Sweet potatoes grow from something called “slips”. Those are the green vines that grow out of a sweet potato when it sprouts. They’re taken off and planted in the ground to create a new sweet potato plant. A single sprouting sweet potato can provide you with at least 15 slips (that’s a low estimate).
How do you know when sweet potatoes are ready to harvest?
Sweet potatoes are usually ready to harvest just as the ends of the vines begin to turn yellow, or just before frost in the North. To avoid injuring tubers, find the primary crown of the plant you want to dig, and then use a digging fork to loosen an 18-inch wide circle around the plant.
How do sweet potatoes grow in the ground?
Sweet potatoes grow in the ground as tubers, where the plant stores starches made of sugar. These tubers are the part of the plant that is harvested and eaten. Tubers will eventually sprout and produce slips, which can be planted to grow more sweet potato plants.
How many sweet potatoes do you get from one plant?

Yields are based on how much care you give your plants in their growing season and the type of potatoes you choose to grow.
How do sweet potatoes reproduce?
The plant reproduces in three ways: from seed, from the actual storage roots, or from the plant vines. Sweetpotato is cultivated by vegetative propagation. Growers take stem cuttings from the vines, which then root and form new storage roots. Botanical seed is used in breeding programs.
What does it mean when a sweet potato plant flowers?
Flowers on a potato plant indicate that its tubers (the edible part of the plant that grows underground) are starting to form. After you see flowers form on your potato plant, you know that the plant is doing well, and that it is getting closer to harvest time.
Do sweet potatoes grow underground?

Do sweet potatoes need a trellis?
A trellis can also be used for growing sweet potatoes vertically. This space-saving design can be utilized in the garden or with container-grown sweet potatoes. Since sweet potatoes tend to be creepers rather than climbers, choosing the correct trellis is essential for success.

Sweet potatoes mature in 90 to 170 days and they’re extremely frost sensitive. Plant in full sun three to four weeks after the last frost when the soil has warmed. Make holes 6 inches deep and 12 inches apart. Bury slips up to the top leaves, press the soil down gently but firmly, and water well.
Can you eat freshly dug sweet potatoes?
You should resist the temptation to dig and immediately eat sweet potatoes, as fresh ones are more starchy than sweet, and don’t bake as well as cured ones.

Should I pick the flowers off my potato plants?
When you see flowers on your potato plants, I recommend cutting them off for two main reasons. This tells the plant to stop sending its energy to seed production and to keep producing tubers. Pruning is such an effective way to direct the plant where you want its energy to go.
