When should I harvest beets?

Question:

When should I harvest beets?

Answer:

Beets may be harvested when the roots are 1 inch in diameter.  However, the main crop usually isn’t harvested until the roots are 1½ to 3 inches in diameter.  (Beets larger than 3 inches in diameter are often tough and fibrous.)  Beets require approximately 50 to 70 days from planting until harvest.
