"What Every Gardener Should Do in the Fall," with Che Axum, director of the Center for Urban Agriculture at the University of the District of Columbia.

When you say "tomato," Che Axum says "really big, juicy tomato." As director of the University of the District of Columbia's Center for Urban Agriculture, he oversees the university's Master Gardener, Urban Agriculture, and Specialty/Ethnic Crops certificate programs, helping to keep the city green and healthily fed. He'll be discussing essential steps that every gardener should take in the fall to have bumper crops in the coming year and to grow for nutrient density. He'll also take questions about dealing with poor soil, plant disease, and pests. (Tickets $10 at the door.)
