Commercial Horticulture

Commercial horticulture is the science, art, and business of cultivating ornamental plants. This includes arboriculture (the care of trees), 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 run-off. Responsible production practices, both in the greenhouse and in the field ensure that growers protect those same resources.

The commercial horticulture program links green-industry professionals with Cornell University faculty and regional specialists. Our educators bring you up to date research-based information and offer programs where professionals can earn continuing education credits. We'll help you navigate your way to professional certification programs like the NYS DEC pesticide certification program or the International Society of Arboriculture (ISA) certification.
