Growing Sweet Potatoes in Containers: A Beginner’s Guide
Hey there, fellow gardening enthusiasts! I’m so excited to share one of my favorite DIY gardening projects with you: growing sweet potatoes in containers! It’s surprisingly easy, even if you don’t have a huge backyard. Plus, nothing beats the taste of homegrown sweet potatoes. Let’s dive in!
Choosing the Right Sweet Potato Variety
Before we get our hands dirty, let’s talk about sweet potato varieties. Not all sweet potatoes are created equal, especially when it comes to container gardening. Here’s what I’ve learned:
* Bush Varieties: These are your best bet for containers. They’re more compact and don’t produce as many sprawling vines as other types. Look for varieties like ‘Bush Porto Rico’ or ‘Georgia Jet.’
* Vining Varieties: While you *can* grow vining varieties in containers, you’ll need a much larger container and a trellis or support system. If you’re feeling ambitious, go for it! Just be prepared for some serious vine management.
* Consider Your Climate: Sweet potatoes love warm weather. Choose a variety that’s well-suited to your local climate and growing season.
Gathering Your Supplies
Okay, now for the fun part: gathering our supplies! Here’s what you’ll need:
* A Large Container: This is crucial! Sweet potatoes need plenty of room to grow. I recommend a container that’s at least 20 gallons in size and 18 inches deep. The bigger, the better, really.
* Well-Draining Potting Mix: Don’t use garden soil! It’s too heavy and compacts easily, which can hinder sweet potato growth. Opt for a high-quality potting mix that drains well.
* Sweet Potato “Slips”: These are sprouts that grow from a sweet potato. You can buy them online or at your local garden center, or you can even grow your own (more on that later!).
* Water: Obvious, but essential!
* Fertilizer: A balanced fertilizer (like 10-10-10) or a fertilizer specifically formulated for root vegetables will give your sweet potatoes a boost.
* Optional: Mulch (like straw or wood chips) to help retain moisture and suppress weeds.
Growing Your Own Sweet Potato Slips (Optional but Recommended!)
Growing your own slips is a rewarding experience and saves you money! Here’s how I do it:
1. Choose a Healthy Sweet Potato: Select an organic sweet potato from the grocery store or farmer’s market. Make sure it’s firm and free from blemishes.
2. Prepare the Sweet Potato: There are two ways to do this:
* Water Method: Suspend the sweet potato in a jar or glass of water, with the bottom half submerged. You can use toothpicks to hold it in place.
* Soil Method: Bury the sweet potato horizontally in a container filled with moist potting mix, leaving the top exposed.
3. Provide Warmth and Light: Place the jar or container in a warm, sunny location.
4. Wait Patiently: It can take several weeks for slips to emerge. Keep the water level consistent (for the water method) and the soil moist (for the soil method).
5. Harvest the Slips: Once the slips are 6-8 inches long, gently twist them off the sweet potato.
6. Root the Slips: Place the slips in a glass of water, with the bottom inch or two submerged. They should develop roots within a few days.
Planting Your Sweet Potato Slips
Alright, now for the main event: planting those slips!
1. Prepare the Container: Fill your container with potting mix, leaving a few inches of space at the top.
2. Water the Soil: Thoroughly water the potting mix until it’s evenly moist.
3. Plant the Slips: Dig small holes in the soil, about 4-6 inches apart. Gently place the rooted slips in the holes, burying the roots and the bottom part of the stem.
4. Water Again: Water the newly planted slips to help them settle in.
5. Mulch (Optional): Add a layer of mulch around the base of the plants to help retain moisture and suppress weeds.
Caring for Your Sweet Potato Plants
Now that your sweet potato plants are in their new home, it’s time to give them some TLC!
1. Watering: Sweet potatoes need consistent moisture, especially during hot weather. Water deeply whenever the top inch of soil feels dry to the touch. Avoid overwatering, as this can lead to root rot.
2. Fertilizing: Fertilize your sweet potato plants every 2-3 weeks with a balanced fertilizer or a fertilizer specifically formulated for root vegetables. Follow the instructions on the fertilizer package.
3. Sunlight: Sweet potatoes need at least 6-8 hours of sunlight per day. Place your container in a sunny location.
4. Vine Management: If you’re growing a vining variety, you’ll need to provide a trellis or support system for the vines to climb. You can also prune the vines to keep them from getting too unruly.
5. Pest Control: Keep an eye out for pests like aphids, flea beetles, and sweet potato weevils. Treat infestations promptly with insecticidal soap or neem oil.
6. Weed Control: Remove any weeds that pop up in the container to prevent them from competing with your sweet potato plants for nutrients and water.
Harvesting Your Sweet Potatoes
The moment we’ve all been waiting for: harvest time!
1. Timing: Sweet potatoes typically take 90-120 days to mature. You’ll know they’re ready to harvest when the leaves start to turn yellow and the vines begin to die back.
2. Careful Digging: Gently dig around the base of the plant, being careful not to damage the sweet potatoes.
3. Lifting the Potatoes: Once you’ve loosened the soil, carefully lift the sweet potatoes out of the container.
4. Curing: Curing is essential for developing the sweet flavor and improving the storage life of your sweet potatoes. To cure them, place them 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. Storing: After curing, store your sweet potatoes in a cool, dry, and dark place (55-60°F). They should last for several months.
