Fire Blight is a bacteria that infects apple trees, especially in the Mid-Atlantic region. It causes blossoms to whither and die, and limbs to rot. The infectious cankers of fire blight can destroy an entire tree if not caught in time. It is difficult to predict when or if fire blight will strike and is very costly to control. Planting varieties that are resistant to this disease is a wise decision.
