your seed bombs are fully dry and no longer cool to the touch, they are ready for gifting or spreading around.
To Use the Seed Bombs
Plant the entire seed bomb on the bare ground by digging a shallow hole and covering the seed bomb with 1/8th inch of soil.ย Keep moist at all times, while you are waiting for the seeds to germinate.ย The Kelp will feed the seeds and encourage root growth.ย The cinnamon and turmeric are antimicrobial and will inhibit fungal diseases and insect pests, while you are waiting for the seeds to germinate.

Your Turn:
I hope you enjoyed this tutorial.ย Have you made seed bombs?ย What did you use as a medium?
Giamia says
As a soon-to-be guerilla gardener, I’ll make sure making and using these amazing seed bombs.
Thank you so much!
Brett says
How long will these keep unplanted? I am thinking of making some as wedding favours. But since they take time to make I want to start a year in advance of my wedding.
Joybilee Farm says
It depends on the seed variety you plan to use. But I’d recommend doing this no more than 6 months before your date so that the seed remains viable for at least 6 months past your wedding.
Brigitte says
Hi, lovely post. I too would like to know if yours sprouted well. Mine have never sprouted and I have made these over the course of several years, with different seed and either the bomb format or the paper format.
Joybilee Farm says
I didn’t have any trouble with them sprouting. Is your medium too wet?
Tony McCarthy says
Hi Chris. I use a fair bit of spent coffee grounds to make compost. You mentioned Turmeric and cinnamon as an antibacterial medium which is something I am going to try in the coffee mix. The coffee seems to display bacterial die off after a few days?
I am interested to know if you have tried sticky vermicompost as a seed bomb medium?
Thanks for the tips.
Regards
Tony.
Joybilee Farm says
I haven’t but I don’t see why it wouldn’t work well.
Sara says
I would love to know if anyone has gotten these to sprout, I understand that it is just damp not soaked, but again would love a testimonial that these work.

Debbie says
I’m looking to make these for party favors but I see a few sites that say the seeds won’t germinate because getting seeds wet and then drying them out kills them. Have you been able to get seedlings from the seed bombs?
Joybilee Farm says
The mash is just damp. Not soaked. They will germinate.
MQ says
whats the story with the cinnamon, kelp and turmeric. Is this adding any growing benefit to your seed bomb, or just for bling?
MQ says
i actually see here at the end, its being explained. thx for the article. ๐
Joybilee Farm says
Glad you found what you need.
tessa says
What a great idea to add the cinnamon and turmeric! We’re doing some seed bombs this week, so I’ll be sure to include that.
Thanks for including our paper making article. Anything involving this level of mess is very fun to do with kids. ๐
Joybilee Farm says
I can’t wait to read your own posts on this. I bet it will be amazing with your kidlets in the pictures.
Bazrsara says
I used this method and the outcome was awesome.
Many thanks

Tessa,
Did your seed bombs germinate?
