Program Background

Green School poplar logo

UMass Extension’s Green School is a comprehensive course for horticultural professionals who wish to gain an understanding of economically feasible and environmentally responsible plant and land care practices and the relation of those practices to the protection of the environment.

This course is designed for practitioners such as landscapers, lawn care specialists, nursery operators, sports field managers, public and private grounds managers, arborists and others in the green industry. Both experienced professionals as well as those entering the green industries benefit from this course.

Green School students learn about sensible and sustainable methods of plant and land care as well as responsible nutrient and pest management. They learn scientifically sound information that enables them to make better purchasing and management decisions, and to be better stewards of the environment.

The curriculum, which emphasizes a systems-based approach to plant care, is based on current research and focuses on environmental stewardship, Best Management Practices (BMPs) and integrated pest management (IPM). Students develop an understanding of how proper management practices can enhance conservation of precious natural resources such as soil and water.

Green School is taught by University of Massachusetts Amherst Extension Specialists and UMass Stockbridge School of Agriculture faculty. Instruction is done via classroom style lecture and interactive activities, and is supplemented through online resources via an online learning management system.

Green School has been successfully offered to the industry as a certificate short course since the early 1990’s, and more recently for UMass Amherst Stockbridge School of Agriculture academic credit.
