He left his entire estate to New Mexico State University, including $89,000 toward the construction of a dormitory on campus for Hispanic students, and to provide scholarships to these students. The resulting dormitory, Fabián García Memorial Hall, was dedicated on October 17, 1949. In explaining why he left his estate to the University, he said, "I want to help poor boys, for I know their hardship." The Fabian Garcia Science Center at New Mexico State University is named after Garcia, as are the University's Center for International Programs, Garcia Hall, and the building containing their Center for International Programs. In 2005, he was inducted into the American Society for Horticultural Science Hall of Fame. In 2019, he became the first Hispanic and the first New Mexican to be inducted into the National Agricultural Center and Hall of Fame.
