AUBURN, Ala. (AP) -- Auburn University's horticulturist is hoping an experimental procedure can help the historic trees at Toomer's Corner.
Gary Keever on Monday oversaw an experimental procedure in which the trees received sugar injections.
A Tennessee-based company drilled a series of 49 small ports around the circumference of the oaks and then siphoned in a carbohydrate-rich cocktail of fructose, glucose and sucrose using flexible tubing.
Jim Cortese, owner of Cortese Trees Specialists and a board-certified master arborist, said the sugar solution was necessary because of reduced photosynthesis due to the herbicide levels they were exposed to
Harvey Updyke, a University of Alabama fan, is accused of poisoning the trees with a powerful herbicide shortly after the 2010 Iron Bowl.
