How To Plant Sweet Potato Slips [ Full Guide ]

Sweet potatoes are not only a delicious and nutritious addition to your diet, but they are also relatively easy to grow. One of the common ways to grow sweet potatoes is by planting sweet potato slips. These slips are essentially small rooted sprouts that develop from mature sweet potatoes. Planting sweet potato slips is a cost-effective and rewarding way to grow sweet potatoes at home. In this comprehensive guide, we will delve into the step-by-step process of planting sweet potato slips, from selecting the right location to harvesting your sweet potatoes.

Quick Answer: How To Plant Sweet Potato Slips

  1. Choosing the Right Location: Select a sunny location with well-drained soil.
  2. Preparing the Soil: Ensure the soil is loose, well-draining, and rich in organic matter.
  3. Selecting Quality Slips: Purchase healthy and disease-free sweet potato slips from a reputable supplier or produce them from a mature sweet potato.
  4. Planting Techniques: Space the slips apart in well-prepared rows and plant them at the right depth.
  5. Care and Maintenance: Water regularly and control weeds to ensure optimal growth.
  6. Harvesting: Harvest sweet potatoes when the leaves start to yellow.

Choosing The Right Location

Sunlight: Sweet potatoes thrive in full sunlight, so choose a location that receives at least 6 to 8 hours of sunlight per day.

Soil Type: The ideal soil for sweet potatoes is well-drained, loose, and rich in organic matter. Sandy loam or loamy soil works well for sweet potatoes. Avoid waterlogged or compacted soil, as it can lead to poor root development and rotting of the tubers.

Temperature: Sweet potatoes require warm soil to thrive. Wait until the soil has warmed to at least 60°F (15°C) before planting the slips. In cooler climates, using black plastic mulch can help warm the soil and promote sweet potato growth.

Preparing The Soil

Soil Testing: Before planting sweet potato slips, it’s beneficial to conduct a soil test to understand the soil’s pH and nutrient levels. Sweet potatoes prefer a slightly acidic soil with a pH between 5.8 and 6.2.

Amending the Soil: If the soil pH is too high, you can lower it by incorporating organic matter such as compost or well-rotted manure. This will also improve the soil structure and provide essential nutrients for the sweet potatoes.

Loosening the Soil: Use a garden fork or tiller to loosen the soil to a depth of at least 12 inches. This will promote good drainage and allow the sweet potato roots to penetrate the soil easily.

Adding Organic Matter: Work in a generous amount of compost or well-rotted manure to improve the soil’s fertility and provide a steady source of nutrients for the sweet potatoes.

Selecting Quality Slips

Propagation from Mature Sweet Potatoes: If you want to produce your own sweet potato slips, select healthy sweet potatoes from the previous harvest. About 12 weeks before your last expected spring frost, place the sweet potatoes in a warm, humid location (around 75-80°F or 24-27°C) to allow the slips to develop. Once the slips are approximately 6-10 inches long, carefully remove them from the sweet potato for planting.

Purchasing Slips: If you prefer to purchase sweet potato slips, ensure you buy them from a reputable supplier. Look for slips that are firm, disease-free, and about 6 to 12 inches in length. This ensures that you are starting with healthy plants that have a higher chance of successful growth.

Planting Techniques

Spacing: Sweet potato plants should be spaced about 12 to 18 inches apart in rows that are 3 to 4 feet apart. This allows the plants to have enough room to spread out and produce tubers.

Planting Depth: When planting the slips, bury them about halfway into the soil, with the leafy portion above the ground. If you are using raised beds, you can form ridges or hills about 6 inches high and 12 inches wide to plant the slips in.

Care and Maintenance: Water the slips immediately after planting to settle the soil and ensure good root-to-soil contact. Water the sweet potatoes regularly, especially during dry periods, but be cautious not to overwater as excessive moisture can lead to rot.

Weed Control: Keep the area around the sweet potato plants free of weeds to prevent competition for water, nutrients, and sunlight. Mulching with straw or organic mulch can be beneficial in controlling weeds and retaining soil moisture.

Fertilization: Sweet potatoes benefit from a balanced fertilizer application at planting and then again about 6 to 8 weeks later. Use a fertilizer with a higher potassium content to promote tuber development.

Watering And Fertilizing Tips

Sweet potatoes (Ipomoea batatas) are versatile, nutritious, and easy to grow in a wide range of climates. Known for their vibrant orange flesh and sweet taste, sweet potatoes are a popular vegetable around the world. One of the most common methods of growing sweet potatoes is by using slips, which are young plants that grow from mature sweet potatoes. Planting sweet potato slips is a straightforward process that can yield a bountiful harvest.

Sweet potatoes thrive in well-drained soil that is rich in organic matter. Before planting your sweet potato slips, prepare the soil by incorporating compost or aged manure to improve its fertility and drainage. It’s important to keep the soil consistently moist, but not overly saturated, throughout the growing season.

To ensure adequate moisture, water your sweet potato plants deeply once or twice a week, especially during hot and dry periods. Avoid watering too frequently, as it can lead to rotting roots or disease. Mulching the soil around the plants with organic matter such as straw or wood chips can help retain moisture and suppress weeds.

Fertilizing sweet potato plants is essential for optimal growth and yield. Before planting, apply a balanced organic fertilizer or compost to the soil according to the recommended dosage on the product label. This will provide the necessary nutrients for the plants to establish strong roots and develop healthy foliage. During the growing season, you can top-dress your sweet potato plants with a nitrogen-rich fertilizer, such as fish emulsion or blood meal, every four to six weeks. This will promote vigorous vine growth and increase the yield of sweet potatoes.

Promoting Growth And Yield

To promote the growth and yield of your sweet potato plants, follow these tips:

  1. Provide Ample Sunlight: Sweet potatoes require full sun to thrive. Choose a planting location that receives at least six to eight hours of direct sunlight daily.

  2. Space Properly: Allow sufficient space between each sweet potato plant to ensure good air circulation and prevent overcrowding. Plant the slips about 12 to 18 inches apart in rows that are spaced three to four feet apart.

  3. Train Vines: Sweet potato vines are vigorous and can cover a large area. Help control their growth by directing the vines to trellises or stakes. This can prevent them from sprawling on the ground and potentially rotting.

  4. Remove Weeds: Weeds compete with sweet potato plants for nutrients and water. Regularly remove weeds from the planting area to reduce their impact on the growth of your sweet potato plants.

  5. Prune Vigorously: Sweet potato plants can benefit from pruning, especially if they become too long or tangled. Trimming back excess foliage can redirect the plant’s energy towards producing more tubers.

  6. Hill the Soil: About four weeks after planting, mound soil around the base of the sweet potato plants. This technique, known as hilling, promotes additional root growth and increases the number of tubers produced. Repeat this process every few weeks as the vines continue to grow.

  7. Promote Pollination: Sweet potato plants produce flowers that require pollination for successful fruit set. Encourage pollinators, such as bees and butterflies, to visit your garden by planting flowers that attract them. Additionally, avoid using pesticides that can harm beneficial insects.
