Growing Sweet Potatoes: A DIY Guide to Bountiful Harvests
Hey there, fellow gardening enthusiasts! I’m so excited to share my experience with growing sweet potatoes. It’s a rewarding process, and nothing beats the taste of homegrown sweet potatoes. This guide will walk you through every step, from preparing your slips to harvesting your delicious bounty. Let’s get started!
Preparing Your Sweet Potato Slips
Sweet potatoes don’t grow directly from seeds. Instead, we use “slips,” which are sprouts that grow from the sweet potato itself. You can buy slips, but it’s much more fun (and cheaper!) to grow your own.
What you’ll need:
* A healthy sweet potato (organic is best to avoid any growth inhibitors)
* A glass jar or container
* Toothpicks
* Water
Step-by-step instructions:
1. Choose your sweet potato: Select a firm, healthy sweet potato. Avoid any with soft spots or blemishes. I usually pick one from my last harvest, ensuring it’s a variety I love.
2. Prepare the sweet potato: Thoroughly wash the sweet potato to remove any dirt.
3. Insert toothpicks: Insert 3-4 toothpicks around the middle of the sweet potato. These will act as supports to suspend the potato in the jar.
4. Suspend the sweet potato: Fill the jar with water, ensuring the bottom half of the sweet potato is submerged. The toothpicks should rest on the rim of the jar, holding the potato in place.
5. Find a sunny spot: Place the jar in a warm, sunny location. A windowsill is perfect.
6. Maintain the water level: Check the water level regularly and add more as needed to keep the bottom of the sweet potato submerged.
7. Wait for sprouts: Be patient! It can take several weeks for sprouts (slips) to emerge from the sweet potato. You’ll start to see small roots growing into the water and green shoots appearing on the potato.
8. Separate the slips: Once the slips are about 6-8 inches long, they’re ready to be separated. Gently twist or cut them off the sweet potato. I prefer twisting, as it seems to cause less damage.
9. Root the slips in water: Place the slips in a glass of water, ensuring the bottom inch or two is submerged. This will encourage root development.
10. Wait for roots: In a few days to a week, you’ll see roots forming. Once the roots are about an inch long, the slips are ready to be planted.
Preparing the Garden Bed
Sweet potatoes love warm weather and well-drained soil. Preparing your garden bed properly is crucial for a successful harvest.
What you’ll need:
* Garden fork or tiller
* Compost or well-rotted manure
* Raised beds (optional, but recommended)
* Dark-colored plastic mulch (optional, but helpful in cooler climates)
Step-by-step instructions:
1. Choose a sunny location: Select a spot in your garden that receives at least 6-8 hours of direct sunlight per day.
2. Prepare the soil: Sweet potatoes prefer loose, well-drained soil. If your soil is heavy clay, amend it with plenty of compost or well-rotted manure. This will improve drainage and provide essential nutrients.
3. Till or dig the soil: Use a garden fork or tiller to loosen the soil to a depth of at least 12 inches. This will allow the sweet potato roots to grow easily.
4. Create raised beds (optional): Raised beds are ideal for growing sweet potatoes, especially in areas with heavy clay soil or poor drainage. They also warm up faster in the spring. I always use raised beds for my sweet potatoes.
5. Amend the soil with compost: Incorporate a generous amount of compost or well-rotted manure into the soil. This will provide the sweet potatoes with the nutrients they need to thrive.
6. Consider plastic mulch (optional): In cooler climates, dark-colored plastic mulch can help warm the soil and suppress weeds. Lay the plastic mulch over the prepared bed and secure it with soil or rocks.
Planting Your Sweet Potato Slips
Now comes the fun part – planting your slips! This is where all your hard work starts to pay off.
What you’ll need:
* Your rooted sweet potato slips
* Watering can or hose
* Trowel or small shovel
Step-by-step instructions:
1. Wait for warm weather: Sweet potatoes are very sensitive to frost. Wait until all danger of frost has passed and the soil has warmed up to at least 60°F (15°C) before planting. I usually plant mine in late May or early June.
2. Prepare the planting holes: Space the slips about 12-18 inches apart in rows that are 3-4 feet apart. Dig small holes that are deep enough to accommodate the roots of the slips.
