Witold Szwedkowski, poet and Urban Guerrilla Gardening activist, talks about backyard policy, the spade as a tool of rebellion, and the subversive potential of the pumpkin.

Let’s start with a mindful walk. Think about what you see – how many trees do you pass, what are they, do you know them? The guerrilla needs to survey their area of operation. They must estimate the strength of the enemy – the enemy being the excessive use of concrete. They must sound out the weak points and attack there, firing off seedlings, plunging in a shovel. The guerrilla does not lash out at officials, drivers, or those who are disgruntled at the sight of falling leaves. The guerrilla is against the overuse of concrete – vast stretches of granite, oceans of asphalt and rivers of bitumen. These are the things that leave cities lacking in greenery. And we fight lack of greenery guerrilla-style.
