Sweet potatoes are a versatile and nutritious addition to any vegetable garden. Contrary to popular belief, they are not related to regular potatoes; they belong to the morning glory family and grow from cuttings, which are stems that develop into roots. In this guide, we’ll walk you through the process of growing your own sweet potatoes from store-bought potatoes, allowing you to grow your favorite varieties inexpensively.
Choosing your sweet potato

When choosing store-bought sweet potatoes, consider choosing varieties other than the common orange types found in regular supermarkets. Asian markets often offer a diverse selection with unique flavors and colors. Varieties like Murasaki or Okinawa sweet potatoes can add a delicious touch with their purple skin and flavorful white or purple flesh.
Timing is crucial
Understanding the right time to plant sweet potato cuttings is crucial. They thrive in warm, moist conditions but are sensitive to frost. Plan to start the process 60 to 90 days before planting them in the ground, allowing ample growing time. In frosty regions, wait until nights remain consistently above 50°F (10°C) before transplanting the cuttings.
Start the sheets
Start by creating an ideal environment for the sweet potato cuttings. Use a moisture-retaining potting mix and place the store-bought sweet potatoes halfway into the mix. Make sure the potting mix is sufficiently moist but not waterlogged. Cover the container with a slightly cracked lid to maintain humidity while allowing fresh air to circulate.
Rooting process
With patience and proper care, sweet potatoes will root, producing cuttings—the stems that will grow into vines. These cuttings contain nodes, the points from which roots and new vines grow. As the cuttings develop, they can be separated into individual cuttings, each containing nodes and roots.
Plant the cuttings
Once the cuttings are sufficiently rooted, they are ready to be planted. Choose an evening with mild weather to transplant them into prepared planting holes. Space the cuttings about a foot apart to allow ample room for growth. Water them thoroughly to ensure moisture retention during the initial establishment period.

Growth and maintenance
As the sweet potatoes slide into the soil, monitor their progress. Ensure they receive consistent moisture, especially in the early stages of growth. The cuttings will establish themselves, developing new leaves and roots as they adapt to their new environment.
Growing sweet potato cuttings from store-bought potatoes is a rewarding process that produces an abundance of this nutritious tuber. With proper timing, care, and attention to detail, one can harness the productivity of a single sweet potato, generating dozens of cuttings for a bountiful harvest. Experiment with different varieties and enjoy the satisfaction of growing your own sweet potato stash for your culinary delights.
Remember that every step of this process contributes to the success of your sweet potato crop. With dedication and a little patience, you’ll soon be able to enjoy the fruits—or rather, the tubers—of your labor.
