How to Grow Sweet Potatoes in Water
Step 1: Choose Sweet Potato Slips
To begin growing sweet potatoes in water, you will need to obtain sweet potato slips, which are small sprouts that grow from sweet potatoes. You can purchase slips from a gardening store or use sweet potatoes from your local grocery store.
Choose sweet potatoes that do not have any cuts, bruises, or signs of disease and are firm to the touch. Cut the sweet potatoes in half and suspend them in water, cut side down, using toothpicks or skewers.
Step 2: Allow the Slips to Sprout
Place the sweet potato halves in a well-lit area, such as a windowsill or under grow lights. The slips should begin to sprout within a few days to a week.
Step 3: Prepare Your Container
Choose a container that is at least 6 inches deep and has a capacity of at least 2 gallons of water. Fill the container with clean water, leaving enough space for the sweet potato slips.
Step 4: Plant the Sweet Potato Slips
Once the sweet potato slips have sprouted, carefully remove the toothpicks or skewers and place the slips into the container of water. The slips should be submerged up to their leaves, but not fully covered.
Step 5: Maintain Proper Growing Conditions
Place the container in a warm, well-lit area, such as near a sunny window or under grow lights. Change the water every 2-3 days to ensure it stays clean and fresh. Monitor the roots for signs of excessive growth or root rot, and adjust the water level as needed to maintain the right balance between air and water.
Step 6: Harvest Your Sweet Potatoes
After several months, your sweet potatoes should be ready to harvest. Remove the slips from the water and carefully dig up the roots. Rinse the sweet potatoes under running water and allow them to dry out in a warm, well-ventilated area before storing them in a cool, dry place.
