Planting a whole sweet potato that has sprouted can be a great way to start a new crop, but it’s essential to do it correctly to ensure success. Sweet potatoes are a popular root vegetable that can be grown in many different climates and soil types. They are relatively easy to care for and can be harvested in as little as 100 days. In this article, we will explore the ins and outs of planting a whole sweet potato that has sprouted, including the benefits, potential drawbacks, and tips for success.
Understanding Sweet Potato Sprouts
Before we dive into the details of planting a whole sweet potato that has sprouted, it’s essential to understand what these sprouts are and how they form. Sweet potato sprouts, also known as slips, are the green shoots that grow from the “eyes” of a sweet potato. These eyes are actually the nodes where the sweet potato stem meets the root, and they contain dormant buds that can grow into new plants. When a sweet potato is exposed to light, warmth, and moisture, the buds in the eyes begin to sprout, producing new green growth.
The Benefits of Planting Sweet Potato Sprouts
Planting sweet potato sprouts can be a great way to start a new crop, and there are several benefits to using this method. One of the main advantages is that it allows you to reproduce your favorite variety of sweet potato, which can be difficult to find in stores or through other seed sources. Additionally, planting sweet potato sprouts can be a cost-effective way to start a new crop, as you can use sweet potatoes that you already have on hand. Finally, sweet potato sprouts can be ready to harvest in as little as 100 days, making them a great choice for gardeners who want a quick turnaround.
Potential Drawbacks of Planting Sweet Potato Sprouts
While planting sweet potato sprouts can be a great way to start a new crop, there are also some potential drawbacks to consider. One of the main risks is that the new plants may be more susceptible to disease, as they can inherit any diseases that were present in the parent sweet potato. Additionally, sweet potato sprouts can be more vulnerable to pests, such as aphids and whiteflies, which can spread disease and damage the plants. Finally, sweet potato sprouts may not produce tubers that are as large or flavorful as those produced by plants started from seed or seedlings.
Preparing the Sweet Potato for Planting
If you’ve decided to plant a whole sweet potato that has sprouted, there are a few steps you’ll need to take to prepare it for planting. First, make sure the sweet potato is healthy and free of disease, as any diseases present in the parent sweet potato can be passed on to the new plants. Next, cut the sweet potato into sections, making sure each section has at least one eye or sprout. Allow the cut sections to dry for a day or two to form a callus over the cut area, which will help prevent rot and disease.
Starting the Slips Indoors
Once the sweet potato sections have dried, you can start them indoors in a pot or tray filled with a well-draining seed starting mix. Make sure the soil is warm, around 75-85°F (24-29°C), as sweet potatoes prefer warm temperatures to grow. Water the soil gently but thoroughly, and keep it consistently moist but not waterlogged. It can take 1-2 weeks for the slips to develop roots and grow into small plants.
Transplanting the Slips Outdoors
Once the slips have developed roots and are around 6-8 inches (15-20 cm) tall, they can be transplanted outdoors into a garden bed. Choose a location that receives full sun and has well-draining soil, as sweet potatoes prefer these conditions to grow. Space the slips around 12-18 inches (30-45 cm) apart, and water them thoroughly after transplanting. Keep the soil consistently moist but not waterlogged, and provide support for the plants as they grow.
Tips for Success
To ensure success when planting a whole sweet potato that has sprouted, follow these tips:
- Choose a variety of sweet potato that is well-suited to your climate and soil type, as some varieties may perform better in certain conditions.
- Make sure the soil is warm and well-draining, as sweet potatoes prefer these conditions to grow.

Can I Plant a Whole Sweet Potato That Has Sprouted?
Planting a whole sweet potato that has sprouted can be a bit tricky, and it’s essential to understand the process before proceeding. Sweet potatoes are typically grown from slips, which are small pieces of tuber that have at least one “eye” each. These slips are often obtained from a nursery or created by allowing a sweet potato to sprout and then cutting it into sections. When you plant a whole sweet potato, the chances of it rotting before it can produce viable roots and shoots are higher because the large tuber may not get enough oxygen and may be more susceptible to fungal diseases.
However, if you still want to try planting a whole sweet potato that has sprouted, make sure it’s healthy and disease-free. Cut the sweet potato into sections, ensuring each section has at least one sprout. Let these sections dry for a day or two to form a callus over the cut area, which will help prevent rot. Then, plant them in well-draining soil with the sprouts facing upwards. Keep the soil moist but not waterlogged, and provide adequate sunlight. It might take some trial and error, but with the right conditions, you might be able to successfully grow new sweet potato plants from a whole sprouted tuber.
How Do I Prepare a Sweet Potato for Planting?
