How to Grow Sweet Potatoes in Containers

Plant – Growing sweet potatoes in containers is a great way to enjoy this delicious and nutritious vegetable, even if you have limited space. Whether you have a small backyard or a sunny balcony, you can successfully cultivate sweet potatoes in pots. In this article, we will guide you through the process of growing sweet potatoes in containers, from selecting the right container to harvesting your bountiful crop.

1. Choosing the Right Container

The first step in growing sweet potatoes in containers is selecting an appropriate container. Opt for a large container with a minimum depth of 12 inches to allow for root development. Make sure the container has drainage holes to prevent waterlogging.

2. Preparing the Potting Mix

Prepare a well-draining potting mix for your sweet potatoes. Combine equal parts of high-quality potting soil, compost, and sand to create a loose and fertile medium. Sweet potatoes thrive in loose soil that provides good aeration.

2.1 Fertilizing the Potting Mix

To enhance the nutrient content of your potting mix, you can add organic fertilizers such as compost or well-rotted manure. Mix the fertilizer into the potting soil before planting your sweet potato slips.

3. Planting Sweet Potato Slips

Purchase sweet potato slips from a reputable nursery or start your own slips by sprouting sweet potatoes. 

Bury the slips in the potting mix, leaving a few leaves above the soil surface. Space the slips around 12 inches apart to allow ample room for growth.

4. Providing Proper Care

Sweet potatoes require specific care to ensure healthy growth and abundant harvest:

4.1 Watering

Keep the potting mix consistently moist but not waterlogged. Water the sweet potato plants whenever the top inch of soil feels dry. Be cautious not to overwater, as this can lead to rotting of the tubers.

4.2 Sunlight

Place your containers in a location that receives full sunlight for at least six to eight hours a day. Sweet potatoes are sun-loving plants and require ample light for optimum growth.

4.3 Temperature and Humidity

Sweet potatoes thrive in warm temperatures between 75°F and 85°F (24°C and 29°C). Maintain a humid environment by misting the foliage regularly, especially in dry climates.

5. Managing Pests and Diseases

Monitor your sweet potato plants for common pests such as aphids, sweet potato weevils, and whiteflies. 

Use organic pest control methods or consult with your local garden center for suitable solutions. Prevent diseases by providing proper airflow and avoiding overcrowding of plants.

6. Harvesting Sweet Potatoes

Your sweet potatoes will be ready for harvest in about three to four months. Look for signs such as yellowing foliage and withered vine growth. 

Carefully dig around the container to avoid damaging the tubers. Gently lift the sweet potatoes out of the soil, brushing off any excess dirt. 

Allow them to cure in a warm and dry location for about a week to enhance their flavor and sweetness.

7. Enjoying Your Homegrown Sweet Potatoes

Now that you have harvested your sweet potatoes, it’s time to savor the fruits of your labor. Sweet potatoes can be used in a variety of delicious dishes, from roasted sweet potato fries to creamy sweet potato soup. 

Get creative in the kitchen and enjoy the natural sweetness and nutritional benefits of your homegrown produce.


Growing sweet potatoes in containers is a rewarding and enjoyable gardening experience. With the right container, well-draining potting mix, and proper care, you can cultivate a thriving sweet potato crop, even in limited space. From selecting the container to harvesting the tubers, each step contributes to the success of your sweet potato venture. 

So roll up your sleeves, grab your gardening tools, and embark on the journey of growing sweet potatoes in containers.
