Seed Bombs

Seed bombs, seed ball or grenade, is a small ball made of clay, compost, and seeds. The ingredients are rolled or moulded into a compact sphere, designed to be thrown or scattered onto bare soil or areas needing vegetation.  

When the seed bomb meets moisture from rain or watering, the clay coating softens, allowing the seeds inside to germinate and grow. Seed bombs are often used in guerrilla gardening, reforestation, or restoring native plant species in degraded or neglected areas.