To prepare a sweet potato for planting, you first need to induce it to sprout. This can be done by placing the sweet potato in a light, cool, dry place. Once it has developed several strong sprouts, you can cut the sweet potato into sections, making sure each section has at least one sprout or “eye.” It’s crucial that each section has an eye because this is where the new plant will grow from. After cutting the sweet potato, allow the cut surfaces to dry for a day or two. This drying process helps form a callus over the wounds, reducing the risk of the section rotting once it’s planted.
After the sections have dried, they are ready to be planted. Plant them in a container or directly in the ground in a well-draining soil mix, making sure the soil is moist but not waterlogged. The sprouts should be facing upwards towards the sunlight. Keep the soil consistently moist during the first few weeks after planting. With proper care and the right conditions, these slips will grow into healthy sweet potato plants, ready to produce their own tubers in a few months. It’s also important to choose a variety of sweet potato that does well in your climate and has the desired characteristics for eating or storing.
What Are the Benefits of Growing Sweet Potatoes from Slips?
Growing sweet potatoes from slips has several benefits. One of the main advantages is that it allows for more control over the health and quality of the new plants. By selecting healthy, disease-free sweet potatoes to create slips from, you reduce the risk of introducing diseases into your garden. Additionally, using slips can increase the uniformity of the plants, as they all come from the same parent material. This can lead to a more consistent harvest in terms of size, flavor, and texture. Another benefit is that slips can give your sweet potatoes a head start on the growing season, as they are already several weeks ahead of seedlings that might be started from true seed.
When growing from slips, the time to harvest is generally shorter compared to starting from true seed, which can take a full season or more to produce viable tubers. This is because slips are essentially parts of a mature sweet potato that have been stimulated to grow new roots and shoots, skipping the initial seedling stage. With the right conditions and care, slips can produce harvestable sweet potatoes in as little as 3 to 4 months. This makes growing from slips a preferred method for many gardeners who want a quick turnaround and a high yield of quality sweet potatoes.
How Often Should I Water My Sweet Potato Plants?
The frequency of watering sweet potato plants depends on several factors, including the climate, soil type, and stage of growth. Generally, sweet potato plants prefer well-draining soil and consistent moisture, especially when they’re producing tubers. It’s essential to keep the soil moist but not waterlogged, as excessive moisture can lead to rot and other problems. During hot or dry weather, you may need to water more frequently to keep the soil consistently moist. However, in cooler or more humid conditions, less frequent watering might be sufficient.
As the plants grow, their water needs may change. During the first few weeks after planting, the soil should be kept moist to encourage root development. As the plants mature and start to produce tubers, they may require more water, especially if the weather is dry. It’s also important to avoid getting water on the leaves to prevent fungal diseases, instead aiming the water at the base of the plants. Monitoring the soil moisture by feel or using a moisture meter can help you determine the best watering schedule for your sweet potato plants.
Can I Grow Sweet Potatoes in Containers?
Yes, it’s absolutely possible to grow sweet potatoes in containers. In fact, container gardening can be a great way to produce sweet potatoes, especially in areas with limited garden space or poor soil. When growing sweet potatoes in containers, choose a container that is at least 12 inches deep to allow for good root development. The container should also have drainage holes to prevent waterlogging. Fill the container with a well-draining potting mix, and plant the sweet potato slips about 2-4 inches deep, with the sprouts facing upwards towards the sunlight.
Container-grown sweet potatoes require similar care to those grown in the ground, including full sun, consistent moisture, and fertilization. However, they may need more frequent watering due to the limited soil volume. It’s also important to provide support for the vines as they spread, which can be done using a trellis or other form of support. With proper care, container-grown sweet potatoes can thrive and produce a bountiful harvest. Just be aware that the yield might be smaller compared to plants grown in the ground, due to the limited root space. Still, growing sweet potatoes in containers can be a rewarding and space-efficient way to enjoy these delicious tubers.
How Long Does It Take for Sweet Potatoes to Mature?
The time it takes for sweet potatoes to mature can vary significantly depending on the variety, growing conditions, and how they are being grown. Generally, sweet potatoes are ready to harvest about 3 to 4 months after planting the slips. Some varieties mature more quickly, in as little as 100 days, while others may take up to 120 days or more. The maturity date is usually indicated on the package if you’re buying slips or seed from a nursery. It’s also important to keep in mind that sweet potatoes continue to grow and mature even after they’re harvested, a process that can be enhanced by curing them properly after harvest.
It’s crucial to wait for the right time to harvest to ensure the sweet potatoes are at their best flavor and texture. If harvested too early, they may not be as sweet or may be more susceptible to bruising. A common method to check for maturity is to wait for the vines to start yellowing and dying back, which is a natural sign that the tubers are mature. Gently digging around the plants with a fork can also help you check for size and readiness without damaging the tubers. Always handle the sweet potatoes carefully during harvest to avoid bruising or damaging them, which can affect their quality and storage life.
