How to Make a Seed Bomb | DIY Tutorials

Want to make the world a more beautiful place — one flower at a time? Learn how to make a seed bomb and become a guerrilla gardener! 

If you have an urge to garden but no land or space of your own, consider becoming a guerrilla gardener. (Don't worry, we're not going to war!) Guerrilla gardening involves finding a patch of neglected, drab public land and making it beautiful with flowers, vegetables and fruits. How can this be done? Simply follow instructions, make your own seed bombs and drop them in spaces in need of TLC. They can be thrown out of the car or chucked from the sidewalk.

Be it to improve surroundings, brighten your morning routine going to work or make a statement about food sustainability, guerrilla gardening is all about public service. Because it's about improving your surroundings, the ultimate goal is to pleases the entire community without angering any groups or individuals or causing problems for them. Make seed bombs, not war!

How to Make a Seed Bomb

Before seed bombing, assess a site for sunniness and choose your seeds accordingly. They do not need to be sun-loving annuals: foxgloves would suit a shadier site. Cosmos (above), a classic annual, are a perfect candidate for guerrilla gardening.

Best flowers for seed bombs:

For sunny areas, the best flowers are annual meadow flowers, including poppies, cornflower, marigold, Californian poppies, cosmos; hollyhocks, nigella, verbena bonariensis and viper’s bugloss.

For shady areas, use a woodland seed mix: foxgloves, tobacco plant, honesty.

What you'll need:

  • Flower seed
  • Potter’s clay powder, from any craft shop
  • Peat-free compost
  • Water
  • A bowl
  • A baking tray


Mix the seed, clay and compost together in a bowl with a ratio of three handfuls of clay, five handfuls of compost and one handful of seed.

Next carefully add water, slowly and gradually. (You don’t want it to be too gloopy.) Mix it all together until you get a consistency that you can form into truffle-sized balls.

Lay them out to bake dry on a sunny windowsill for at least three hours.

One they're dry, pack them up and start making the world a better, bright place — one flower at a time.
