Growing Sweet Potatoes at Home: A Beginner’s Guide
Hey there, fellow gardening enthusiasts! I’m so excited to share my experience with growing sweet potatoes at home. It might seem daunting, but trust me, it’s incredibly rewarding and surprisingly easy once you get the hang of it. Plus, nothing beats the taste of homegrown sweet potatoes! This guide will walk you through every step, from sprouting slips to harvesting your delicious bounty.
Choosing Your Sweet Potato Variety
Before we dive in, let’s talk varieties. Sweet potatoes come in a range of colors, textures, and flavors. Some popular choices include:
* Beauregard: A classic orange-fleshed variety, known for its sweetness and reliability. This is what you’ll often find in grocery stores.
* Jewel: Another orange-fleshed option, slightly drier than Beauregard, but still delicious.
* Garnet: Deep red skin with orange flesh, very sweet and moist.
* Japanese (Muraski): Purple skin with white flesh, less sweet and more nutty flavor.
* Okinawan: Purple skin and purple flesh, also less sweet and nutty.
I personally love Beauregard for its consistent sweetness, but feel free to experiment and find your favorite!
Sprouting Sweet Potato Slips
Sweet potato slips are basically the sprouts that grow from a mature sweet potato. You can’t directly plant a sweet potato in the ground and expect it to grow. You need these slips! Here’s how to get them started:
1. Choose Your Sweet Potato: Select a healthy, organic sweet potato. Organic is important because non-organic potatoes are often treated to prevent sprouting. I usually pick one that’s medium-sized and free of blemishes.
2. Prepare Your Sprouting Container: You have a couple of options here. You can use a glass jar, a plastic container, or even a dedicated sprouting tray. I prefer a glass jar so I can easily monitor the water level and root growth.
3. Insert Toothpicks (Optional): This step is for jar sprouting. Insert 3-4 toothpicks around the middle of the sweet potato. These will act as supports, allowing the bottom half of the potato to sit in the water while the top half remains dry.
4. Submerge the Bottom Half: Fill your container with water, leaving about an inch of space at the top. Place the sweet potato in the container, supported by the toothpicks (if using), so that the bottom half is submerged. If you’re using a container without toothpicks, you can bury the sweet potato halfway in moist potting mix or vermiculite.
5. Find a Warm, Sunny Spot: Place your sprouting setup in a warm location with plenty of sunlight. A windowsill is ideal. The ideal temperature is between 75-85°F (24-29°C).
6. Change the Water Regularly: Refresh the water every 2-3 days to prevent mold and bacteria growth. This is crucial for healthy slip development.
7. Wait Patiently: This is the hardest part! It can take anywhere from 4-8 weeks for slips to emerge. You’ll start to see small sprouts forming on the sweet potato.
8. Harvesting the Slips: Once the slips are about 6-8 inches long, they’re ready to be harvested. Gently twist or cut them off the sweet potato. I prefer twisting, as it seems to cause less damage to the mother potato.
9. Rooting the Slips: Place the harvested slips in a glass of water, ensuring that the bottom inch or two is submerged. Change the water daily. Within a few days, you’ll see roots starting to form.
Preparing Your Garden Bed
Sweet potatoes need plenty of space and well-drained soil. Here’s how to get your garden bed ready:
1. Choose a Sunny Location: Sweet potatoes need at least 6-8 hours of direct sunlight per day. Pick a spot in your garden that gets plenty of sunshine.
2. Prepare the Soil: Sweet potatoes thrive in loose, well-drained soil. Amend your soil with compost or well-rotted manure to improve drainage and fertility. Avoid heavy clay soils, as they can lead to misshapen potatoes. I like to add a generous amount of compost to my sweet potato bed.
3. Create Ridges or Mounds: Sweet potatoes grow best in raised beds or mounds. This helps with drainage and allows the potatoes to expand. Create ridges that are about 8-10 inches high and 12 inches wide. Space the ridges about 3 feet apart.
4. Test Your Soil (Optional): A soil test can help you determine the pH level and nutrient content of your soil. Sweet potatoes prefer a slightly acidic soil pH of 5.5-6.5. You can adjust the pH by adding lime (to raise it) or sulfur (to lower it).
Planting Your Sweet Potato Slips
Now for the fun part – planting!
1. Harden Off the Slips: Before planting, it’s important to harden off the slips. This means gradually acclimating them to outdoor conditions. Place the slips in a sheltered location outdoors for a few hours each day, gradually increasing the amount of time they spend outside. Do this for about a week before planting.
2. Plant After the Last Frost: Sweet potatoes are sensitive to frost, so wait until after the last frost date in your area to plant them. The soil temperature should be at least 65°F (18°C).
3. Plant the Slips: Dig a small hole in the top of each ridge or mound. Plant the slips about 4-6 inches deep, spacing them about 12 inches apart. Make sure to bury the roots and at least one node (the point where leaves emerge).
4. Water Thoroughly: After planting, water the slips thoroughly. This will help them establish roots.
5. Mulch (Optional): Mulching around the plants can help retain moisture, suppress weeds, and regulate soil temperature. I like to use straw or hay as mulch.
Caring for Your Sweet Potato Plants
Once your sweet potato plants are in the ground, they’ll need some TLC to thrive.
