Did You Know?
1. Sweet potato slips can be started from either a whole sweet potato or from individual small sweet potatoes called “seed potatoes.”
2. Some sweet potato varieties produce more slips than others, with some plants yielding as few as 1 or 2 slips and others producing up to 50 slips.
3. Sweet potato slips are essentially vine cuttings that you can use to propagate the plant. They are small shoots that emerge from the surface of the sweet potato.
4. Sweet potato slips can be grown indoors in a warm, sunny location before transplanting them outdoors, which allows you to enjoy fresh sweet potatoes even in colder climates.
5. Although sweet potatoes are often associated with Thanksgiving and holiday dishes, they are actually a staple crop for many countries, particularly in Africa, Asia, and Latin America, where they provide a significant source of nutrition.
Planting Sweet Potato Slips: Timing And Preparation
Timing is crucial when it comes to planting sweet potato slips. Aim to plant them in the ground about three weeks after the last frost date in spring. This ensures that the soil has warmed up enough for the slips to thrive. If planted too early, the cold soil can stunt their growth.
Before planting, it’s important to prepare the soil. Sweet potatoes thrive in loose, well-drained soil. Ensure that the area has good drainage to prevent waterlogging. You can improve the soil’s drainage by adding sand or potting soil to the planting area.
To start, select a healthy sweet potato that will serve as the source of slips. Look for one that has no visible signs of disease or rot. Wash the sweet potato thoroughly to remove any dirt or chemical residue. Now, bury the lower half of the sweet potato in the container filled with soil or sand. Ensure that the container has a drainage hole to prevent water accumulation.

Growing And Developing Sweet Potato Slips
Once the sweet potato slips are planted, it will take about 6-8 weeks for them to develop fully. During this time, it’s essential to provide them with proper care and maintenance. Keep the soil moist but not soaking wet. Overwatering can lead to rot and disease, while underwatering can cause the slips to dry out and wither.
After about a month, you will start to see shoots sprouting from the tuberous root. These shoots will eventually develop into the slips. When the slips are around 4-6 inches tall, they are ready to be separated from the sweet potato and planted in the ground.
It’s important to note that a single sweet potato can usually produce 10 to 20 good slips. So, make sure to choose a healthy and robust sweet potato to maximize your slip yield.
- Plant the sweet potato slips and wait 6-8 weeks for full development.
- Provide proper care and maintenance, keeping the soil moist but not soaking wet.
- Look for shoots sprouting from the tuberous root after a month.
- When the slips reach 4-6 inches tall, separate them from the sweet potato and plant in the ground.
- Remember, a single sweet potato can produce 10 to 20 good slips, so choose a healthy one.
How To Choose And Prepare Sweet Potatoes For Slips
Choosing the right sweet potato is crucial for a successful harvest of slips. When selecting sweet potatoes, look for smooth skin that is free from blemishes or signs of decay. It is also important to check for firmness, as softer sweet potatoes may indicate rot or disease.
To prepare the sweet potatoes for slips, it is essential to wash them thoroughly to remove any dirt or chemicals. This step is important to ensure that the sweet potatoes are clean and free from any substances that could hinder slip development.
After cleaning the sweet potatoes, bury the lower half in a container with soil or sand. By doing this, you will encourage the development of slips from the submerged portion. Burying them in a container also allows for easy monitoring of their growth and ensures they receive proper care.
Watering And Maintenance Of Sweet Potato Slips
Proper watering and maintenance are crucial for the health and growth of sweet potato slips. While it’s important to keep the soil moist, avoid overwatering, as it can lead to rot and fungal diseases. To maintain adequate moisture levels, water the slips regularly, but ensure that the soil does not become waterlogged.
In addition to watering, it’s essential to provide the slips with proper nutrition. Sweet potatoes require a balanced and nutrient-rich soil to grow and develop well. Consider adding organic matter, such as compost or well-rotted manure, to enrich the soil.
To avoid weed competition, it’s recommended to mulch around the slips with clean straw. This will help to suppress weed growth and conserve soil moisture.
Regularly check for pests and diseases, and take prompt action if any are detected. Proper maintenance and care of sweet potato slips will ensure a healthy and successful harvest.

Harvesting Sweet Potatoes: Timing And Factors To Consider
It’s important to harvest sweet potatoes prior to any frost or freeze, regardless of your location. Unlike regular potatoes, sweet potatoes are not frost-tolerant and can be damaged by cold temperatures.
To determine the optimal time for harvesting sweet potatoes, keep an eye on the night temperatures. When they start to dip into the 40s to 30s, it’s a sign that it’s time to harvest. This will help you avoid any frost damage and ensure that the sweet potatoes have reached their maximum potential in terms of taste and size.
If you have a shorter growing season, the sweet potatoes may be smaller in size, but they will still have the same delicious taste as larger ones. Remember that the longer the plants stay in the ground, the larger and more abundant the harvest will be.
Tip: Harvest sweet potatoes before frost or freeze to avoid damage.
Steps for Harvesting Sweet Potatoes:
- Keep an eye on night temperatures.
- Harvest when temperatures start to dip into the 40s to 30s.
- This ensures optimal taste and size.
Note: Shorter growing seasons may result in smaller sweet potatoes, but the taste remains delicious. The longer sweet potatoes remain in the ground, the larger and more abundant the harvest becomes.
Frequently Asked Questions
How do you start a sweet potato vine?
To start a sweet potato vine, begin by placing a sweet potato into a jar and filling it with water, ensuring there is about a 1-inch gap between the water and the top of the jar. It is crucial to keep the sweet potato plant exposed to moderate to full sunlight in a room temperature environment of above 65 degrees. Regularly monitor the water levels and add more water as needed, creating an ideal setting for the sweet potato vine to thrive and grow.
What is the best soil for sweet potatoes?
The ideal soil for growing sweet potatoes is a well-drained, light sandy loam or silt loam. This type of soil provides the necessary conditions for sweet potatoes to thrive and produce high-quality roots. It allows for good water drainage, ensuring that the roots are not sitting in excess water which can lead to rotting. Additionally, this type of soil offers sufficient porosity and nutrient availability for the sweet potatoes to develop and grow properly.
What are the nodes in a sweet potato slip?
Nodes in a sweet potato slip are key structures that play a critical role in root development. Each node contains a range of 4 to 10 preformed roots, known as primordia, which have the inherent ability to develop into adventitious roots. These adventitious roots, together with the ones that emerge from callus tissue on the cut end of a sweet potato slip, form the complete root system of the sweet potato plant. Nodes essentially serve as the starting point for root growth and provide the foundation for a robust and efficient root system in sweet potato plants.
When should I start sweet potatoes?
To ensure successful growth, it is advisable to start planting sweet potatoes when the ground has thawed and the last spring frost has already occurred. However, in areas where the ground does not freeze during winter, it is recommended to begin planting approximately a month after the last recorded spring frost date. This timing allows for optimal conditions and gives the sweet potato plants a favorable start for healthy growth and development. By adhering to these guidelines, you can maximize the chances of a bountiful sweet potato harvest in your specific climate.
