How long does a sweet potato plant take to grow?
The trick is to plant them early enough for them to mature properly, but not early enough for them to get killed by a late spring frost. Before planting, make sure you have a long enough growing season. Most varieties will take about three to four months to mature – about 90 to 120 days.
Can I just plant a whole sweet potato?
“Slipping” is when you grow little baby plants out of a whole sweet potato. Now, you can just bury whole sweet potatoes very shallowly if you like, but many gardeners prefer to grow slips from the tubers and then plant the slips. It’s easy, fun, and one of the best gardening activities for kids.
How many sweet potatoes will one plant produce?
Sweet potatoes are grown from rootable cuttings, often called slips. If you’ve never grown sweet potatoes before, it can be great fun to grow your own slips from small or medium-size sweet potatoes purchased at the market. One sweet potato will produce between three and five slips.
Can you grow sweet potatoes from store bought?
Yes, you can grow sweet potatoes in our area. You can start your own slips, sprouts from an existing sweet potato, by purchasing “seed” sweet potatoes from a nursery; or you can start slips from tubers purchased from the grocery store.
Can I plant a sweet potato that has sprouted?
No, you should not plant an entire sweet potato that has sprouted. Instead, you should wait for the sprouted parts to grow longer and develop roots. Don’t plant the entire sprouted sweet potato – wait until the sprouts develop roots and turn into slips. Then, you can remove them and plant them!

How do you plant sweet potato slips in pots?
It is important to have a good soil mix when planting in your containers. Using a container mix amended with compost, sand and a fertilizer high in potash is ideal.

How do I 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.
What happens if I plant sweet potatoes?
Planting whole sweet potatoes will give you vines and roots, but — because the resulting vines are so close together — the roots you harvest will tend to be stunted.
Do you plant potatoes with the eyes up or down?
Basically, the only thing to remember when planting potatoes is to plant with the eyes facing up. Here’s a little more detail: Small seed potatoes that measure 1 to 2 inches (2.5 to 5 cm.) If your seed potatoes are larger, cut them into 1- to 2-inch chunks, each with at least one good eye.
Do sweet potatoes grow underground?
Like regular potatoes, sweet potatoes are starchy tubers that form underground. Sweet potato plants are sensitive to cold, so they should not be planted outdoors until the soil has warmed to at least 60 degrees F.
