What To Know
- The ideal time to transplant sweet potatoes is when the soil temperature has reached at least 65°F (18°C) and the risk of frost has passed.
- Store sweet potatoes in a cool, dark, and well-ventilated place with a temperature between 50-60°F (10-15°C) and a relative humidity of around 80%.
- Plant the slips with the roots spread out and the top of the root ball level with the soil surface.
Sweet potatoes, known for their vibrant orange flesh and nutritional value, are a delicious and versatile vegetable that can thrive in home gardens. Transplanting is a crucial step in the sweet potato growing process, and understanding the proper techniques can significantly impact your harvest. This comprehensive guide will provide you with all the information you need to successfully transplant sweet potatoes for optimal growth and yield.
Selecting the Right Time
The ideal time to transplant sweet potatoes is when the soil temperature has reached at least 65°F (18°C) and the risk of frost has passed. Warm soil promotes root development and encourages healthy growth. In most regions, this typically occurs in late spring or early summer.
Preparing the Soil
Soil preparation is essential for successful sweet potato transplantation. Choose a well-drained site with loose, sandy soil that is rich in organic matter. If your soil is heavy or compacted, amend it with compost or aged manure to improve drainage and fertility. The pH level should be between 6.0 and 6.5.
Choosing Healthy Slips
Slips are young shoots that grow from the roots of mature sweet potatoes. They are the preferred method of propagation for transplanting. Select healthy, vigorous slips that are free of pests and diseases. Avoid slips that are leggy or have yellowing leaves.
Hardening Off Slips
Before transplanting, it is important to harden off the slips to help them adjust to outdoor conditions. Gradually expose the slips to direct sunlight and outdoor temperatures over a period of several days. This process will strengthen the slips and make them more resistant to stress.
Digging and Planting
Dig holes that are deep enough to accommodate the entire root system of the slip. Space the holes 12-18 inches apart in rows that are 3-4 feet apart. Gently remove the slip from the container and place it in the hole with the roots spread out. Fill the hole with soil and gently firm it around the base of the plant.
Watering and Mulching
Water the newly transplanted sweet potatoes deeply and regularly, especially during hot, dry weather. Mulching around the plants with straw, hay, or compost helps retain moisture, suppress weeds, and regulate soil temperature.
Fertilizing
Sweet potatoes are heavy feeders and require regular fertilization. Apply a balanced fertilizer, such as a 10-10-10 formula, every 4-6 weeks throughout the growing season. Follow the application instructions carefully.
Pest and Disease Control
Sweet potatoes are susceptible to a few pests and diseases, including sweet potato weevils, aphids, and soil-borne diseases. Monitor your plants regularly and take appropriate control measures as needed. Organic pest control methods, such as companion planting and neem oil, can be effective in managing these issues.
Harvesting
Sweet potatoes are ready to harvest when the leaves turn yellow and the vines start to die back, typically 100-120 days after transplanting. Carefully dig up the roots with a spade or garden fork. Handle the sweet potatoes gently to avoid bruising.
Storing
Store sweet potatoes in a cool, dark, and well-ventilated place with a temperature between 50-60°F (10-15°C) and a relative humidity of around 80%. Proper storage conditions can extend the shelf life of sweet potatoes for several months.
