When determining whether landscaping is sustainable, we should consider environmental, financial, and human factors. Environmental factors include the capacity of the landscape to damage or heal the system in which it is placed, the environmental effects of the cultural techniques and products used to install and maintain the landscape, and the ability of that landscape to endure without environmentally damaging inputs. Financial factors include the cost of the landscape compared to the economic return in terms of increased property values, the ability to attract and hold industry in the neighborhood, and user fees paid by people attracted to an area by the landscaping. Human factors include the effects on the landscape on mood, employee retention, and health and activity of the individuals who interact with the environment.
