There is a lot to learn about the sweet potato. Sweet potato cultivation dates back to 1,850 B.C., while the earliest known harvests in Peru were from 750 B.C. A popular food source in both Central and South America when Christopher Columbus arrived in the 1400s, sweet potatoes were already well-known in the New World.
These sweet potatoes are packed with fiber, as well as calcium, selenium, and iron, which are all necessary nutrients. In addition, these foods are excellent suppliers of B and C vitamins.
The texture of this food source is similar to that of a yam, making it easy to identify. The flavor is sweet, as the name suggests, but if you try it raw, you might get a taste of the freshness. The sweet potato tastes even better once it has been cooked.
1. Plant sweet potatoes at the correct time
Potatoes should be planted when the soil temperature reaches 65 degrees Fahrenheit, about two to three weeks after the last spring frost.
The Arizona Low Desert:
- From January to April, start preparing sweet potato slips inside.
- Sweet potato slips can be grown outside from March through June.
2. Prepare soil correctly before planting sweet potatoes
Sweet potatoes require acidic soil that drains well. Compost should be applied liberally on clay soils. A minimum of 8-10 inches of soil should be worked. It is also possible to cultivate sweet potatoes in raised beds or in huge pots. In the low desert, plant in a location that receives full sun and/or afternoon shade.
3. Plant sweet potato slips
Sweet potatoes, unlike many other vegetables, are not cultivated from seed. Instead, slips are used, which are mature sweet potato shoots that have been rooted. You can either grow your own sweet potato slips or buy them.
The long growing season of the low desert is ideal for most sweet potato types. Fast-maturing cultivars like “Beauregard” and “O’Henry” are good choices for areas with shorter growing seasons or higher elevations.
To the level of the uppermost leaves, plants with deep roots bury their slips. Allow 12-18 inches between each sweet potato plant. If your soil is deficient in phosphorus, you’ll want to use a high-phosphorus starting solution to help the plants establish strong roots.
4. Allow vines to grow for larger sweet potatoes
Even if you want to consume a few leaves every now and then, don’t cut back aggressive vines if you want to get the biggest yields. As the leaves receive more sunshine, the sweet potatoes grow larger. Sweet potatoes grow larger when exposed to more light and have more leaf surface area that receives direct sunshine.
Vegetation grown vertically up a trellis allows more sunshine to reach the leaves, resulting in larger sweet potatoes if space is limited.
Lift long vines out of the ground to prevent them from becoming entangled with the vines. Additional rooting depletes the main tubers’ energy, resulting in a large number of little tubers.
5. Water deeply, less often
Sweet potatoes need a lot of water when it’s hot and dry out there. However, the soil must be allowed to dry out between waterings. In comparison to soggy potatoes, sweet potatoes are more tolerant in dry environments.
6. Harvest sweet potatoes at the right time
Before harvesting sweet potatoes, keep an eye out for the following signs:
- When a crop is let to grow for a longer period of time, the yield is greater.
- Depending on the variety, sweet potatoes can be harvested 90-120 days after planting.
- Tubers should be at least 3 inches in diameter when they are harvested.
- Prior to the first fall frost, remove sweet potatoes from the vines.
- When the leaves and vines turn yellow, sweet potatoes are usually ready for harvest.
7. Harvest sweet potatoes correctly
The sweet potato vines should be cut back and the soil softened around the plant with a spade fork once you’ve decided to harvest them. Dig up the tubers with your hands by finding the plant’s major crown. Handle tubers with care to avoid damaging them by shaking off any soil. Sweet potatoes should be kept away of direct sunlight after harvesting. Keep sweet potatoes in their skins until ready to use. This will extend their shelf life.
8. Cure sweet potatoes before storing
Set sweet potatoes in a single layer (without touching) in a warm (80°F) and humid environment for 10-14 days to cure. In addition to healing scrapes and bruises, curing sweet potatoes aids in the conversion of their starches into sugars.
Sweet potatoes can be cured in a hot climate by following these simple steps:
Store sweet potatoes in a single layer in a plastic shopping bag (with holes cut in it for air) to keep them wet in a warm location WITHIN your house. Sweet potatoes will not be able to properly cure in the outside temps.
When the sweet potatoes are rubbed together and the skin is still intact, the curing process is complete. If potatoes are preserved too long, sprouting will occur. Once the potatoes have been cured, discard or immediately use any that have been bruised. For the longest shelf life, keep cured sweet potatoes in a cold, dry place (ideally between 55 and 65 degrees Fahrenheit).
COOL HEAT STORAGE TIPS FOR POTATOES:
Sweet potatoes’ storage life is significantly reduced if they are kept above 70°F. When it’s cool outdoors, keep sweet potatoes in a box in the garage, each one covered in newspaper. Bring the box inside to the coolest room after the temperature rises. Keep an eye on your potatoes and use any that appear to be sprouting or rotting as soon as possible.
