Despite the name, seed bombing is hardly as destructive or explosive as the name would suggest. For guerrilla gardeners, seed bombing — or introducing vegetation to an area of land by throwing or dropping balls of seed-rich soil — is a quick and easy way to beautify your home garden, flowerbed, or window box, or spruce up a neglected alleyway or lot. If you’re looking to take up a new hobby or spend more time outdoors, knowing how to make these palm-sized “seed grenades” is a must for any garden enthusiast. The best part? All you need is a bit time and a few ingredients to turn drabby home gardens and abandoned urban areas into beautiful spaces bursting with color and life.
In honor of Earth Day, why not give back to Mother Earth by learning how to make your very own seed bombs.
Here’s what you’ll need:
- Clay (available at most craft shops)
- Peat-free compost
- Large mixing bowl
- Baking tray
A note about seeds:
Make sure you use seeds of plants and flowers that are native to your area. They’ll grow better and won’t destroy your local ecosystems. If your seed bomb contains different kinds of seeds, be sure they all bloom at the same time of year. When in doubt, ask your local nursery for seed advice.
Once you have all your materials handy, it’s time roll up your sleeves and get to work:
Step 1: Mix It
Add 5 parts compost, 3 parts clay, and 1 part seed in the large mixing bowl. The clay in the mixture protects the seeds from a hard landing, harsh weather, and prey such as rodents and birds.
Step 2: Water It
Carefully and gradually add water until you reach a balanced consistency. The mixture should be moist with just the right amount of clay. Too much clay will dry the seed bombs out. Too much water and the seed bombs will be too gloppy.
Step 3: Roll It
Roll the mixture into one-inch sized balls. As you roll, make sure the seeds stay within the seed bomb.
Step 4: Dry It
Once you’ve rolled out each seed bomb, place them on a baking sheet and lay them in the sun or on a windowsill to air dry for at least three hours.
Step 5: Chuck It!
Once your seed bombs are ready, it’s time for the real magic to happen. Toss the seed bombs around your garden, on top of your shed to create a green roof, or inside planter boxes for an extra touch of color. Or, hop on your bike or go for a stroll and throw these tiny seed grenades in areas that have been neglected — just remember to never throw them on private property. Oh, and aim for dirt! Your little garden should bloom wherever there is soil to be found.
More important, be creative. What makes seed bombs great are their versatility.
Step 6: Have Patience
Remember, seed bombs don’t bloom over night. About three weeks after a bomb is thrown, your seedlings will start to find root and grow into beautiful wildflowers, plants, or herbs.
If making your own seed bombs aren’t your thing, you can still be part of the revolution to better your surroundings by purchasing seed bombs at Beethinking. Aside from experiencing the excitement of seeing your bombs burst to life, you’ll be replenishing the earth and its natural beauty. So go ahead, bombs away!
