What You’ll Need:
– Large container (at least 12 inches deep and 20 inches wide)
– Well-draining potting soil
– Sweet potato slips (young plants or sprouted sweet potatoes)
– Watering can or hose
– Fertilizer (rich in potassium)
Step-by-Step Guide:
1. Choose the Right Container – Select a deep container with drainage holes to prevent waterlogging. Sweet potatoes need room to develop roots, so the bigger, the better.
2. Prepare the Soil – Fill the container with light, well-draining soil. Mix in compost or organic fertilizer to enrich the soil and encourage healthy tuber growth.
3. Plant the Slips – Insert 3-4 sweet potato slips into the soil, ensuring the roots are covered and the leaves are above the soil surface. Space the slips 4-6 inches apart if the container allows.
4. Provide Sun and Water – Place the container in a warm, sunny spot where it gets at least 6-8 hours of sunlight daily. Water consistently to keep the soil moist but not soggy.
5. Fertilize and Care – Feed the plants every 2-3 weeks with a potassium-rich fertilizer to promote tuber development. Avoid over-fertilizing with nitrogen, which encourages leafy growth at the expense of the tubers.
6. Harvesting Sweet Potatoes – Sweet potatoes are ready to harvest 3-4 months after planting, when the leaves start to yellow. Carefully dig around the soil to avoid damaging the tubers.
Tips for Success:
– Mulch the soil surface to retain moisture.
– Rotate the container occasionally to ensure all sides receive sunlight.
– Cure harvested sweet potatoes in a warm, dry place for 1-2 weeks to enhance sweetness.
