Growing Sweet Potatoes Indoors: A Year-Round Harvest!
Hey there, fellow gardening enthusiasts! Ever dreamt of enjoying homegrown sweet potatoes even when Jack Frost is nipping at your nose? Well, dream no more! I’m going to walk you through a super fun and rewarding project: growing sweet potatoes indoors. It’s easier than you think, and the satisfaction of harvesting your own sweet potatoes in the dead of winter is just unbeatable.
Choosing Your Sweet Potato
First things first, you need a sweet potato! Not just any sweet potato will do, though. Look for one that’s organic and hasn’t been treated with sprout inhibitors. You want a healthy, firm sweet potato with no soft spots or blemishes. I usually grab one from my local farmer’s market, but a good quality organic sweet potato from the grocery store will work just fine.
Sprouting Your Sweet Potato (Creating Slips)
This is where the magic begins! We’re going to coax our sweet potato into producing “slips,” which are basically baby sweet potato plants.
What you’ll need:
* A healthy sweet potato
* A wide-mouthed jar or glass (like a mason jar)
* Toothpicks
* Water
Step-by-step instructions:
1. Prep the Sweet Potato: Give your sweet potato a good wash to remove any dirt.
2. Insert Toothpicks: Insert 3-4 toothpicks evenly spaced around the middle of the sweet potato. These will act as supports, allowing you to suspend the sweet potato in the jar.
3. Fill the Jar with Water: Fill your jar with water, leaving about an inch of space at the top.
4. Suspend the Sweet Potato: Carefully balance the sweet potato on the rim of the jar, using the toothpicks to hold it in place. The bottom half of the sweet potato should be submerged in the water.
5. Find a Sunny Spot: Place the jar in a warm, sunny location. A windowsill that gets plenty of sunlight is ideal.
6. Maintain Water Level: Keep an eye on the water level and replenish it as needed. The bottom of the sweet potato should always be submerged.
7. Wait Patiently: This is the hardest part! It can take several weeks for the sweet potato to start sprouting. Be patient, and you’ll soon see little roots emerging from the bottom and green shoots (slips) appearing on top.
8. Harvesting the Slips: Once the slips are about 6-8 inches long, it’s time to harvest them. Gently twist or cut them off the sweet potato. I prefer to cut them, leaving a small stub so more slips can grow.
9. Rooting the Slips: Place the slips in a glass of water, making sure the bottom inch or two is submerged. In a few days, they’ll start to develop their own roots. Change the water every couple of days to keep it fresh.
Planting Your Sweet Potato Slips
Now that you have rooted slips, it’s time to plant them in soil!
What you’ll need:
* Rooted sweet potato slips
* Large pots or containers (at least 10 gallons per plant)
* Well-draining potting mix (a mix of potting soil, compost, and perlite works well)
* Water
* Grow lights (optional, but highly recommended)
Step-by-step instructions:
1. Prepare Your Pots: Fill your pots with the well-draining potting mix, leaving a couple of inches of space at the top.
2. Plant the Slips: Gently dig a small hole in the soil for each slip. Carefully remove the slip from the water and plant it in the hole, burying the roots and the bottom part of the stem.
3. Water Thoroughly: Water the newly planted slips thoroughly, making sure the soil is evenly moist.
4. Provide Light: Place the pots in a sunny location or under grow lights. Sweet potatoes need at least 6-8 hours of sunlight per day to thrive. If you’re using grow lights, position them a few inches above the plants.
5. Maintain Moisture: Keep the soil consistently moist, but not waterlogged. Water when the top inch of soil feels dry to the touch.
6. Fertilize Regularly: Sweet potatoes are heavy feeders, so fertilize them regularly with a balanced fertilizer. Follow the instructions on the fertilizer packaging. I like to use a liquid fertilizer diluted to half strength every two weeks.
7. Provide Support (Optional): As the vines grow, they may need some support. You can use stakes, trellises, or even let them trail along the floor.
Caring for Your Indoor Sweet Potato Plants
Growing sweet potatoes indoors requires a bit of attention, but it’s totally worth it!
Here are some tips for keeping your plants happy and healthy:
* Temperature: Sweet potatoes prefer warm temperatures, ideally between 70-85°F (21-29°C).
* Humidity: They also like high humidity. If your indoor environment is dry, you can increase humidity by using a humidifier or placing the pots on trays filled with pebbles and water.
* Pest Control: Keep an eye out for pests like aphids, spider mites, and whiteflies. If you spot any pests, treat them with insecticidal soap or neem oil.
* Pruning: Prune the vines as needed to keep them from getting too unruly. You can also pinch off the tips of the vines to encourage bushier growth.
Harvesting Your Sweet Potatoes
This is the moment you’ve been waiting for! Harvesting your own homegrown sweet potatoes.
When to harvest:
* Sweet potatoes typically take about 90-120 days to mature. You’ll know they’re ready to harvest when the vines start to yellow and die back.
How to harvest:
1. Stop Watering: Stop watering the plants a week or two before harvest to allow the soil to dry out slightly.
2. Carefully Dig: Gently dig around the base of the plant, being careful not to damage the sweet potatoes.
3. Lift the Plant: Carefully lift the plant out of the pot, and you should see a cluster of sweet potatoes attached to the roots.
4. Cure the Sweet Potatoes: Curing is an important step that helps to improve the flavor and storage life of your sweet potatoes. To cure them, place them in a warm, humid place (80-85°F/27-29°C and 85-90% humidity) for about a week. You can use a greenhouse, a warm room with a humidifier, or even a plastic bag with a damp cloth.
