Urban gardening består af haveprojekter i alle tænkelige former i storbyer. Tankegangen er at udnytte den plads, man har og dyrke sine grøntsager selv.

Container gardening makes use of a variety of containers - buckets, old tires, raised beds, windowboxes, kiddie pools, barrels, shoes, and watering cans - for growing all manner of plants for food or beauty.

Urban gardening is the process of growing plants of all types and varieties in an urban environment.