Troubleshooting
Even with the best care, you might encounter some challenges along the way. Here are a few common problems and how to address them:
* Yellowing Leaves: This could be a sign of nutrient deficiency, overwatering, or pest infestation. Check the soil moisture, fertilize if necessary, and inspect the plants for pests.
* Slow Growth: This could be due to insufficient sunlight, poor soil, or cool temperatures. Make sure your plants are getting enough sunlight, use a high-quality potting mix, and wait for warmer weather.
* Root Rot: This is caused by overwatering. Make sure your container has good drainage and avoid watering too frequently.
* Pest Infestations: Treat infestations promptly with insecticidal soap or neem oil.
Tips for Success
Here are a few extra tips to help you grow the best sweet potatoes possible:
* Choose the Right Container: A large container is essential for sweet potato growth.
* Use Well-Draining Potting Mix: Avoid using garden soil, as it’s too heavy and compacts easily.
* Provide Plenty of Sunlight: Sweet potatoes need at least 6-8 hours of sunlight per day.
* Water Consistently: Keep the soil evenly moist, but avoid overwatering.
* Fertilize Regularly: Fertilize your sweet potato plants every 2-3 weeks.
* Cure Your Sweet Potatoes: Curing is essential for developing the sweet flavor and improving the storage life.
* Be Patient: Sweet potatoes take time to mature, so don’t get discouraged if you don’t see results right away.

Frequently Asked Questions
What size container do I need for growing sweet potatoes?
This is a crucial question! Sweet potatoes need ample space to develop their tubers. A minimum of 10 gallons per plant is recommended, but larger is always better. Aim for containers that are at least 12 inches deep and 18 inches in diameter. Half whiskey barrels or large plastic storage tubs work well. Remember, the bigger the container, the more sweet potatoes you’ll likely harvest. Insufficient space will result in smaller, fewer tubers.
What type of soil is best for container sweet potato growing?
Sweet potatoes thrive in well-draining, loose soil that is rich in organic matter. A mix of equal parts compost, potting soil, and perlite or vermiculite is ideal. Avoid heavy clay soils, as they can become waterlogged and hinder tuber development. The soil pH should be slightly acidic, around 6.0 to 6.5. You can amend your soil with sulfur to lower the pH if necessary. Regularly adding compost throughout the growing season will also help maintain soil fertility.
How often should I water my container sweet potatoes?
Watering frequency depends on the weather and the size of your container. Generally, you should water deeply whenever the top inch of soil feels dry to the touch. Avoid overwatering, as this can lead to root rot. During hot, dry periods, you may need to water daily. Ensure your containers have adequate drainage holes to prevent water from pooling at the bottom. Mulching around the base of the plants can help retain moisture and reduce the need for frequent watering.
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. Choose a location for your containers that receives ample sunlight throughout the growing season. If you live in a particularly hot climate, some afternoon shade may be beneficial to prevent the plants from overheating. Insufficient sunlight will result in leggy growth and reduced tuber production.
When is the best time to plant sweet potato slips in containers?
The best time to plant sweet potato slips is after the last frost, when the soil has warmed up to at least 65 degrees Fahrenheit. In most regions, this is typically in late spring or early summer. Planting too early can expose the slips to cold temperatures, which can stunt their growth or even kill them. You can purchase sweet potato slips from a nursery or start your own by sprouting sweet potatoes in water.
How do I fertilize my container sweet potatoes?
Sweet potatoes are heavy feeders and benefit from regular fertilization. Use a balanced fertilizer with an NPK ratio of 10-10-10 or 5-10-10. Apply the fertilizer according to the package instructions, typically every 2-3 weeks. Avoid over-fertilizing with nitrogen, as this can promote excessive foliage growth at the expense of tuber development. You can also supplement with organic fertilizers like compost tea or fish emulsion.
How do I know when my sweet potatoes are ready to harvest?
Sweet potatoes are typically ready to harvest about 90-120 days after planting. The foliage will start to turn yellow and die back, indicating that the tubers are mature. You can also gently dig around the base of the plant to check the size of the tubers. Harvest before the first frost, as frost can damage the tubers. Carefully dig up the sweet potatoes, being careful not to damage them.
Can I grow sweet potatoes in containers indoors?
While it’s possible to grow sweet potatoes indoors, it’s challenging to provide them with the necessary sunlight and space. They require a very sunny location, ideally a south-facing window, and may still need supplemental lighting. Indoor-grown sweet potatoes may not produce as many tubers as those grown outdoors. However, you can still enjoy the attractive foliage and even harvest the leaves for salads or stir-fries.
What are some common pests and diseases that affect container sweet potatoes?
Common pests that can affect sweet potatoes include aphids, flea beetles, and sweet potato weevils. Diseases include fungal diseases like stem rot and root rot. Regularly inspect your plants for signs of pests or diseases and take appropriate action. Organic pest control methods, such as insecticidal soap or neem oil, can be effective. Ensure good air circulation and avoid overwatering to prevent fungal diseases.
Can I reuse the soil from my container sweet potatoes?
Yes, you can reuse the soil from your container sweet potatoes, but it’s important to amend it with fresh compost and fertilizer before replanting. Sweet potatoes deplete the soil of nutrients, so replenishing them is essential. You can also sterilize the soil by baking it in the oven or solarizing it to kill any potential pests or diseases. Consider rotating your crops each year to prevent soilborne problems.
