How To Grow Sweet Potatoes In Containers
Growing sweet potatoes in containers can be a fun and rewarding experience for gardeners of all skill levels. Not only do they produce delicious and nutritious tubers, but they also make attractive ornamental plants. In this article, we'll guide you through the process of growing sweet potatoes in containers.
Choosing the Right Container
The first step in growing sweet potatoes in containers is to choose the right container. Sweet potatoes need a lot of room to grow, so it's important to select a container that is at least 12 inches deep and 18 inches wide. You can use any kind of container, including plastic pots, wooden barrels, or even grow bags. Make sure your container has drainage holes at the bottom to prevent waterlogging.
Selecting The Sweet Potato Slips
Once you have your container, it's time to select your sweet potato slips. Sweet potato slips are young shoots that grow from stored sweet potatoes. You can find sweet potato slips at your local nursery or order them online. Choose slips that are about 6 inches long and have a few leaves.
Before planting your sweet potato slips, you should place them in a warm and humid location with bright, indirect light for a few days. This will encourage the slips to develop strong roots.
Preparing The Soil
Sweet potatoes prefer well-draining soil that is loose and fertile. Fill your container with a mixture of high-quality potting soil, compost, and perlite or vermiculite to improve drainage. You can also add a slow-release fertilizer to provide nutrients throughout the growing season.
Planting The Sweet Potato Slips
When your sweet potato slips are ready, it's time to plant them in the container. Make a hole in the soil that is deep enough to accommodate the roots of the slip. Place the slip in the hole and cover the roots with soil. Water the container thoroughly after planting to settle the soil around the roots.
Caring For Your Sweet Potato Plants
Keep your sweet potato plants well-watered throughout the growing season. They need about an inch of water per week, either from rainfall or irrigation. Monitor the soil moisture and water when the top inch of soil feels dry.
Sweet potatoes are heavy feeders, so fertilize them every two weeks with a balanced fertilizer. Avoid over-fertilizing, which can lead to excessive foliage growth but reduce tuber production.
As your sweet potato plants grow, they may start to produce vines that sprawl out of the container. You can prune these vines to keep the plant compact and promote tuber development.
Harvesting Sweet Potatoes
Sweet potatoes are usually ready to harvest 100-120 days after planting. You can tell that they're ready by checking the size of the leaves and vines. When they start to turn yellow and wither away, it's time to harvest your sweet potatoes.
To harvest your sweet potatoes, gently dig up the soil around the base of the plant with a fork or shovel. Carefully remove the tubers from the soil, being careful not to damage them. Allow the sweet potatoes to dry in a warm, dark location for a few days before storing them.
