Sweet potatoes are not heavy feeders, but it's important to give them balanced nutrition, typically with proper soil preparation. Overfeeding tends to promote growth of foliage rather than tubers. The best approach is to add compost to the beds before planting the sweet potatoes.
Once established, sweet potatoes will tolerate growing in dry soil. It's best to keep it evenly moist with 1 inch of water given once a week. Don't water your sweet potatoes during the final three to four weeks prior to harvest to prevent the mature tubers from splitting.
You can start digging up the potatoes as soon as they are big.