1. Water Regularly: Sweet potatoes need consistent moisture, especially during the first few weeks after planting. Water deeply whenever the soil feels dry to the touch.
2. Weed Regularly: Keep the garden bed free of weeds, as they can compete with the sweet potato plants for nutrients and water.
3. Fertilize (Optional): Sweet potatoes don’t need a lot of fertilizer, but a light feeding of a balanced fertilizer can help boost growth. Avoid fertilizers that are high in nitrogen, as this can promote leafy growth at the expense of tuber development. I usually use a fertilizer with a ratio of 5-10-10.
4. Control Pests and Diseases: Sweet potatoes are generally pest-resistant, but they can be susceptible to certain pests and diseases, such as sweet potato weevils and fungal diseases. Inspect your plants regularly and take action if you notice any problems. Organic pest control methods, such as neem oil, can be effective.
5. Vine Training (Optional): Sweet potato vines can spread quite a bit, so you may want to train them to grow in a specific direction. You can use stakes or trellises to support the vines.
Harvesting Your Sweet Potatoes
The moment you’ve been waiting for! Harvesting sweet potatoes is a rewarding experience.
1. Harvest Before the First Frost: Sweet potatoes should be harvested before the first frost in your area. Frost can damage the tubers and make them susceptible to rot.
2. Loosen the Soil: Use a garden fork or shovel to carefully loosen the soil around the plants. Be careful not to damage the potatoes.
3. Gently Dig Up the Potatoes: Gently lift the plants from the ground, being careful not to bruise or cut the potatoes.
4. Cure the Potatoes: Curing is an important step that helps to improve the flavor and storage life of sweet potatoes. To cure them, place the potatoes in a warm, humid location (80-85°F and 85-90% humidity) for 7-10 days. A greenhouse or a warm, sunny room with a humidifier works well.
5. Store the Potatoes: After curing, store the sweet potatoes in a cool, dry, and dark place (55-60°F). They should keep for several months.
Troubleshooting
Even with the best planning, sometimes things don’t go as expected. Here are a few common problems and how to address them:
* Slips Not Sprouting: Make sure the sweet potato is organic and that the water is being changed regularly. The temperature may also be too low.
* Yellowing Leaves: This could be a sign of nutrient deficiency or overwatering. Check the soil moisture and consider adding a balanced fertilizer.

Q: How often should I water sweet potatoes?
A: Sweet potatoes need consistent moisture, especially during the initial stages of growth after transplanting the slips. Water deeply and regularly, aiming to keep the soil consistently moist but not waterlogged. Once the plants are established, you can reduce watering frequency, allowing the soil to dry out slightly between waterings. Avoid overwatering, as this can lead to root rot.
Q: Do sweet potatoes need fertilizer?
A: While sweet potatoes are not heavy feeders, they benefit from a balanced fertilizer application. Before planting, amend the soil with compost or well-rotted manure to provide a slow-release source of nutrients. You can also apply a fertilizer with a low nitrogen content (e.g., 5-10-10) a few weeks after transplanting. Avoid over-fertilizing with nitrogen, as this can promote excessive foliage growth at the expense of tuber development.
Q: How do I harvest sweet potatoes?
A: Harvest sweet potatoes when the foliage starts to yellow and die back, typically in the fall before the first frost. Use a garden fork or shovel to carefully dig around the plants, being careful not to damage the tubers. Gently lift the plants from the soil, and brush off any excess dirt. Cure the sweet potatoes by placing them in a warm, humid location (80-85°F and 85-90% humidity) for 7-10 days. This process allows the skins to harden and the starches to convert to sugars, resulting in a sweeter flavor and improved storage life.
Q: How do I store sweet potatoes?
A: After curing, store sweet potatoes in a cool, dry, and well-ventilated location (55-60°F). Avoid storing them in the refrigerator, as this can cause them to develop a hard core and lose their flavor. Properly cured and stored sweet potatoes can last for several months.
Q: What are some common pests and diseases that affect sweet potatoes?
A: Common pests that can affect sweet potatoes include sweet potato weevils, flea beetles, and wireworms. Diseases include stem rot, black rot, and scurf. Practice crop rotation, use disease-resistant varieties, and maintain good soil drainage to minimize the risk of pest and disease problems. Inspect your plants regularly for signs of infestation or disease, and take appropriate action if necessary. Organic pest control methods, such as neem oil or insecticidal soap, can be effective for managing many common pests.
Q: Can I grow sweet potatoes in containers?
A: Yes, you can successfully grow sweet potatoes in containers, especially if you have limited space. Choose a large container (at least 20 gallons) with good drainage holes. Fill the container with a well-draining potting mix amended with compost. Plant the slips in the container, and provide them with plenty of sunlight and water. Container-grown sweet potatoes may not produce as many tubers as those grown in the ground, but you can still enjoy a decent harvest.
Q: My sweet potato vines are growing vigorously, but I’m not getting many sweet potatoes. What could be the problem?
A: Several factors could contribute to this issue. Over-fertilizing with nitrogen can promote excessive vine growth at the expense of tuber development. Make sure you are using a fertilizer with a low nitrogen content. Also, ensure that your sweet potatoes are receiving enough sunlight (at least 6-8 hours per day). Insufficient sunlight can also lead to poor tuber formation. Finally, check the soil drainage. Poorly drained soil can inhibit root growth and reduce yields.
