Planting sweet potato sprouts is a simple and cost-effective way to expand your sweet potato harvest.

To start the process of planting sweet potato sprouts, you will need mature sweet potatoes that are ideally organic and have not been treated with any growth inhibitors. Look for sweet potatoes that have multiple well-developed eyes or nodes.

  1. Selecting Sweet Potatoes: Choose healthy sweet potatoes that are free from any signs of disease or rot. Look for ones with smooth skin and vibrant color. Avoid selecting sweet potatoes that have soft spots or mold.

  2. Curing Sweet Potatoes: Before sprouting, it is important to cure sweet potatoes to promote the development of sprouts. Curing involves storing sweet potatoes in a warm and humid environment for several weeks. Place the sweet potatoes in a well-ventilated room with a temperature between 80-85°F (27-29°C) and with humidity levels of around 85-90%. This process helps to toughen the skin, enhance flavor, and stimulate sprouting.

  3. Creating Sprouts: After curing, the sweet potatoes will start developing sprouts or "slips" from their eyes. You can speed up the sprouting process by placing the sweet potatoes in a container filled with water. Make sure to only submerge the bottom one-third of the potato in water while keeping the top two-thirds dry. Place the container in a warm and sunny location. Within a few weeks, the sweet potato will start growing sprouts that are around 4-6 inches long.

  4. Separating Sprouts: Once the sprouts have grown to a suitable length, you need to carefully separate them from the sweet potato. Gently twist or pull the sprouts to detach them from the parent sweet potato. Be cautious not to damage the fragile roots.

Techniques For Planting Sweet Potato Sprouts

Now that you have prepared your sweet potato sprouts, it’s time to plant them. The planting technique you choose will depend on your garden space, available resources, and the desired yield.
