Although it is simple to put up your sweet potato vine plant, it does take some time for the sprouts to appear. “That absolutely nothing will happen for the first four weeks is the one thing I wish I had known before I started this. According to Canning, the dish will be little more than a potato in water. “However, as soon as it begins to develop roots, it will quickly begin to vine.
Since it takes so long, Canning advises trying a few different sweet potatoes because not all of them will end up sprouting stems. Put those in the compost bin if they stop sprouting after a few months.
Canning advises changing the water at least once a week to prevent mold and stink when a fresh plant finally flourishes. So kick back and unwind as your sweet potato grows easily.
Sweet Potato Vine Plant: Step-by-Step Instructions
1. Grab a sweet potato and set it in a vase or cup of water. The sweet potato’s base ought to be submerged in water. Use toothpicks to support it on the rim of the cup or vase so that it will stay in place.
2. Watch for the sprouting of the potato. Normally, this takes four weeks.
3. The vines quickly spread out once the potato sprouts. Please enjoy your new plant! The vines can be strung around bookcases, on wall hooks, or on a dresser.
No concerns if your potato doesn’t sprout. Sometimes it requires a few tries. You can quickly have the sweet potato vine plant of your dreams if you follow these instructions with another potato.
How do you grow a sweet potato indoors?
If you don’t end up eating your sweet potatoes and would like to try growing one at home, I strongly advise you to do so. Surprisingly, I’ve read that a single sweet potato can yield up to 50 slips. These so-called “slips” are only tuber shoots. The potato can sprout without being submerged in water, but once you notice them, I’d put the potato in a jar of water.
The potato can be held in place with toothpicks so that it doesn’t fall into the water entirely. All that should be immersed is roughly one-third of the sweet potato. Put it on a windowsill, and change the water every second or third day. If not, the water will get quite foul.
The potato’s roots will resemble those below in a few weeks as the leaves begin to emerge and unfold. You can either continue to twist off some of the slips, plant them in a shallower jar of water, and wait for a few days for the roots to fully develop, or you can move your potato to a larger jar for a little bit longer. Once that has occurred, you can start transplanting some of the slips into a sizable pot filled with loose, well-draining potting soil (given they have a significant enough root system). Usually, I’ll plant mine in the biggest pot I can locate. Since these are underground creatures, you want to harvest the largest potatoes you can.
Give the slips plenty of water when you plant them. For the first two weeks until they were properly established, I was giving mine a thorough bath every day, maybe every other day. You may harvest sweet potatoes in around three to four months if you give them lots of sunlight and enough water.
In 4 months, I harvested these delicate but delicious blooms from my indoor container garden. That is A LOT of work for very little reward, but the potatoes made a wonderful breakfast and were a lot of fun to cultivate at home.
How long is the lifespan of a sweet potato plant?
The Texas A&M University System’s Joseph Masabni and Stephen King Assistant Professor, Extension Horticulturist, and Former Associate Professor, Department of Horticultural Sciences
Beta-carotene, which is easily processed by the body into vitamin A, is found in abundance in sweet potatoes (Ipomoea batatas), especially the types with orange flesh. The plant, which belongs to the Convolvulaceae or morning glory family, also makes bright flowers and trailing vines that are frequently utilized as groundcovers.
The sweet potato is a perennial plant that originated in the tropical Americas and has a lifespan of more than two years. It is considered a warm-season annual when grown in the United States (a plant that completes its life cycle in 1 year).
In terms of sweet potato production, Texas ranks seventh in the nation. Van Zandt County in East Texas is where most of the production is centered.
Varieties
There are numerous types of this root crop, some bred for their ornamental vines and others for their delectable potatoes (Fig. 1). The most widely grown food kinds in Texas are Beauregard, Centennial, Jewell, and Vardaman, with Beauregard being the most well-liked.
Climate
Texas is a major producer of sweet potatoes since the state’s hot days and cool nights are excellent for their growth. Sweet potatoes can withstand a lot of heat. As long as the soil temperature is higher than 55°F, they can endure minor frosts as well.
