Tubers normally do not form until later in the season when the plant begins to prepare for winter. Allow them to keep growing. On average, it takes about 95 to 120 days after transplanting the slips to have mature sweet potatoes. The leaves on the plants will begin turning yellow and dying off when they are ready for harvesting.
