Step-by-step guide to planting sweet potatoes

Before planting sweet potatoes, it’s essential to prepare the soil adequately. You’ll need to loosen the soil and add compost or organic matter to improve its fertility.

Then, choose the right variety of sweet potatoes, which comes in different sizes and colors. You can purchase slips or propagate them from vine cuttings. Cut the sweet potato slips to a length of about 6 inches and allow them to cure for a week or two to prevent rotting.

Plant sweet potato slips in a well-draining soil, ensuring they are six to eight inches apart with a depth of four to six inches. As the sweet potato grows, make sure to weed it regularly, add organic matter, and water it regularly.

As the summer ends, watch out for the yellowing of the leaves, which signals harvesting time.

Container planting

If you have limited outdoor space or want to make planting sweet potatoes more accessible, container planting is a viable option. Choose a pot that can accommodate at least five gallons of soil and ensure that the climate is suitable for growing sweet potatoes.

You can transplant sweet potatoes into the soil when you notice growth after several weeks, ensuring the vines are not covered entirely by soil. Regularly water and fertilize the sweet potato, and use mulch to retain moisture. The best way to harvest sweet potatoes from pots is by tipping them over onto a tarp or your garden bed.

Companion planting

Companion planting is planting different crops next to each other to enhance their growth and prevent pests and diseases. Sweet potatoes have few companion plants, so growing them beside other root vegetables such as carrots, radishes, or garlic would be best.

Plant the companion plants during a different planting season to ensure they do not compete for nutrients when growing with the sweet potatoes. This method provides a natural and pest-free way to boost growth and maximize space utilization.

Soil preparation

Before planting sweet potatoes, it’s essential to know the type of soil and pH to ensure its optimal growth. You can purchase soil testing kits from local garden stores to check the soil’s pH; the preferred reading is between 5.5-6.5.

Organic matter such as compost or manure is beneficial to your sweet potato plant. Ideal times to amend soil are after the summer crop or in the early spring if you are planting during the fall season.

Pest and disease prevention

Sweet potato plants are prone to root-knot nematodes and pests such as sweet potato weevils and spider mites. A natural solution is to spray the plants with neem oil or insecticidal soap. To prevent nematodes, crop rotation is the best solution.

Choose disease-resistant and pest-resistant varieties to make pest prevention easier.

Harvesting and storage

When leaves begin to yellow, it’s harvest time. Sweet potatoes do not store well in cold temperatures. Store them in a dry and cool place around 60-75 degrees Fahrenheit.`

Innovative or alternative methods

Unconventional methods of planting sweet potatoes like hydroponics and potato boxes involve using alternative mediums such as sand and peat moss, water and soil to plant sweet potatoes.

Hydroponic systems maintain consistent access to water and nutrients, while potato boxes offer a suitable environment with adequate airflow. However, these methods require more maintenance and often produce fewer yields than traditional planting methods.

Conclusion

Planting and harvesting sweet potatoes at home can be an exciting and rewarding venture if you follow the right procedures. Experiment with different methods to find what works best for you and your plants.
