Don’t let the moniker “seed bomb” throw you off: beloved by guerrilla gardeners everywhere, these little balls made from clay, compost and seeds are the secret weapons to transforming barren and neglected urban corners into colourful spaces of living greenery.
Seed bombing is a technique of introducing vegetation to land by throwing or dropping compressed bundles of soil containing live vegetation (seed balls). Often, seed bombing projects are done with arid or off-limits (for example, privately owned) land.
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 fertilizerThey were tossed over fences onto empty lots in New York City in order to make the neighborhoods look better. It was the start of the guerrilla gardening movement.