Site selection
A warm environment and full sun are necessary for sweet potatoes. They must be sown on fine sandy loam soil that drains well and has a pH range of 5 to 7.5 that is slightly acidic. This enables the sweet potato to grow without difficulty and prevents it from staying in a damp environment, which promotes rot and illness.
Soil preparation
Get a soil test done before you plant. It might simply require nitrogen. Except for the eastern counties with sandy soils and 40 to 60 inches of annual rainfall, which may lack potassium, most of Texas has ample phosphorus and potassium in the soil.
Compost or a complete fertilizer should be added to the soil. The only fertilizer required will be this. To ensure that the soil drains well and warms up soon in the early spring, cultivate it into beds that are 3 to 4 feet apart and 8 inches high (Fig. 2).
Propagation
Sweet potatoes are grown using slips, also known as vine cuttings, unlike other plants. Slips can be made at home, bought at a nearby garden center, or acquired from websites.
Purchase disease-free, healthful sweet potatoes from a neighborhood grocery to make slips. Cut them in half after cleaning them. Use toothpicks to suspend each half over a water-filled jar so that one half is immersed in the liquid. Give the sweet potato a window-side location for warmth and light. In the coming weeks, the top will start to sprout shoots (Fig. 3).
Planting
The best time to plant is when the soil temperature is over 65 degrees Fahrenheit at planting depth in the spring and at least 150 days before the projected soil temperature of 55 degrees Fahrenheit in the fall.
Till the vines have completely engulfed the earth, keep the beds clear of weeds. Maintaining a weed-free area will increase produce amount and quality at harvest, especially in the first 40 days following planting.
Fertilization
To find out how much nitrogen (N), phosphate (P), and potassium (K) are required, check the findings of the soil test. Commercial fertilizer recommendations for sweet potatoes typically call for 50 pounds of N, 70 pounds of P, and 70 pounds of K per acre (50-70-70). That’s roughly similar to 2 ounces N, 2.5 ounces P, and 2.5 ounces K for a 100 square foot planting area in a garden.
Check the bag’s formulation to establish how much fertilizer to use, then multiply the required number of ounces by the formulation’s percentage. For instance, if the bag specifies its composition as 13-13-13, the precise quantity of nitrogen required is:
Additionally, this fertilizer will provide 2 of the required 2.5 ounces of phosphate and potassium. You will need to add extra amounts of phosphorus and potassium separately to make up the difference, using bone meal (0-12-0) for the phosphorus and a source of potassium such muriate of potash (0-0-60).
Even though an additional 4 ounces of nitrogen will be added, an alternative would be to apply 19 ounces of 13-13-13 to obtain the total amount of phosphorus and potassium required. Watering Each season, sweet potatoes require 10 to 20 inches of water. You will need to water them because rain only occasionally falls throughout the season, especially at first during the slip establishment stage. During their first month of establishment, transplanted slips are highly susceptible to water stress.
In the final two to three weeks before harvest, avoid watering to prevent the tubers from decaying.
Harvesting
The epidermis of the sweet potato root is thin and readily injured during harvest. Take care not to bruise the roots with a hoe, shovel, or other harvesting tool. The skin will be damaged even if the potatoes are dropped into a harvest bucket.
The best time to harvest sweet potatoes for backyard gardeners is right before or right after the first fall frost. Sweet potato roots have reached maturity when their leaves turn yellow, signaling the end of growth. The moment is right for harvesting.
How is a sweet potato plant maintained?
Ipomoea batatas, often known as the sweet potato vine, grows well in hot, tropical regions and is a decorative leaf plant frequently used as a backdrop for floral arrangements. If the plant encounters hard freezes below 32 degrees Fahrenheit, the perennial will wither and die (0 C.). However, it is simple to store the tubers for a later season and in some cases the entire plant. You can overwinter decorative sweet potatoes by bringing them inside, hemming them in where it doesn’t typically get cold, or by gathering and storing the tubers.
