If you have ever wondered how to make seed bombs, you’ve come to the right place. These are so much fun to make. And in case you’re wondering what to do with them, they are a fun surprise to add to your garden and handy for hard to reach places.

Yes, you may have heard of people wandering their neighborhoods or driving down roads and randomly tossing these seed bombs around to add a burst of color to the area BUT I feel compelled to let you know that in some places, this is illegal. Proceed with caution.

How to Make Seed Bombs

Seed bombs make a great gift for gardener friends and are a fun idea for selling at a school bazaar. Here’s how easy they are to make. If your kids like digging around in dirt, get them involved in making these. They’ll love it!

These are also great for a wedding or party favor. We used something similar for my daughter’s wedding and made seed paper to give out as thank you gifts.

Materials Needed:

3 parts potter’s clay powder

5 parts potting soil or compost (no peat added)

1 part seeds -wildflower seeds work best in seed bombs. Choose plants that are native to your region for best results and so as not to harm the local flora and fauna. It’s also advisable to use a seed mixture as this will give you a better success rate.

Some people use air dry clay in place of the clay powder. If you do that, I find that the best ratio is 4 parts clay, 1 part soil or compost, and 1 part seeds.

How to Make Them:

Combine all ingredients. Be sure that they are well mixed for best results. Add in a little water. Don’t add too much or you’ll just make mud. You want to add it gradually until you have a clay-like consistency that can be formed into balls.

Dry in the sun for a minimum of 3-4 hours.

How to Reach Success with Your Seed Bombs:

As mentioned, using wildflowers (which often grow very easily) is one way to ensure that your seed bombs will work. Buying seeds that are native to your area is another way to increase the possibility of success.

The clay not only helps hold the balls together, but they help prevent birds and other animals from eating the seeds before they can even take root. If you’re having a problem with animals eating the seeds, try the air dry clay method. Mix together the seeds and soil/compost and then make sure that it is completely covered with air dry clay to make it less appealing to birds and other animals.

Be sure to wait until the danger of frost has passed in your area. Wait for a spring day when a heavy rain is forecast before tossing your seed bombs. This will increase your chances of success.

Store unused seed bombs (such as those you’re giving as a gift or using for a party) in a dark and most importantly, a dry place.