5. Store Your Sweet Potatoes: After curing, store your sweet potatoes in a cool, dry place (55-60°F/13-16°C) with good ventilation. They should keep 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 fix them:
* Yellowing Leaves: This could be a sign of overwatering, underwatering, or nutrient deficiency. Check the soil moisture and adjust your watering schedule accordingly. Fertilize regularly with a balanced fertilizer.
* Leggy Growth: This usually indicates insufficient light. Move your plants to a sunnier location or provide supplemental light with grow lights.
* No Sweet Potatoes: This could be due to a number of factors, including insufficient light, poor soil, or lack of fertilization. Make sure your plants are getting enough light, are planted in well-draining soil, and are fertilized regularly. Also, be patient! It takes time for sweet potatoes to develop.
Tips and Tricks for Success
Here are a few extra tips to help you succeed with your indoor sweet potato growing adventure:
* Choose the Right Variety: Some sweet potato varieties are better suited for indoor growing than others. Look for varieties that are compact and early-maturing. ‘Beauregard’ and ‘Jewel’ are popular choices.
* Rotate Your Plants: Rotate your plants regularly to ensure they get even light exposure on all sides.
* Don’t Overwater: Overwatering is a common mistake that can lead to root rot. Let the soil dry out slightly between waterings.
* Be Patient: Growing sweet potatoes takes time and patience. Don’t get discouraged if you don’t see results immediately. Just keep providing your plants with the care they need, and you’ll eventually be rewarded with a bountiful harvest.
* Consider Hydroponics: For a more advanced approach, you can try growing sweet potatoes hydroponically. This involves growing the plants in water with added nutrients, without using soil.

Frequently Asked Questions (FAQ)
What kind of container should I use for growing sweet potatoes?
The ideal container should be large enough to accommodate the growing roots. A minimum of 10 gallons is recommended, but larger is always better. Consider using a plastic tub, a large pot, or even a repurposed container like a laundry basket lined with landscape fabric. Ensure the container has drainage holes to prevent waterlogging, which can lead to root rot. The material of the container isn’t as important as its size and drainage capabilities.
How often should I water my sweet potato plants?
Sweet potatoes prefer consistently moist soil, but not soggy. Water deeply when the top inch of soil feels dry to the touch. During hot, dry weather, you may need to water more frequently. Check the soil moisture regularly, especially if your plants are in a sunny location. Avoid overwatering, as this can lead to root rot. A good rule of thumb is to water thoroughly until water drains from the drainage holes.
What kind of soil is best for growing sweet potatoes?
Sweet potatoes thrive in well-draining, sandy loam soil. This type of soil allows for good aeration and drainage, which is essential for healthy root development. If your soil is heavy clay, amend it with compost, sand, and other organic matter to improve drainage. A slightly acidic to neutral pH (6.0-7.0) is ideal. You can purchase a soil testing kit to determine your soil’s pH and nutrient levels.
How much sunlight do sweet potato plants need?
Sweet potatoes need at least 6-8 hours of direct sunlight per day to thrive. If you’re growing them indoors, place them near a sunny window or supplement with grow lights. Insufficient sunlight can result in leggy growth and reduced tuber production. Rotate your plants regularly to ensure even exposure to sunlight.
How long does it take to grow sweet potatoes using this method?
From slip to harvest, it typically takes 3-4 months to grow sweet potatoes. The exact time will depend on the variety of sweet potato, the growing conditions, and the climate. You’ll know your sweet potatoes are ready to harvest when the vines start to yellow and die back.
Can I grow sweet potatoes from store-bought sweet potatoes?
Yes, you can! Choose organic sweet potatoes to avoid any growth inhibitors that may have been applied. Simply suspend the sweet potato in a jar of water, with the bottom half submerged. Place the jar in a warm, sunny location, and wait for sprouts (slips) to emerge. Once the slips are a few inches long, gently twist them off and root them in water before planting them in your container.
How do I prevent pests and diseases from affecting my sweet potato plants?
Regularly inspect your plants for signs of pests or diseases. Common pests include aphids, spider mites, and sweet potato weevils. You can control these pests with insecticidal soap or neem oil. Diseases such as root rot and fungal infections can be prevented by ensuring good drainage and avoiding overwatering. Crop rotation and using disease-resistant varieties can also help.
Can I grow sweet potatoes indoors year-round, even in cold climates?
Yes, that’s the beauty of this DIY trick! By growing sweet potatoes in containers indoors, you can control the environment and provide the necessary warmth and sunlight, regardless of the outdoor climate. Just ensure you have adequate lighting and maintain a consistent temperature.
What do I do with the sweet potato vines after harvesting the tubers?
The sweet potato vines are edible and can be used in salads, stir-fries, or as a leafy green vegetable. They are a good source of vitamins and minerals. Alternatively, you can compost the vines to enrich your garden soil.
How do I cure sweet potatoes after harvesting them?
Curing sweet potatoes is essential for developing their sweetness and improving their storage life. After harvesting, gently brush off any excess soil and place the sweet potatoes in a warm, humid location (80-85°F and 85-90% humidity) for 7-10 days. This allows the skins to harden and any minor cuts or bruises to heal. After curing, store the sweet potatoes in a cool, dry, and well-ventilated place (55-60°F). Avoid storing them in the refrigerator, as this can cause them to develop a hard core.
What are some common problems when trying to grow sweet potatoes year round?
Some common problems include:
* **Lack of Sunlight:** Insufficient sunlight can lead to weak, leggy growth. Supplement with grow lights if needed.
* **Overwatering:** Overwatering can cause root rot. Ensure good drainage and allow the soil to dry out slightly between waterings.
* **Pests:** Monitor your plants regularly for pests and take action promptly.
