Plants in potting soil


Horticulture is the science, art, and business of cultivating ornamental plants. This includes home gardening, arboriculture interior-scaping, landscape and turf grass installation and maintenance, and includes the production of related plant material in nurseries, fields, and greenhouses. Well-designed, healthy landscapes that are carefully maintained conserve soil, protect water quality and prevent nutrient and pesticide run-off. Responsible production practices, both in the greenhouse and in the field ensure that growers protect those same resources.

Cornell Cooperative Extension's Horticulture Program supports the industry with research-based information from Cornell University, combined with local experience and feedback from area businesses. The program offers a range of ways to provide information, and serve your horticulture needs.
