share 40

Sweet potatoes are not only delicious and nutritious, but they can also be grown easily at home, even if you have limited space. Container gardening is an excellent way to cultivate sweet potatoes, allowing you to enjoy the satisfaction of homegrown produce regardless of whether you have a backyard or a small balcony. In this beginner’s guide, we’ll walk you through the steps of successfully growing sweet potatoes in containers.

Selecting the Right Containers

Choosing the right container is crucial for the success of your sweet potato plants. Opt for containers that are at least 12 inches deep and 18 inches in diameter. This size will provide ample space for the sweet potato vines to grow and develop healthy tubers. Make sure the chosen containers have proper drainage holes to prevent waterlogging, which can lead to root rot.

Selecting Sweet Potato Varieties

There are various sweet potato varieties available, each with distinct flavors, colors, and growing requirements. Some popular choices include Beauregard, Covington, and Jewel. Research the specific characteristics of each variety to determine which one suits your taste preferences and growing conditions.

Preparing the Potting Mix

Sweet potatoes thrive in well-draining soil with good fertility. Prepare a potting mix by combining equal parts of compost, potting soil, and perlite or vermiculite to improve drainage. This mix will ensure that your sweet potatoes receive the nutrients they need while avoiding waterlogged roots.

Starting the Slips

Slips are the small sprouts that grow from a mature sweet potato. To start your own slips, place a sweet potato half in a container of water, suspended by toothpicks. The bottom should be submerged, while the top remains above water. Place the container in a warm, sunny spot and change the water every few days. In a few weeks, you’ll notice small sprouts emerging from the top. Once these sprouts are around 6 inches long, carefully remove them from the sweet potato and place them in a separate container of water. They will develop roots, and you can transplant them into your growing containers once the roots are a few inches long.

Planting and Growing

Fill your chosen container with the prepared potting mix and make a hole deep enough to accommodate the slip’s roots. Plant the slip and cover the roots with soil. Water the plant thoroughly. Place the container in a sunny location where the sweet potato will receive at least 6-8 hours of sunlight daily.

As the sweet potato vine grows, it will produce more slips along its length. You can choose to plant these slips in the same container or in separate ones. Regularly water the plants to keep the soil evenly moist but not waterlogged.

Caring for Sweet Potato Plants

Fertilize the sweet potato plants every 4-6 weeks with a balanced, water-soluble fertilizer. Keep an eye out for pests like aphids, spider mites, and whiteflies, and address any infestations promptly. You can also consider using natural pest control methods such as neem oil or insecticidal soap.

Harvesting Sweet Potatoes

Sweet potatoes are ready for harvest when the leaves begin to turn yellow and the vines start to wither. Carefully dig up the tubers using a garden fork or your hands. Allow the harvested sweet potatoes to cure in a warm, dry place for about 2 weeks. This process allows the skin to toughen and the flavors to develop fully.


Growing sweet potatoes in containers is a rewarding experience that brings the joy of homegrown produce to even the smallest of spaces. With the right containers, proper care, and a little patience, you can enjoy a bountiful harvest of sweet and nutritious tubers right from your own home. Start your sweet potato container garden today and relish the satisfaction of watching your plants thrive and your harvest flourish.