Heeling in Sweet Potato Vines over Winter
If your area doesn’t frequently experience prolonged freezes, you can just bury the container the vines are growing in in mounded soil. Then trim the vine to just a few inches (5 cm) in length, and cover the container with a thick layer of mulch to function as a blanket and safeguard the roots. This is one method of preparing a sweet potato vine for winter.
When warm weather arrive, the plant should regenerate as long as the tubers don’t freeze. Although the vegetation may wither, the tubers are where the leaves and stems for the following spring will come from.
When nighttime short freezes occur, you may also just cover the buried container with burlap or a heavy blanket. Pull it aside so the plant can absorb solar energy during the day. Keep in mind that winter care for heeled in ornamental sweet potatoes includes occasional watering. As they are not actively developing in the winter, the plants will only require watering once or twice a month.
How to Overwinter Sweet Potato Plants Indoors
Simply bringing a sweet potato vine indoors is another method of winterizing it. Again, in regions without prolonged frost, you can frequently just move the tubers into a shed, garage, or other unheated building to keep them from freezing.
It is advisable to put the vines inside the house in cooler climates, but check them first for insects. If any little insects are found, treat with horticultural soap and give the area a thorough rinse. Cut the vines back to a height of 6 inches (15 cm), then remove the tubers and repot them in quality potting soil.
Put the containers in a window with natural light after watering them. When all threat of frost has passed, gently reintroduce sweet potato vines to the outdoors by keeping them relatively moist over the winter.
Overwintering Ornamental Sweet Potatoes as Tubers
You can always dig up and store the tubers if you don’t have the room or want to care for a vine during the winter. The tubers must be kept just barely damp; otherwise, they will dry out and stop sprouting.
Take the tubers out of the container and arrange them separately. Any remaining foliage should be removed. Area the tubers in a cool, dark place after covering them with newspaper or well-moistened peat moss.
To keep the tubers moist, check on them once a week, and mist them if required. It’s a bit of a balancing act because the tubers can’t completely dry out and too much moisture can lead to mold growth and tuber damage. Today’s buzzword is moderation.
Replant the tubers in organically rich containers or beds that have been prepared in the spring. You will soon have your sweet potato vines’ rich hues and tastefully clipped leaves once more.
The sweet potato vine can it grow inside?
You might try one of three techniques to overwinter sweet potato vines. All types will respond to these techniques.
Therefore, you can utilize the same procedures whether you have a hybrid, variegated, purple, or the ordinary chartreuse variety.
- Sweet potato vines in pots can be kept inside as houseplants.
- You can store the tubers and let the plants become dormant.
- Cuttings can be taken and brought inside for the winter.
How can a sweet potato plant be started in water?
Put the sweet potato in a water-filled jar. By inserting toothpicks into the sides, you may keep the top third of the potato visible. Ideally, the pointed end is submerged in the water. A vine with multiple stems will start to sprout in a few weeks.
Are sweet potato slips light-required?
This wholesome, sweet-tasting root vegetable can be abundantly harvested from just a few sweet potato plants. Northern regions can succeed with some types, yet they are more frequently produced in the South as they need warm weather. Discover the best sweet potato kinds as well as how to plant, care for, and harvest them.
About Sweet Potatoes
The morning glory family includes the tropical plant known as the sweet potato. You can see the similarity between the foliage and blossoms of a sweet potato vine and a morning glory. Despite their name, they are not related to nightshade plants like potatoes. The edible section of sweet potatoes is a tuberous root rather than a real tuber, which is another distinction between them and “regular potatoes (which are technically modified plant stems).
This root vegetable has a jacket of coppery skin over its deep orange flesh. Sweet potatoes are frequently served roasted whole or boiled and mashed. Or you may use them as pie filling.
