Environmental Horticulture


The Environmental Horticulture program at Lake Washington Institute of Technology provides high quality instruction and hands-on learning experiences in the field of horticulture. Students complete the program ready to compete for jobs in the Seattle area and beyond. This includes working in landscape maintenance, landscape design, greenhouse growing, retail and wholesale nurseries and more. Students will have a broad base of knowledge and practical experiences as they learn what it takes to be an industry leader, use critical thinking skills and understand sustainable horticultural practices.

Students at LWTech can earn an Associate of Applied Science (AAS) degree, a certificate of completion in Environmental Horticulture - Midpoint, a certificate of proficiency in Environmental Horticulture, and a certificate in Growing. Core horticulture classes for either degree can be completed in four quarters. This is a cohort program by design, which allows students to follow the same classmates and instructor together until graduation. The cohort program provides a unique opportunity for students at LWTech to build a tight-knit network of like-minded professional horticulturists. The Environmental Horticulture program meets four days a week, six hours a day on Monday, Tuesday, Thursday and Friday.
