There’s an episode of To the Best of Our Knowledge (a program I recommend) on “Radical Gardening.” It’s hard to imagine any kind of gardening as being radical.
One of the segments was about Richard Reynolds and the “guerrilla gardening” movement which I wrote about here years ago. He talks about his adventures as a guerrilla gardener – someone who tends and plants on someone else’s land. It’s illegal, and yet, I don’t think most people would object to it in the vast majority of cases. It’s the abandoned lot that gets cleaned up and filled with flowers. It’s the ugly roadside that gets covered with native wildflowers. Reynolds is the author of On Guerrilla Gardening: A Handbook for Gardening Without Boundaries.
May first is celebrated by guerilla gardeners as International Sunflower Guerrilla Gardening Day dedicated to sowing sunflowers in your neighborhood.
I like all the suggestions and plans people have posted on their website about creating “seed bombs.” Those are good bombs made of seeds, soil, fertilizer, water and such which you can hurl over that chain link fence into that ugly abandoned lot.
Another guest on that episode is James William Gibson who wrote A Reenchanted World: The Quest for a New Kinship with Nature which examines the ways that people are looking to reconnect with the natural world. That includes the desire to protect rather than exploit it.
If you associate guerrilla and bombs with war and terrorism, then guerrilla gardening and seed bombs are excellent alternatives. If you associate enchantment with wizards and magic, then a re-enchantment with the natural world is also a friendly approach.