3. Plant the slips: Gently remove the slips from the water and carefully place them in the planting holes. Make sure the roots are spread out and cover them with soil. Leave the top leaves exposed.
4. Water thoroughly: Water the newly planted slips thoroughly to help them establish.
5. Protect from pests (optional): If you have problems with pests like flea beetles, you can cover the newly planted slips with row covers.
Caring for Your Sweet Potato Plants
Sweet potatoes are relatively low-maintenance, but they do need some care to thrive.
What you’ll need:
* Watering can or hose
* Weeding tools
* Organic fertilizer (optional)
Step-by-step instructions:
1. Water regularly: Water the sweet potato plants regularly, especially during dry periods. They need about 1 inch of water per week.
2. Weed regularly: Keep the garden bed free of weeds, as they can compete with the sweet potatoes for nutrients and water.
3. Fertilize (optional): If your soil is poor, you can fertilize the sweet potato plants with an organic fertilizer. Follow the instructions on the fertilizer package. I usually use a balanced fertilizer a few weeks after planting.
4. Control pests and diseases: Monitor the plants for pests and diseases. Common pests include flea beetles and sweet potato weevils. Common diseases include fungal diseases. Treat any problems promptly with appropriate organic controls.
5. Avoid over-watering: While sweet potatoes need regular watering, avoid over-watering, as this can lead to root rot.
Harvesting Your Sweet Potatoes
The moment you’ve been waiting for! Harvesting sweet potatoes is a rewarding experience.
What you’ll need:
* Garden fork
* Gloves
* Sharp knife or pruning shears
Step-by-step instructions:
1. Know when to harvest: Sweet potatoes are typically ready to harvest about 90-120 days after planting. The leaves will start to turn yellow and the vines will begin to die back. I usually harvest mine in late September or early October, before the first frost.
2. Choose a dry day: Harvest your sweet potatoes on a dry day to prevent them from rotting.
3. Loosen the soil: Use a garden fork to carefully loosen the soil around the sweet potato plants. Be careful not to damage the sweet potatoes.
4. Lift the sweet potatoes: Gently lift the sweet potato plants from the soil, being careful not to break the sweet potatoes.
5. Cut the vines: Use a sharp knife or pruning shears to cut the vines from the sweet potatoes.
6. Cure the sweet potatoes: Curing is essential for developing the sweet flavor and improving the storage life of sweet potatoes. Place the sweet potatoes in a warm, humid place (80-85°F and 85-90% humidity) for 7-10 days. A greenhouse or a warm, sunny room is ideal.
7. Store the sweet potatoes: After curing, store the sweet potatoes in a cool, dry, and dark place (55-60°F). They should keep for several months. I store mine in a cardboard box in my basement.
Tips for a Successful Harvest
* Don’t wash the sweet potatoes before curing: Washing can promote rot.
* Handle the sweet potatoes carefully: They bruise easily.
* Check the sweet potatoes regularly during storage: Remove any that show signs of rot.
* Enjoy your harvest! Sweet potatoes are delicious roasted, baked, mashed, or used in pies and other desserts.
Growing sweet potatoes is a fantastic experience that connects you with nature and provides you with a delicious and nutritious food source. I hope this guide has inspired you to give it a try. Happy gardening!

Frequently Asked Questions (FAQ)
What are sweet potato slips and where can I get them?
Sweet potato slips are sprouts that grow from a mature sweet potato. They are essentially baby sweet potato plants that are ready to be planted in the ground. You can grow your own slips by placing a sweet potato in water (partially submerged) or purchase them from a local nursery or online retailer specializing in vegetable starts. Growing your own is a cost-effective and rewarding option, allowing you to control the variety and quality of your slips. When buying, ensure the slips are healthy, with vibrant green leaves and strong stems. Avoid slips that are yellowed, wilted, or show signs of disease.
How much sunlight do sweet potatoes need?
