Sweet potatoes are one of the easiest and most rewarding crops you can grow at home — even if you don’t have a garden. With the right method, containers can produce an impressive harvest of delicious, nutritious tubers.
Whether you have a balcony, patio, or small yard, this guide will show you the best and most reliable way to grow sweet potatoes in containers from start to harvest.
🌱 Why Grow Sweet Potatoes in Containers?
Growing sweet potatoes in pots offers many advantages:
- Perfect for small spaces
- Better control of soil quality
- Fewer pests and diseases
- Easy harvesting
- Warmer soil = faster growth
Sweet potatoes love warmth, and containers heat up faster than garden soil — a big advantage.
🪴 Best Container for Sweet Potatoes
Sweet potatoes grow underground, so container size matters a lot.
✔ Ideal container:
- At least 12–18 inches (30–45 cm) deep
- Wide rather than tall
- With several drainage holes
✔ Best options:
- Fabric grow bags (excellent choice)
- Large plastic pots
- Wooden boxes with drainage
🚫 Avoid small pots — they will limit tuber size.
🌿 Best Soil Mix
Sweet potatoes need loose, light, well-draining soil.
Recommended mix:
- 40% potting soil
- 30% compost
- 20% coco coir or peat moss
- 10% perlite or sand
The soil should never be compact. Loose soil allows tubers to grow large and smooth.
🍠 Start with Slips (Not Tubers)
Sweet potatoes are grown from slips, not seeds.
What are slips?
Slips are small shoots grown from a mature sweet potato.
