Horticultural therapy students from Virginia Tech University participated in Service-Learning experiences of varying time-lengths at Wilson Avenue Alternative School, the Salem Veterans Hospital, the Virginia Tech Adult Day Services program, Roanoke Hospital Children's Ward, and Warm Hearth Assisted Living Center as part of Hort 3264 Horticultural Therapy and Hort 4984 Activities in Horticultural Therapy. Pre-test/post-test surveys were administered, and written assessments consisting of journals were analyzed to determine the factors most beneficial from these service-learning experiences and modifications that should be made to enhance their effectiveness.
