Dr. Manners attended Anderson College, earning the B. A. in chemistry and biology. From there, he went to the University of Florida for the M. S. and Ph. D. degrees in horticultural science, specializing in flowering physiology of tropical fruits. He has been teaching at FSC since 1981, and has specialized in fruit production (mostly citrus), as well as roses, and techniques of propagation of various crops. Since 1996, he has participated in 14 USAID-funded volunteer consulting missions to developing countries, to help alleviate their extreme poverty through education on better crop production methods. Countries include Ethiopia, Egypt, Armenia, Turkmenistan, Kyrgyzstan, India, Bangladesh, Mozambique, Nigeria, and Angola. He is very active in the preservation of heirloom genetic resources in roses, and is a trustee of the Heritage Rose Foundation.
