turmeric

An interesting question came in to Ask Gardenerd this week: "My friend and I both live in central South Carolina. Last year we planted turmeric plants in our yards. Now we realize that we need to know how and when to harvest these plants. What should they look like? Do they need to be stored for a time before using the root? (like some potatoes and onions). Please give us some general ideas and tips. Thank you. Evelyn" We love…