How Do You Grow Sweet Potatoes In Arizona?
In order to successfully grow sweet potatoes in Arizona, you’ll need a lot of perseverance. Sweet potatoes thrive in the state’s warmer northern parts, according to researchers at a local university. However, due to limits, it is recommended that you employ greenhouses to grow these foods in your own backyards. They belong to the Convolvulaceae family, which includes the morning glory.
Sweet potatoes come in two varieties: red and white.
- Soft-fleshed yams have orange and delicious flesh, but they are far from the sweet potato we know today.
- For extended lengths of time, homeowners can preserve firm-fleshed fruit because of its brightly colored orange, light yellow, and even white flesh
Sweet potatoes require damp, healthy soil that is rich in nutrients. Remember to add six inches of well-composted organic matter and two pounds of all-purpose fertilizer to the soil before planting. Adding these is required for every 100 square feet of floor space.
Rake the soil to a depth of eight inches, then raise the beds to a maximum of ten inches in order to improve drainage and root growth.
To grow sweet potatoes in Arizona, you must know that they are grown from cuttings in their stem. That’s how they get their start: by taking cuttings from the root’s sprouts.
Cuttings from the vine might yield new varieties. If you only need a few plants, consider growing them from toothpick-suspended roots in water containers. If you want to grow more sweet potato plants, you can space the roots about an inch apart and cover them with two inches of sand or light soil.
As the plants begin to develop, begin adding two inches of sand at the most. Make sure the bed soil is kept moist during the sprouting stage, but avoid waterlogging. Soil temperatures should be in the range of 70 to 80 degrees Fahrenheit for best results. When it comes to sweet potatoes, what do you need to know?
How Long Does It Take To Grow A Sweet Potato?
Many different meals use sweet potatoes. However, if you buy the potato in the grocery store, you may find yourself on a limited shopping spree. In addition to being expensive, crops of this type will never be preferred above critical ingredients.
As a result, growing your own food in a greenhouse at home saves time, money, and other resources. Here are a few additional pointers on how to go about it.
The sweet potatoes can be stored in a water-filled container for the first few days. The rest of the sweet potatoes can be left out of the water, but just half of them should be immersed. The sweet potato slips or sprouts will appear on the surface of the water, while the roots will sprout on the submerged plants in the coming weeks. It is possible to use a toothpick to protect your crop from toppling over in the same way that it is done in recipes.
To keep the potatoes warm, keep the jar in a place that isn’t too cold. 80 degrees Fahrenheit is the perfect temperature for a good night’s sleep. It would be great if the area was warmer. It’s common for people to put them in their dining room’s cupboard right next to the heat vent. These sweet potatoes are all about providing comfort above providing light.
It may take a month or more before they begin to form “slips,” and you must always keep an eye on them once they begin to emerge. You may also want to keep an eye out for sweet potato roots before you see the slips. It can take anything from a week to two months for these potatoes to sprout.
How Long Can You Keep Cutting Sweet Potatoes?
For up to seven days, keep your sliced and cooked food sources in the refrigerator. Sweet potatoes should be stored in an airtight container within an hour of cooking. If you want to keep them right away, put them in the fridge while they’re still hot.
However, keep in mind that the “manufactured on” entire data should be labeled on the storage container to remind you how long they will be valid for. You don’t want to find these sweet potatoes rotting in your garden because you neglected to store them properly.
How Do You Grow Sweet Potatoes From A Sweet Potato?
In order to cultivate sweet potatoes in Arizona, you must be familiar with all of the stages involved. You’ll grow sweet potatoes after heat-sensitive plants like tomatoes and peppers. Warm air and warm soil are necessary.
Layering black thermal material in the garden bed will help warm the soil. Using cornstarch to make biodegradable plastic is an excellent option. If you don’t want to use the sweet potato slips, warm the soil to 10 degrees and start planting in two weeks or less.
Another question that comes up is how many sweet potatoes are produced from a single plant?
How Many Sweet Potatoes Do You Get From A Plant?
If you are looking at reselling these sweet potatoes so you can earn, or harvesting them so you can pursue them in the market nearby, you must know the number of potatoes you can grow from each plant. It also aids in the design of greenhouses and gardens.
The quantity of sweet potatoes you can grow from each plant is important if you plan on reselling them to make money or harvesting them to sell them in your local market. Your greenhouse or garden layout will also benefit from this information.
- This is the second step in rooting their slips.
- Next, we’ll need to get the soil ready.
- Planting is the fourth step.
- Step 5: Drink plenty of water and be careful
