Guerrilla gardening
Guerrilla gardening is the act of gardening – raising food, plants, or flowers – on land that gardeners do not have the legal right to cultivate, such as abandoned sites, neglected public spaces, or private property. It encompasses a diverse range of people and motivations, ranging from gardeners who garden beyond their legal boundaries in defiance of state or local property laws, to gardeners with a deliberate political purpose, who seek to initiate change by using guerrilla gardening methods as a form of protest or direct action.
