Whether you want to add some color to the vacant lot on your block, start a garden on the fly or sneak some marijuana plants into the police station landscaping, seed bombs are one of the handiest weapons in the guerrilla gardening arsenal. They are incredibly easy to make and all the necessary materials can be had for cheap.
Red Clay — If you do not have access to natural red clay, Crayola Air Dry clay works well and is available at most craft stores.
Compost — If you don’t make compost or don’t know anybody else with compost, it can be bought at gardening stores.
Seeds — Try to only use seeds native to the region. New York doesn’t need any more invasive species.
1. Mix clay, compost and seeds at a ratio of about 5:2:1 in a large bowl.
2. Add water in small amounts to make the mixture malleable, but be careful not to add so much that it becomes a messy mush.
3. Knead the mixture into a large ball and then flatten it out to cut into separate “bombs.”
4. Shape separate pieces into small balls (golf ball size works well) or grenades if you are feeling especially militant. Allow balls to dry in the sun for at least 24 hours.
5. With a fully loaded arsenal, hurl your bombs wherever your fancy strikes and the land needs liberating
