It is well established that urban community gardens (UCGs) can either challenge or reinforce neoliberal urbanism. This duality is especially evident among UCGs that sell garden harvests for income generation. In this article I therefore examine UCGs in low‐income areas of Cape Town, South Africa, to understand how they might sell their harvests while countering the neoliberal food system in cities of the global South. I draw on qualitative fieldwork, including observations and semi‐structured interviews with UCG representatives and civil society actors. Most harvests are currently sold to high‐end venues through intermediary actors in civil society organizations (CSOs) and non‐governmental organizations (NGOs). However, this approach disregards the local community's socioeconomic conditions and undermines community gardens’ nutritional objectives. Yet, under specific scenarios, the sale of garden harvests could mitigate the persistent food injustice in Cape Town's low‐income areas. In this article I introduce a model for harvest sales that advances sustainable urban agriculture and fosters food justice in neoliberal cities in the global South.
