If you want a vegetable that grows a beautiful trailing plant, makes a lovely temporary ground cover, and produces a delicious, versatile, organic food all in one, the sweet potato is the vegetable you are looking for. Below are some helpful vegetable gardening tips for sweet potatoes.
There are moist and dry varieties of sweet potato flesh. For your home garden, the best choice is one of the moist varieties like the Centennial, or the Georgia Jet sweet potato.
It is recommended that you plant the root sprouts in ridges that are approximately 10 inches high, with each root sprout separated by about 3½ feet.
To get the best formed sweet potato tuber, it is recommended that they be planted in organic compost, avoiding nitrogen-rich fertilizers.
Plant your sweet potatoes in full sun and give them 90 to 170 days to mature, depending on the variety you choose to plant.
Yellow leaves on the plant indicate they are ready to be harvested. However, the longer you can leave them in the ground, the more tubers you will get and the higher the vitamin content will be. If the leaves get frozen and turn black, it is time to get your sweet potatoes out of the ground or they will rot. Cure them in the sun at around 90 degrees for up to 15 days. When sweet potatoes are properly cured and stored at 55 degrees, they should keep many months.
