Growing Sweet Potatoes In Arizona

To grow the best, you must have the resources — like the greenhouse — and know information on the cutting, timing, and the number of potatoes you can get from a plant. 

Sweet potato has a very interesting history. The earliest harvests of this crop dated back from 750 B.C. in Peru, but the cultivation of sweet potato started in 1,850 B.C. When colonizer Christopher Columbus landed on the New World in the 1400s, sweet potatoes had established themselves as a popular food source in both Central and South America.

These sweet potatoes are abundant in fiber and they also contain essential vitamins and minerals, including calcium, selenium, and iron. Plus, these are also perfect sources of Vitamins B and C.

How Do You Grow Sweet Potatoes In Arizona?

Growing sweet potatoes in Arizona involves dedication. According to a university in the state, the warmer regions of northern Arizona are perfect areas where you can grow the sweet potato. However, due to limitations, greenhouses are recommended to plant these crops right within your gardens. They belong to the morning glory or the Convolvulaceae family. 

There are two various types of sweet potatoes, and these are:

  • Soft-fleshed – Have orange and sweet flesh known as yams, but are farther from what sweet potato is today
  • Firm-fleshed – Notable for their light orange, light yellow, and white flesh homeowners can store for longer periods 

The soil required for these sweet potatoes must be moist, fertile, and nutrient-rich. Remember that you have to prepare the soil by adding in a maximum of six inches organic matter well-composted and a maximum of two pounds of fertilizer, all-purpose. Do not go overboard, because these must be added per every 100 square feet. 

Place the soil to its eight-inch depth, and rake the soil to provide a maximum of 10-inch tall raised beds for better drainage and root development. 

Growing sweet potatoes in Arizona entails that you know they are cultivated from cuttings in their stem. This means that they are grown from the root’s plant sprouts. 

You can encounter varieties grown from cuttings from the vine. If you require fewer plants, you may grow these from roots suspended in water containers with toothpicks. When you require more plants, you may arrange several roots from the sweet potato about an inch apart covered with approximately two inches of light soil or sand.

Then, begin adding two inches of sand at most as the shoots begin the sprout. Make sure that the bed soil is maintained on the moisture in the sprouting period, but avoid having them waterlogged. The temperature of the soil must be from 70 degrees to 80 degrees Fahrenheit. What are the things you must know more about sweet potatoes?

Sweet potatoes are ingredients to a variety of dishes. However, you may find yourself on a limited spree when you buy the potato from the grocery store. Aside from being pricey, you will always prioritize essential ingredients over crops of this kind.

It is why cultivating the crop right from your home with the greenhouse will save you with the money and the resources. Here are more tips to grow them right.

Initially, you can put these sweet potatoes inside a jar of water. Half of the sweet potatoes must be submerged in the water, leaving the rest set aside. Those underwater will be sprouting roots in the coming weeks while those above the water will grow the sweet potato slips or the sprouts. Should you find your crop a little bit skinny, then you may use a toothpick, just like how they are done in recipes, to keep them away from falling down. 

Store the jar with the potatoes inside where it is warm. The ideal temperature is 80 degrees Fahrenheit. The warmer the area, the better it would be. Many house owners want to place them in their dining room’s cupboard just beside their heat vent. Warmth over lighting is what these sweet potatoes are about.

Before they can grow “slips,” it may take a month-long or more, and you must always keep them in check once they have started to pop out. The sweet potatoes may also grow roots before they grow the slips so make sure to check on these as well. Depending on the “mood” of the potatoes, these will grow just from anywhere between a week to two months.

How Long Can You Keep Cutting Sweet Potatoes?

Keep your cut and cooked food sources in the refrigerator for up to seven days. Do not forget to use an airtight container to store these sweet potatoes within an hour after cooking. While they are hot, place them in the fridge should you want to immediately keep them after this.

A note though: Make sure that you label the storage container with the “made on” complete data to remind you of how long they will be good for. The last thing you want to happen is to encounter these sweet potatoes wasted from the gardening because you’ve missed on the storage time.
