How to grow sweet potatoes in containers at home

If you’re eager to enjoy the earthy sweetness of homegrown sweet potatoes but limited by space, container gardening is your solution. With the right techniques and a bit of care, you can successfully grow sweet potatoes in containers right at home. In this article, we’ll walk you through the steps to create a thriving container sweet potato garden, bringing the joy of harvesting your own delectable tubers closer than ever.

Advantages of Container Sweet Potato Gardening:

  • Space Efficiency: Containers allow you to grow sweet potatoes even in small spaces like balconies, patios, or windowsills.
  • Soil Control: Using quality potting mix ensures optimal soil conditions for sweet potato growth.
  • Easy Monitoring: Containers make it easier to monitor and control pests and diseases.
  • Portable: You can move containers to maximize sunlight exposure and regulate temperature.

Getting Started:

  1. Selecting Containers: Choose large containers with a minimum depth of 12 inches and sufficient drainage holes. Plastic or fabric containers work well.
  2. Choosing Sweet Potato Varieties: Opt for compact or bush varieties that are well-suited for container gardening. These varieties produce smaller tubers but are perfect for limited space.

Steps to Grow Sweet Potatoes in Containers:

  1. Pre-Sprouting Sweet Potatoes: Begin by sprouting your sweet potatoes. Place them in a warm, humid location with indirect sunlight. Sprouts will emerge from the eyes of the sweet potatoes.
  2. Preparing Containers: Fill the containers with a well-draining potting mix, leaving about 3 inches of space from the top.
  3. Planting Sweet Potato Slips: Prepare sweet potato slips by cutting healthy sprouts with a few inches of the base attached. Plant these slips in the containers, burying them up to the first set of leaves.
  4. Caring for Your Container Sweet Potatoes:
    • Sunlight: Place containers in a sunny location that receives at least 6-8 hours of direct sunlight daily.
    • Watering: Sweet potatoes require consistent moisture. Water the plants when the top inch of soil feels dry, ensuring the soil is evenly moist but not waterlogged.
    • Fertilizing: Apply a balanced liquid fertilizer every 4-6 weeks during the growing season.
    • Vining Growth: Sweet potato vines can be trained to grow vertically by using trellises or stakes.
  5. Harvesting Sweet Potatoes: Sweet potatoes are ready to harvest when the foliage starts turning yellow and dying back. Carefully dig around the base of the plant to avoid damaging the tubers. Allow the harvested sweet potatoes to cure in a warm, dry place for about 10 days.

Tips for Success:

  • Choosing Compact Varieties: Look for compact sweet potato varieties such as ‘Vardaman’ or ‘Beauregard.’
  • Proper Drainage: Ensure containers have proper drainage to prevent waterlogging.
  • Warmth: Sweet potatoes thrive in warm temperatures, so avoid cold drafts or extreme temperature fluctuations.
  • Loose Soil: Loose soil allows sweet potatoes to expand and grow without restriction.

Embrace Homegrown Sweetness:

Growing sweet potatoes in containers empowers you to savor the rich flavors of these delightful tubers even in limited spaces. With the right care and attention, your container sweet potato garden can yield a satisfying harvest that’s not only delicious but also a testament to your gardening skills. By embarking on this rewarding journey, you’ll be adding a touch of nature’s sweetness to your daily life.
