Seed bombing is a technique of introducing vegetation to land by throwing or dropping compressed bundles of soil containing live vegetation. Often, seed bombing projects are done with local fields and rooftops.

The term “seed grenade” was first used by Liz Christy in 1973 when she started the “Green Guerrillas”. The first seed grenades were made from balloons filled with tomato seeds, and fertilizer. They were tossed over fences onto empty lots in New York City in order to make the neighborhoods look better – this was the start of the “guerrilla gardening” movement.

Create resiliency in local empty fields and rooftops in your area!

Here is a recipe for “seed bombs” used in guerilla gardening.

  1. Gather clay, starting mix and some seeds such as beans, sunflowers, cosmos, calendula, nasturtiums or native wildflowers.
  2. Mix all together, add water, form into balls.
  3. Find a place that is calling for flowers – an empty lot or bare spot needing beauty—toss them in and pray for blooms!
