Sweet potatoes are a versatile, nutritious, and delicious addition to any homegrown garden. Surprisingly, you don’t need a large plot of land to grow them. With the right approach, you can successfully cultivate sweet potatoes in containers—perfect for those with limited space. This guide provides you with all the details you need, from selecting sweet potatoes to harvesting them.
Materials You’ll Need:
- Organic sweet potato(s)
- A glass or jar for growing slips
- Toothpicks
- A large container (e.g., a planter, grow bag, or bucket)
- High-quality potting mix
- Organic fertilizer
- A sunny location
- Watering can or hose
Step 1: Select the Right Sweet Potatoes
Start with high-quality, organic sweet potatoes. Organic potatoes are less likely to be treated with chemicals that inhibit sprouting, which increases your chances of success.
Step 2: Grow Sweet Potato Slips
Slips are young shoots that grow from the sweet potato. Here are two simple methods to produce slips:
Method A: Whole Potato Approach
- Fill a glass or jar with water.
- Insert toothpicks into the middle of the sweet potato to suspend it above the glass. Submerge the pointed end in water, leaving the top half exposed.
- Place the glass in a sunny spot, like a windowsill.
- Replace the water regularly to keep it fresh.
- In 4-6 weeks, slips will emerge from the top of the potato.
Method B: Sliced Potato Approach
- Cut the sweet potato into 1-inch slices.
- Insert toothpicks into the slices to suspend them halfway in a water-filled container.
- Follow the same care process as the whole potato method.
Once slips grow to 6-8 inches in length, they are ready for transplanting.
Step 3: Transplanting the Slips
- Fill your container with high-quality potting mix, leaving a 3-inch gap at the top.
- Create holes deep enough to bury the roots and 2 inches of the slip’s stem.
- Carefully remove slips from the sweet potato or slice without damaging the roots.
- Place the slips in the soil and cover their roots securely.
- Water thoroughly to settle the soil.
Step 4: Caring for Your Sweet Potatoes
Growing sweet potatoes in containers requires attention to light, water, and nutrients.
- Sunlight: Position the container in a location with at least 6-8 hours of daily sunlight.
- Watering: Keep the soil consistently moist but avoid waterlogging.
- Fertilizing: Feed your plants every 3-4 weeks with organic fertilizer to encourage robust growth.
- Drainage: Ensure the container has drainage holes to prevent soggy soil, which can lead to root rot.
- Pest Control: Check regularly for pests and diseases. Address problems promptly using organic solutions.
Step 5: Harvesting Sweet Potatoes
Sweet potatoes mature in about 3-4 months. Signs of readiness include yellowing leaves and vines dying back. To harvest:
- Gently dig into the soil to uncover the sweet potatoes.
- Be careful not to bruise or damage them during harvest.
- Cure the sweet potatoes in a warm, dry place for 1-2 weeks to enhance their sweetness.
