How To Grow Sweet Potatoes In Containers

Sweet potatoes are tropical plants that are often grown in warm and humid climates. However, with the right set up, you can grow them easily in containers even if you live in a cooler climate. Container gardening is an excellent way to grow crops if you lack space or want more control over your soil quality. In this article, we will show you how to grow sweet potatoes in containers.

Choosing Your Container

The container size you choose is essential for growing sweet potatoes. The container should be at least 18 inches deep and 24 inches wide. A larger container will allow your sweet potato vines to spread out and provide more room for your roots to grow. Plastic, clay, or ceramic pots with drainage holes are ideal for sweet potatoes as they retain moisture better. Moreover, plastic containers are less likely to crack or break.

Selecting Quality Soil

Sweet potatoes require well-draining soil with plenty of nutrients. You can make your potting mix by combining equal parts of peat moss, perlite, and vermiculite. Alternatively, you can use a high-quality soil mix made specifically for container gardening. Avoid using garden soil as it may contain weed seeds, pests, or diseases.

Planting Sweet Potatoes

Sweet potato slips are small plants grown from mature sweet potatoes. You can buy sweet potato slips online or at your local nursery. Plant your sweet potato slips about six weeks after the last frost in your region. Before planting, fill the container with the potting mix, leaving about three inches of space at the top. Create a hole in the center of the potting mix, making it deep enough to accommodate the entire slip. Place the sweet potato slip gently into the hole, then cover it with soil. Water the container until the soil is moist but not waterlogged.

Caring For Sweet Potatoes

Sweet potatoes require consistent watering, especially during the hot summer months. Keep the soil moist but do not overwater as it can lead to root rot. Fertilize your sweet potatoes twice a month with a balanced fertilizer or one that is high in potassium. You can also add compost or worm castings to enrich the soil. When the vines begin to grow, train them to grow vertically using stakes or trellises. Prune any dead or yellow leaves to improve air circulation and prevent diseases.

Harvesting Sweet Potatoes

Sweet potatoes are ready for harvest between 90-120 days after planting. When the vines start to turn yellow and wilt, it's time to harvest your sweet potatoes. Gently dig around the plant with a garden fork, being careful not to damage the roots. Lift the entire plant out of the container, then shake off any excess soil. Allow your sweet potatoes to dry in a warm, dark place for two to three weeks. Store your sweet potatoes in a cool, dry place away from sunlight.

Troubleshooting Common Problems

Sweet potatoes are relatively easy to grow, but they can encounter problems like any other crop. Here are some common issues and how to fix them: Pests: Sweet potatoes attract whiteflies, spider mites, and other pests. Treat your plants with insecticidal soap or neem oil to get rid of these pests. Diseases: Sweet potatoes can suffer from root rot, which can be avoided by not overwatering. Remove any diseased plant parts immediately to prevent the spread of disease. Weeds: Regularly remove weeds from your container to prevent competition for resources. Growing sweet potatoes in containers is a fun and rewarding experience. With proper care and attention, you can enjoy a bountiful harvest of delicious and healthy sweet potatoes. Remember to choose a suitable container, quality soil, and follow the proper planting and care instructions. By troubleshooting common problems, you can ensure your sweet potato plants stay healthy and productive.