Sweet potatoes are sun-loving plants and require at least 6-8 hours of direct sunlight per day to thrive. Insufficient sunlight can lead to stunted growth, reduced yields, and smaller tubers. Choose a planting location that receives ample sunlight throughout the day. If you’re growing sweet potatoes in containers, make sure to place them in a sunny spot on your patio or balcony. If you live in an area with intense afternoon sun, providing some afternoon shade can prevent the leaves from scorching.
What kind of soil is best for growing sweet potatoes?
Sweet potatoes prefer well-drained, sandy loam soil that is rich in organic matter. Heavy clay soil can hinder root development and lead to misshapen tubers. Before planting, amend your soil with compost, aged manure, or other organic materials to improve drainage and fertility. A slightly acidic soil pH of 6.0 to 6.5 is ideal. Avoid soils that are excessively high in nitrogen, as this can promote leafy growth at the expense of tuber development.
How often should I water my sweet potato plants?
Sweet potatoes need consistent moisture, especially during the first few weeks after planting. Water deeply and regularly, ensuring the soil remains moist but not waterlogged. Once the plants are established, you can reduce watering frequency, allowing the soil to dry out slightly between waterings. Avoid overhead watering, as this can increase the risk of fungal diseases. Instead, water at the base of the plants, using a soaker hose or drip irrigation system. During periods of drought or extreme heat, increase watering frequency to prevent the plants from wilting.
When is the best time to harvest sweet potatoes?
Sweet potatoes are typically ready to harvest about 90-120 days after planting, depending on the variety and growing conditions. A good indicator of maturity is when the leaves start to turn yellow and the vines begin to die back. Harvest before the first frost, as frost can damage the tubers and affect their storage life. To harvest, carefully dig around the plants with a garden fork, being careful not to damage the tubers. Gently lift the plants from the ground and brush off any excess soil.
How do I cure sweet potatoes after harvesting?
Curing is an essential step in preserving sweet potatoes and improving their flavor and sweetness. After harvesting, allow the sweet potatoes to dry in a warm, humid place (80-85°F and 85-90% humidity) for 7-10 days. This process allows the skins to harden and heal any minor cuts or bruises, preventing rot and extending their storage life. You can cure sweet potatoes in a well-ventilated shed, garage, or even a spare room, using a humidifier to maintain the desired humidity level. After curing, store the sweet potatoes in a cool, dry, and dark place (55-60°F) for several months.
Can I grow sweet potatoes in containers?
Yes, sweet potatoes can be successfully grown in containers, making them a great option for gardeners with limited space. Choose a large container that is at least 20 gallons in size and has good drainage holes. Fill the container with a well-draining potting mix that is rich in organic matter. Plant one or two sweet potato slips per container and provide them with plenty of sunlight and water. Container-grown sweet potatoes may require more frequent watering and fertilization than those grown in the ground.
What are some common pests and diseases that affect sweet potatoes?
Sweet potatoes are generally resistant to pests and diseases, but they can be susceptible to certain problems, such as sweet potato weevils, wireworms, and fungal diseases like fusarium wilt and scurf. To prevent pest and disease problems, practice good garden hygiene, such as removing weeds and debris from around the plants. Rotate your crops each year to prevent soilborne diseases from building up. If you notice any signs of pests or diseases, take action promptly by using organic pest control methods or fungicides.
How do I store sweet potatoes after curing?
After curing, store sweet potatoes in a cool, dry, and dark place with good ventilation. The ideal storage temperature is between 55-60°F (13-16°C). Avoid storing sweet potatoes in the refrigerator, as this can cause them to develop a hard core and lose their flavor. Store them in a single layer in a well-ventilated container, such as a cardboard box or a wire basket. Check the sweet potatoes periodically for signs of spoilage and remove any that are soft or rotten. Properly cured and stored sweet potatoes can last for several months.
Can I eat the sweet potato leaves?
Yes, sweet potato leaves are edible and nutritious! They are a good source of vitamins, minerals, and antioxidants. The leaves can be cooked and eaten like spinach or other leafy greens. Harvest young, tender leaves for the best flavor and texture. Avoid eating leaves from plants that have been treated with pesticides or herbicides. Sweet potato leaves can be added to salads, stir-fries, soups, and stews. They have a slightly sweet and nutty flavor.
