Growing sweet potatoes can be a fun and rewarding experience for any gardener. However, not everyone has access to a large garden or plot of land to grow them. Fortunately, growing sweet potatoes in soil bags is a great alternative for those who have limited space or want to avoid digging in the ground. This method allows you to grow sweet potatoes in a small area, such as a balcony, patio, or even indoors.
To start growing sweet potatoes in soil bags, you need a few basic materials such as soil bags, potting soil, and sweet potato slips. Sweet potato slips are small sprouts that grow from the eyes or nodes of a mature sweet potato. You can purchase slips from a local nursery or online, or you can make your own by sprouting a sweet potato in water. Once you have your materials, you can follow a few simple steps to successfully grow sweet potatoes in soil bags.

Preparing for Planting
Before planting sweet potatoes in soil bags, it’s important to prepare the bags and the slips properly. Here are some steps to take:
- Choose a location: Sweet potatoes need a lot of sun and warmth to grow properly, so choose a location that gets full sun for most of the day. The temperature should be consistently above 55°F (13°C), as sweet potatoes do not tolerate frost.
- Purchase or make soil bags: Sweet potatoes can be grown in a variety of containers, including grow bags. These bags should be at least 18 inches deep and 24 inches wide. You can purchase them at garden centers or online, or make your own using burlap or heavy-duty plastic.
- Prepare the soil mix: Sweet potatoes grow best in loose, well-draining soil with plenty of organic matter. Use a soil mix that is specifically formulated for growing vegetables, or make your own by mixing potting soil with compost and other organic matter.
- Sprout the slips: Sweet potatoes are grown from slips, which are small sprouts that grow from the sweet potato itself. You can purchase sweet potato slips online or at garden centers, or you can grow your own by sprouting a sweet potato from the grocery store. To sprout your own, place the sweet potato in a jar of water, with the top third of the potato above the water. Change the water every few days, and within a few weeks, the potato should sprout slips.
- Plant the slips: Once the slips are about 6 inches long, they are ready to be planted. Fill the soil bags with the soil mix, leaving about 2 inches of space at the top. Make a small hole in the soil, and gently place the slip in the hole, burying it up to the leaves. Water the bag thoroughly, and cover the soil with a layer of mulch to retain moisture and suppress weeds.
- Care for the plants: Sweet potatoes need consistent moisture to grow properly, so water the soil bags regularly, keeping the soil moist but not waterlogged. Fertilize the plants with a granular organic fertilizer every few weeks, following the package instructions. Watch for pests and diseases, and treat them promptly if necessary.
Planting and Growing Process
Growing sweet potatoes in soil bags is a great project for gardeners who want to enjoy a delicious and nutritious crop without a lot of space. Here are the steps to follow for planting and growing sweet potatoes in soil bags:
Step 1: Choose the Right Soil Mix
It’s important to choose the right soil mix for your sweet potatoes. A loamy soil mix that is rich in organic matter is ideal. You can use an organic potting mix or make your own by mixing equal parts of sand, soil, and compost.
Step 2: Prepare the Soil Bags
Fill the soil bags with the soil mix, leaving about 2-3 inches of space at the top. Make sure the bags have good drainage holes to prevent water from accumulating at the bottom.
Step 3: Plant the Sweet Potato Slips
Sweet potatoes are usually grown from slips, which are pieces of stem that have been cut from a mature sweet potato. Plant the slips in the soil bags, making sure that the roots are well-covered with soil. Space the slips about 12 inches apart to give them enough room to grow.
Step 4: Water and Fertilize
Sweet potatoes need consistent moisture to grow well. Water the soil bags regularly to keep the soil moist but not waterlogged. Fertilize the sweet potatoes with a balanced fertilizer every 4-6 weeks to encourage healthy growth.
Step 5: Provide Adequate Light and Warmth
Sweet potatoes need full sun to grow well. Place the soil bags in a location that gets at least 6-8 hours of direct sunlight every day. Sweet potatoes also need warmth to grow, so make sure they are in a warm place with temperatures between 75-85°F.
Step 6: Prune the Vines
Sweet potato vines can get quite long, so it’s important to prune them regularly to prevent them from taking over your garden. Cut back the vines to keep them under control and encourage the sweet potatoes to focus their energy on growing larger roots.
Step 7: Harvest the Sweet Potatoes
Sweet potatoes take a long time to mature, usually between 90-120 days. You’ll know they’re ready to harvest when the leaves start to turn yellow and the vines start to wither. Carefully dig up the soil bags and harvest the sweet potatoes. Enjoy your delicious and nutritious crop!
Harvesting and Storing Sweet Potatoes
Once the sweet potatoes have grown to maturity, it is time to harvest them. The best time to harvest sweet potatoes is when the leaves start to yellow and die back, and the vines begin to wither. This usually occurs between 90 and 120 days after planting, depending on the variety and growing conditions.
When harvesting sweet potatoes, it is important to be gentle and careful, as they are sensitive to bruising and damage. Using a garden fork or spade, carefully dig around the base of the plant, loosening the soil. Gently lift the sweet potatoes out of the soil, being careful not to damage them.
After harvesting, it is important to cure the sweet potatoes to ensure that they store well. Curing allows the sweet potatoes to heal any minor cuts or bruises and develop their characteristic sweet flavor. To cure the sweet potatoes, place them in a warm, humid location (80-85°F with 80% humidity) for 10 to 14 days. During this time, the skins will thicken, and the sugars will develop.
Once the sweet potatoes have been cured, they can be stored for several months in a cool, dry location. The ideal storage temperature is around 55-60°F, with a relative humidity of 85-90%. It is important to store sweet potatoes in a well-ventilated area to prevent the development of black rot or other diseases.
When storing sweet potatoes, it is important to keep them separate from regular potatoes, as sweet potatoes are sensitive to cold temperatures and can be damaged by exposure to ethylene gas produced by regular potatoes. To prevent sprouting, store sweet potatoes in a dark location and do not wash them until just before use.
By following these simple steps for harvesting and storing sweet potatoes, you can ensure a healthy crop and enjoy fresh, delicious sweet potatoes for months to come.
Common Problems and Solutions
Growing sweet potatoes in soil bags can be a great way to enjoy a bountiful harvest without the need for a large garden plot. However, like any crop, sweet potatoes can face a range of problems that can impact their growth and yield. Here are some common issues that gardeners may encounter when growing sweet potatoes in soil bags, along with some potential solutions:
Watering Problems
Sweet potatoes need consistent moisture to grow properly, but overwatering can lead to root rot and other issues. Be sure to monitor soil moisture regularly and adjust watering as needed. In addition, make sure that your soil bags have adequate drainage to prevent water from pooling around the roots.
Temperature and Climate Issues
Sweet potatoes are a tropical crop and prefer warm temperatures and plenty of sunlight. If you live in a cooler climate, you may need to take steps to protect your plants from the threat of frost. Consider covering your soil bags with black plastic or other materials to help retain heat and protect your plants.
Soil and Fertilizer Concerns
Sweet potatoes need well-draining soil that is rich in organic matter. Consider using an organic potting mix or adding compost to your soil bags to help improve soil quality. In addition, be sure to fertilize your plants regularly with a balanced fertilizer to help promote healthy growth and development.
Pest and Disease Issues
Sweet potatoes can be vulnerable to a range of pests and diseases, including black rot, vine borers, and sweet potato weevils. Keep an eye out for signs of damage and take action promptly if you notice any issues. Consider using organic pest control methods, such as neem oil or insecticidal soap, to help protect your plants.
By being aware of these common problems and taking steps to address them, you can help ensure a successful harvest of sweet potatoes from your soil bags.
