The family was not released until October 1945. The botanist David Fairchild was instrumental in helping the family move to Miami-Dade County, Florida.^[3]

Ochse became in 1946 a professor of applied tropical botany at the University of Miami.^[2] J. J. Ochse and Nelly's husband, Marinus Johannes Dijkman (1907–1970),^[7][8][9] both became professors at the University of Miami^[3][10] and established the University of Miami's department of tropical agriculture. Marinus and Nelly Dijkman built the first orchid house at the Fairchild Tropical Botanic Garden.^[3]

The United Fruit Company started a major banana breeding project in 1959. The company selected Paul Hamilton Allen and J. J. Ochse to lead collecting expeditions to Southeast Asia and the Western Pacific. From 1959 to 1961 their expeditions extensively collected banana germplasm —nearly 800 accessions of wild and cultivated species and varieties of bananas from Taiwan, the Philippines, Indonesia, Malaysia, Singapore, Thailand and Sri Lanka.^[11]
