For more than 10 years I worked on urban gardening (including allotments, community/collective gardens, guerrilla gardening and street gardening) to establish that (1) even though urban gardens has been seen from some academia as a pimp-your-neighbourhood activity, it actually addresses and affects some of the most striking issues of our time, such as the social and spatial injustice conditions, marginalisation and deprivation; and (2) urban gardening is a first and foremost a socio-political gesture that that is performed via the mobilisation of biological material and the activation of material-semiotic networks in the space of the polis.