This tropical crop is heat- and drought-tolerant and has few pests or illnesses, although it does require at least four months of warm weather and warm soil. There are now several short-season types of sweet potatoes, despite the fact that they are typically more of a Southern crop. When cultivated in sandy soil or raised beds with a black plastic mulch to keep the soil warm, they can be grown in the North (even in certain parts of Canada!).
Sweet Potato Slips
Keep in mind that sweet potatoes are not raised from seeds. Instead, slips, which are sprouts made from mature sweet potatoes, are used to cultivate them. Slips are frequently offered through neighborhood garden centers and nurseries, as well as by local farmers at farmers markets and mail-order businesses. Or you might start your own (see how below).
Make sure you have a long enough growing season to really grow sweet potatoes before ordering slips. The majority of cultivars take between 90 and 120 days to maturity. Check your frost dates and growing season duration. Additionally, remember to schedule your order to coincide with your planting dates!
Pick a location with well-drained soil that is sunny. Sweet potatoes don’t have many preferences, but they do like sandier soil. For their roots to penetrate the soil, they require a lot of air space. Consider planting on raised beds if your soil is clay, rocky, or compacted.
To create healthy, loamy soil down to 8 to 10 inches, add compost, perlite, and/or coconut coir to the growth area. Avoid adding animal manure, even pelleted chicken manure, as it may cause your roots to become spindly or discolored. Additionally, stay away from high nitrogen fertilizers, which promote luxuriant leaf development at the expense of the roots that are tasty.
When to Plant Sweet Potatoes
- When the soil has warmed to at least 65F or 3 to 4 weeks after your last spring frost, plant slips outside (18C). The minimum temperature at night should be 55F. (13C). The trick is to plant them early enough to give them enough time to mature, but not too early that a late spring frost kills them.
- Because they are so sensitive, immature sweet potatoes should be protected from any late frosts or cool nights (lower than 55F/13C). Cover them with row covers or plastic milk bottles, taking them off throughout the day.
- Unpack the slips as soon as possible if you purchased them via mail order. You can revive the roots by submerging them in water for about a day. As soon as the conditions are suitable, plant them.

How to Grow Your Own Sweet Potato Slips
Instead of purchasing slips, you may make your own, but it takes more work. This is how:
- Look for undamaged, smooth, organic sweet potatoes at the grocery store or farmers market around 8 weeks before the last day of your spring frost. Make sure to inquire about the variety and confirm that it is one you want to cultivate.
- Put the whole sweet potatoes in containers or pots with at least 3 inches of light, organic soil that is also well-draining. Space each sweet potato out by about an inch or two.
- Add a couple inches of extra soil and lightly cover. Water the soil now and as needed to keep it moist but not drenched.
- Keep the soil and the space between 75°F and 80°F, either in the sun or with artificial light. If required, use a heating mat; sweet potatoes do well in warm environments.
- Slips (shoots) will soon protrude from the ground.
- The slips should be between 6 and 12 inches long with numerous leaves and roots after roughly 6 to 8 weeks.
- Sweet potatoes with roots still attached should have their slips removed. (Remove the slip and submerge it in water if no roots have formed on the slip itself; roots should appear in 1 to 2 weeks.)
- Keep the slips moist until the appropriate planting time by standing them in potting soil or sand if it is still too early to plant outside (3 to 4 weeks after last frost).
- For 1 to 2 weeks, expose the slips to filtered sunshine outside throughout the day to “harden off” (before planting outside).
How to Plant Sweet Potatoes
- Make elevated mounds that are between 6 and 8 inches tall and 12 inches wide.
- Plan 3 feet between each mound to give vines room to spread out.
- When the soil temperature reaches 60 degrees Fahrenheit on a warm, cloudy day, plant the slips (15C).
- Leave only the top leaves by breaking off the lower ones.
- Set the slips deep enough to completely enclose the roots, stem, and leaves. On the nodes, sweet potatoes will grow.
- To ensure that the plants have strong roots, water with a liquid fertilizer with a high phosphorus content and then liberally for 7 to 10 days.
