How To Plant Sprouting Sweet Potato [ Full Guide ]

Sweet potatoes are not only a delicious addition to your diet, but they are also a rewarding crop to grow. One way to start growing sweet potatoes is by using sprouting sweet potatoes. These are sweet potatoes that have been left to sprout, producing "slips" that can be planted to grow new sweet potato plants. In this comprehensive guide, we will walk you through the process of planting sprouting sweet potatoes, from selecting the right variety to planting the slips in containers.

Quick Answer: How To Plant Sprouting Sweet Potato

  1. Select a suitable sweet potato variety for sprouting, such as Beauregard or Georgia Jet.
  2. Choose a healthy, organic sweet potato with visible sprouts.
  3. Cut the sweet potato into sections, each containing a sprout, and allow them to dry for a day.
  4. Prepare a sprouting environment with a mix of water and soil.
  5. Place the sweet potato sections with sprouts into the soil, covering the lower portion of each section.
  6. Keep the soil moist and provide adequate sunlight and warmth for optimal growth.
  7. Transfer the sprouted sweet potato slips into larger containers or a garden bed once they have developed roots and leaves.

Selecting The Right Sweet Potato Variety For Sprouting

Not all sweet potato varieties are ideal for sprouting. Some varieties are more conducive to producing healthy slips which will in turn yield bountiful sweet potatoes. The two widely recommended varieties are Beauregard and Georgia Jet. These varieties are known for their ability to produce vigorous and healthy slips, making them excellent choices for sprouting sweet potatoes and subsequent cultivation.

Preparing The Sweet Potato For Sprouting

Start by selecting a healthy, organic sweet potato with visible sprouts. These sprouts are the precursors to the slips that will be planted to grow new sweet potato plants. Once you have your sweet potato, it’s time to prepare it for sprouting.

Carefully cut the sweet potato into sections, ensuring that each section contains at least one visible sprout. It’s important to handle the sweet potato gently to avoid damaging the sprouts. After cutting the sweet potato, allow the sections to dry for a day. This drying process helps to heal the cuts and decrease the risk of rot when the sweet potato sections are placed in the soil.

Creating A Suitable Sprouting Environment

Next, you’ll need to create a suitable sprouting environment for the sweet potato sections. Prepare a container with a well-draining potting mix. A mixture of equal parts peat moss, perlite, and compost makes for an excellent medium for sprouting sweet potatoes. Fill the container with the potting mix, leaving about an inch of space at the top.

Make small depressions in the potting mix, spaced a few inches apart, to accommodate the sweet potato sections. The depressions should be deep enough to cover the lower portion of each sweet potato section, leaving the sprouts exposed above the soil.

Planting Sweet Potato Slips In Containers

Place each sweet potato section into the prepared depressions in the potting mix. Gently cover the lower portion of each section with soil, ensuring that the sprouts remain above the surface. Water the potting mix thoroughly, ensuring that it is evenly moist but not waterlogged.

It’s essential to provide the sprouting sweet potato with optimal growing conditions to encourage healthy slip production. Place the container in a warm, sunny location, such as a windowsill or a greenhouse. Ideally, the ambient temperature should be between 70°F and 80°F (21°C and 27°C) to promote vigorous and healthy sprout development.

Growing sweet potatoes from sprouting sweet potatoes is a satisfying and straightforward process. By selecting the right sweet potato variety, preparing the sweet potato sections for sprouting, creating a conducive sprouting environment, and planting the sweet potato slips in containers, you can kickstart the growth of new sweet potato plants. After the slips have developed roots and leaves, they can be transferred to larger containers or a garden bed to continue their growth journey. With proper care and attention, you’ll soon be able to harvest your own delicious and nutritious sweet potatoes.

Planting Sweet Potato Slips In Gardens

Sweet potatoes are a versatile and delicious vegetable that can be easily grown in your own garden. While most people start their sweet potato plants from slips, which are young sprouts that grow from the tubers, another method is to plant sprouting sweet potatoes directly in the ground. This alternative approach offers convenience and can be a fun experiment for gardeners of all levels.

Before we delve into the steps of planting sprouting sweet potatoes, it’s worth mentioning the traditional method of using slips. Slips are small sprouts that grow from sweet potato tubers and are typically removed and planted separately. However, if you have sweet potatoes that are already sprouting, you can skip the slip production step and directly plant the sprouting tubers. Here’s how to do it:

  1. Prepare the soil: Sweet potatoes thrive in loose, well-drained soil. Before planting, prepare your garden bed by loosening the soil to a depth of at least 12 inches. Remove any rocks, weeds, or other debris from the area.

  2. Choose the right location: Sweet potatoes require a sunny spot in the garden with at least 6-8 hours of direct sunlight each day. Ensure the area has good air circulation to prevent diseases.

  3. Plant sprouting sweet potatoes: Once you have prepared the soil, dig a hole in the ground that is wide enough to accommodate the sprouting sweet potato tuber. Place the sprouting tuber in the hole with the sprouts pointing upwards and cover it gently with soil, leaving the sprouts exposed.

  4. Spacing considerations: Sweet potatoes require ample space to spread and grow. Space your sprouting sweet potatoes at least 12-18 inches apart to provide them with enough room to develop.

  5. Watering: After planting, water the sweet potatoes thoroughly to settle the soil and provide initial moisture for the sprouting tuber.

  6. Mulching: Cover the soil around the plants with a layer of organic mulch, such as straw or wood chips. Mulching helps retain moisture in the soil, suppresses weeds, and maintains an even temperature.
