Make Seed Bombs For Earth Day

Earth Day might come once a year, but we can keep the spirit of Earth Day alive all year long. Planting seeds is a wonderful kick-off to spring and summer, and learning how to make seed bombs is a great way to get your planting started. Bonus, you can give these seed bombs as gifts too!

Make these DIY seed bombs with simple materials you can pull straight from the recycling bin or use scraps of colored paper. I always save the bits and pieces of whole sheets.

Here we strategically used Earth Day colors in blue, green, and white. You can use whatever is available making it even more eco-friendly!

What Are Seed Bombs?

Despite the exciting name, seed bombs are simply small balls of shredded paper with seeds added. They are great for planting out large garden areas at one time, or for using in pots. You can also make your seed bombs with clay or flour.

It is best to use seeds that are easy to germinate like flower seeds. You can add wildflower seeds to your seed bombs if you want to grow a wildflower meadow with a variety of plants.

We have chosen some easy flowers for our seed bombs that we will then plant into pots for a colorful spring display.

Seed bombs are best used around the same time you make them because the seeds are now exposed to air, moisture and sunlight. Throw out any seed bombs you don’t get to using.

Get Kids Excited For Growing Plants

Get the kids excited for growing plants with this fun, hands-on activity perfect for talking about flowers, science, and more!

How does a seed grow? If you haven’t started a seed germination jar or tried this eggshell seed growing activity, you must have a go! The seed jar was an awesome to learn about how seeds grow.

It’s fascinating to watch flowers grow and bloom throughout our yard all summer long. We love planting a variety of colors and caring for them throughout the summer months and even into the fall for a few of them last year.

Making flower seeds bombs with kids is an easy way to get started!

How To Make Seed Bombs

STEP 1:  Start by cutting your construction paper into one-inch squares. Place each color separately in a container.

STEP 2:  Once you have cut up all your paper squares and each container is ready, add water. Cover the paper completely and allow to soak for 20 minutes.

STEP 3:  When the 20 minutes is finished (the hardest part is always waiting), take one container and squeeze the excess water out of the paper. Place the paper in a food processor and pulse until the paper becomes pulp!

Also check out how to make recycled paper.

Making Paper Pulp for Seed BombsPin

Place the pulp back into its container. Go ahead and repeat with the next two colors until you have three containers of pulp!

STEP 4:  Divide the packages of seeds between the three containers gently mixing them into the pulp.

STEP 5:  Start by taking a bit of each color from each container and forming it into a ball!

We wanted these to resemble the Earth for Earth Day. If you have chosen other colors that are great too! To make the Earth try not to mix up the colors too much.

TIP: These kinds of Earth Day activities are a wonderful gateway to talk to your kids while hands are busy! Talk about the importance of planting seeds, clean water, clean air, conservation and anything else they are interested in hearing about! Getting a little messy and hands-on with kids is super engaging and creates the perfect atmosphere for learning!

STEP 6:  Place your homemade seed bombs on a parchment lined baking tray. You can go ahead and press a few more seeds into the balls if you think they need a few more. Let your tray dry overnight.

Tips For Planting Your Seed Bombs

Get ready! Once dry, toss your flower seed bombs into your favorite flower pot or garden plot. You will still have to dig a hole first! Water gently and keep moist.

How long will they take to germinate? Expect your flowers to poke through the ground in 5 to 7 days depending on which flowers you chose.

These also make fun gifts to give to friends and family. Decorate a flower pot, add a seed bomb, and you have a sweet gift that’s Earth-friendly!

We hope you have founded a fantastic new activity to celebrate Earth Day that you can turn into a tradition each year with your kids at home or in the classroom!
