How to propagate sweet potatoes in water for many roots and tubers

Propagating sweet potatoes in water can be a fun and rewarding process, leading to the development of roots and tubers. Here’s a step-by-step guide on how to propagate sweet potatoes in water:

Materials Needed:

  1. Sweet potato with “eyes” or sprouts
  2. Clean, clear glass or jar
  3. Toothpicks or wooden skewers
  4. Water
  5. Optional: Rooting hormone (for faster rooting)

Steps:

  1. Selecting a Sweet Potato:
    • Choose a sweet potato with visible “eyes” or sprouts. These are the small buds or shoots that will grow into vines and roots.
  2. Preparing the Sweet Potato:
    • Rinse the sweet potato under cool, running water to remove any dirt. Avoid using sweet potatoes treated with growth inhibitors, as these may hinder the sprouting process.
  3. Inserting Toothpicks:
    • Insert toothpicks or wooden skewers into the sides of the sweet potato, about one-third of the way down from the narrower end. These will help support the sweet potato above the water.
  4. Positioning Over the Glass:
    • Rest the sweet potato on the rim of a glass or jar, ensuring that the lower two-thirds of the sweet potato is submerged in water. The toothpicks should support it in place.
  5. Adding Water:
    • Fill the glass or jar with enough water to submerge the lower part of the sweet potato. The water should cover the nodes where roots will develop.
  6. Place in a Warm Location:
    • Position the setup in a warm location with indirect sunlight. A windowsill is a good choice. Ensure that the sweet potato receives sufficient light for healthy growth.
  7. Change Water Regularly:
    • Change the water every few days to keep it fresh. This prevents the growth of algae and maintains a healthy environment for root development.
  8. Optional: Use Rooting Hormone:
    • If you want to speed up the rooting process, dip the cut end of the sweet potato in rooting hormone before placing it in water.
  9. Wait for Roots to Develop:
    • Over the next few weeks, you should see roots developing from the nodes of the sweet potato. Wait until the roots are a few inches long and are well-established.
  10. Transplanting:
    • Once the roots are sufficiently developed, carefully transplant the sweet potato into soil or a larger container, covering the roots with a thin layer of soil. Leave the shoots exposed.
  11. Care for Growing Vines:
    • Provide the growing sweet potato vines with ample sunlight and a warm environment. Regularly water the soil to keep it consistently moist.
  12. Harvesting Tubers:
    • As the vines grow, sweet potatoes will develop underground. Harvest them when the vines have started to yellow and die back. Gently dig around the base of the vines to reveal the tubers.

Tips for Success:

  • Patience is Key: Sweet potatoes may take several weeks to develop substantial roots, so be patient and allow the process to unfold.
  • Avoid Disturbing Developing Roots: Handle the sweet potato and the developing roots with care to avoid damaging the delicate root system.
  • Provide Adequate Light: While propagating in water, ensure the sweet potato receives bright, indirect light for optimal root development.
  • Maintain a Warm Environment: Sweet potatoes thrive in warm conditions. Keep the environment consistently warm for successful propagation.

By following these steps, you can successfully propagate sweet potatoes in water and eventually transfer them to soil for continued growth and tuber development. Growing sweet potatoes at home can be a rewarding experience, and you’ll enjoy the harvest of fresh, homegrown tubers.
