Chicory is a perennial forb that is long-lived. Chicory can be very palatable and nutritious, as well as, rich in minerals when properly managed. Chicory has a deep tap root, allowing it to survive most droughts. 
It is best to rotationally graze, or occasionally mow to help keep it vegetative.
Chicory should not be seeded in hay fields. It is often too high in moisture content and can cause spoilage. 
Seed 2 - 3 pounds per acre at 1/4 - 1/2" depth
