I planted some attractive sweet potato vines in a 6 inch deep pot -- about 1.5 ft in diameter. I didn't expect them to grow extensively. However, with watering regularly, they certainly are growing like crazy. I'm wondering if I should take the time to try to harvest sweet potatoes from them.
Is it feasible to harvest an appreciable amount of sweet potato from the pot? Or would it only be feasible to grow sweet potatoes in a more traditional vegetable garden?
