Kim Powell planned to retire in 2005 after thirty-plus years of service with Agricultural Extension and the Department of Horticultural Science at N.C. State University. Along with his teaching duties, he had been directly responsible for all Agricultural Extension professionals statewide. He had also hosted the UNC-TV show 'The Backyard Gardner' and a weekly call-in radio show on gardening. However, his retirement was delayed when he was asked to fill in as interim director of the J. C. Raulston Arboretum while a search was undertaken for a new director. The position was filled in December 2005.
