Sweet potatoes are a nutritious and versatile crop that can be a delightful addition to your garden. Starting sweet potato slips is a simple yet effective way to grow this delicious root vegetable. This guide will walk you through the process of creating slips from sweet potatoes, providing all the steps and tips you need to ensure a successful harvest.
Understanding Sweet Potato Slips
Sweet potato slips are the sprouts that grow from a mature sweet potato. These slips can be planted to produce new sweet potato plants. Starting slips from a sweet potato allows you to propagate your crop without buying seeds. This method is both cost-effective and satisfying, as you can grow a variety of sweet potatoes from a single tuber.
Step 1: Selecting the Right Sweet Potato
To start, choose a healthy, organic sweet potato. Organic sweet potatoes are preferable because they are free from chemical treatments that could inhibit sprouting. Look for a firm, blemish-free tuber that is not too old. Older sweet potatoes may have a reduced sprouting potential.
Step 2: Preparing the Sweet Potato
Clean the sweet potato thoroughly to remove any dirt. Place the potato in a jar or container filled with water. To keep the potato partially submerged, use toothpicks. Insert four or more toothpicks around the middle of the potato and rest them on the rim of the jar. This setup will ensure that only half of the potato is submerged in water, which encourages sprouting.
Step 3: Positioning the Potato
Place the jar in a warm, sunny location. A south-facing windowsill is ideal as it provides ample sunlight and warmth. Sweet potatoes need temperatures between 70-80°F (21-27°C) to sprout effectively. Make sure the spot you choose receives plenty of light to help the slips grow strong and healthy.
Step 4: Maintaining the Water
Keep the water level consistent and change it every few days to prevent mold and bacteria growth. Stagnant water can lead to rotting, so maintaining a clean environment is crucial for healthy slip development. Ensure that the water does not cover the entire potato but only submerges the bottom half.
Step 5: Waiting for Sprouts
Within a few weeks, you should start to see sprouts emerging from the potato. These sprouts are the slips that you will eventually use to grow new sweet potato plants. Allow the slips to grow until they reach a length of 4-6 inches (10-15 cm). The longer you wait, the more developed the slips will be, leading to stronger plants.
Step 6: Harvesting the Slips
Once the slips have reached the desired length, gently twist or cut them from the sweet potato. Be cautious not to damage the potato or the slips themselves. Use clean, sharp scissors or a knife to make a clean cut. You can remove multiple slips from a single potato.
Step 7: Rooting the Slips
After harvesting the slips, place them in a jar or glass of water, making sure the base of the slip is submerged. Keep the jar in a warm, sunny location as before. Change the water regularly to keep it fresh. In about a week or two, you should notice roots developing at the base of the slips.
Step 8: Transplanting the Slips
When the roots are 2-3 inches (5-7 cm) long, it’s time to transplant the slips into your garden or containers. Prepare a planting area with well-draining soil, as sweet potatoes prefer loose, sandy loam. Plant the slips 12-18 inches (30-45 cm) apart, burying them up to the base of the leaves. Water the plants thoroughly after planting to help them establish roots in their new environment.
Step 9: Caring for Sweet Potato Plants
After planting, ensure the sweet potatoes receive consistent moisture, especially during dry periods. Sweet potatoes prefer warm soil and will grow best in temperatures between 65-85°F (18-29°C). Apply mulch around the plants to retain moisture and suppress weeds. Fertilize with a balanced fertilizer or compost to encourage healthy growth.
Step 10: Harvesting Sweet Potatoes
Sweet potatoes are typically ready to harvest 90-120 days after planting, depending on the variety. Harvest them before the first frost to prevent damage. Gently dig around the plants to avoid bruising the tubers. Cure the harvested sweet potatoes in a warm, dry place for a few weeks to enhance their flavor and shelf life.
Tips for Success
- Choose the Right Variety: Different varieties of sweet potatoes have varying growing requirements. Select a variety suited to your local climate and growing conditions.
- Rotate Crops: Avoid planting sweet potatoes in the same spot year after year to prevent soil-borne diseases and pests.
- Monitor for Pests: Keep an eye out for pests such as sweet potato weevils and fungal diseases. Take action promptly if you notice any issues.
- Use Mulch: Mulching helps retain soil moisture and keeps weeds at bay, providing a more favorable environment for your sweet potato plants.
- Provide Support: If growing in containers, ensure they have adequate support as sweet potato vines can become quite sprawling.

Starting sweet potato slips is an enjoyable and rewarding gardening project that allows you to grow your own nutritious sweet potatoes from a single tuber.
