Let’s get started!

Choosing the Right Variety

When it comes to growing sweet potatoes, choosing the right variety is essential. Different varieties thrive in different climates and soil types, so it’s important to select one that suits your specific conditions and preferences. Here are some factors to consider when deciding on the perfect sweet potato variety for your garden.

How To Grow Sweet Potatoes

Know your climate zone

Sweet potatoes are native to warmer regions and prefer a long growing season with plenty of sunlight. Understanding your climate zone is crucial for successful sweet potato cultivation. In general, sweet potatoes thrive in USDA hardiness zones 9-11, but there are also cold-tolerant varieties available for gardeners in cooler climates. If you live in a colder region, make sure to choose a variety that can withstand lower temperatures and has a shorter growing season.

Consider your soil type

Sweet potatoes are adaptable when it comes to soil types, but they do prefer loose, well-draining soil. Sandy loam or loamy soil with a pH of 5.8 to 6.2 is ideal for sweet potato cultivation. However, if your soil is heavy clay or compacted, you can still grow sweet potatoes by improving the soil’s structure and drainage. Consider adding organic matter, such as compost or aged manure, to improve the soil’s fertility and structure.

Determine your desired flavor and texture

Sweet potatoes come in a variety of flavors and textures, ranging from sweet and creamy to dry and starchy. Some popular sweet potato varieties include Beauregard, Covington, and Jewel, each with its unique characteristics. Do you prefer a sweeter, moister flesh for baking or a drier, starchier texture for frying? Knowing your desired flavor and texture will help you narrow down the sweet potato varieties that will best suit your culinary preferences.

Preparing the Soil

Before planting sweet potatoes, it’s crucial to prepare the soil to create the optimal growing conditions for these root vegetables. Here are some steps to follow when preparing your soil for sweet potato cultivation.

Test the soil pH

Sweet potatoes prefer a slightly acidic soil with a pH ranging from 5.8 to 6.2. To ensure your soil’s pH level is within the ideal range, use a soil testing kit or send a sample to a local agricultural extension office for analysis. If the pH is too high (alkaline), you can lower it by adding organic material like compost or peat moss. Conversely, if the pH is too low (acidic), you can raise it by adding lime or wood ash.

Clear the area

Before planting sweet potatoes, it’s essential to clear the designated area of any weeds, rocks, or debris. Remove any existing vegetation by hand or with the help of a garden tiller. This step will create a clean slate for your sweet potatoes to grow without competition from weeds or obstructions.

Amend the soil with organic matter

Adding organic matter to the soil is crucial for improving its fertility, drainage, and structure. Sweet potatoes thrive in soil enriched with compost, aged manure, or other organic materials. Spread a layer of organic matter, around 2 to 3 inches thick, over the planting area and work it into the soil using a garden fork or tiller. This will provide the necessary nutrients for healthy sweet potato growth and help retain moisture in the soil.

Starting from Slips

Planting sweet potatoes from slips, also known as young sprouts, is a common method of starting your sweet potato garden. Here’s how to get started with slips.

Purchase quality slips

When purchasing slips from a reputable nursery or garden center, select healthy, disease-free slips. Look for slips that have well-developed roots and sturdy stems. Avoid slips with signs of damage or pests. Quality slips will ensure a higher chance of success in growing robust sweet potato plants.

Prepare the slips for planting

Before planting the slips, it’s essential to prepare them properly. Remove any lower leaves or suckers from the slips, leaving only a few leaves near the tip. This will encourage root growth and ensure that energy is directed towards developing a strong root system. Allow the slips to sit in a warm, well-lit area for a day or two to promote callusing, which will protect them from rotting once planted.

Plant the slips in a designated area

Choose a sunny location for planting your sweet potato slips. Dig holes around 4 to 6 inches deep and place each slip in the hole, burying it up to the first set of leaves. Space the slips around 12 to 18 inches apart, giving them enough room to grow and spread. Firmly press the soil around each slip to ensure proper contact with the roots. Water the slips thoroughly after planting to help them establish in their new environment.

Planting from Tubers

Another option for starting your sweet potato garden is planting from tubers. Tubers are mature sweet potatoes that have been sprouted to produce slips. Here’s how to plant sweet potatoes from tubers.

Select healthy sweet potato tubers

When choosing tubers for planting, select healthy specimens that are free from defects, diseases, or signs of decay. Look for firm and well-formed sweet potatoes with no soft spots or blemishes. It’s also essential to choose tubers specifically intended for planting, as some sweet potatoes sold for culinary purposes may be treated with sprout inhibitors.

Cut the tubers into sections

To produce slips from tubers, you’ll need to cut them into sections. Each section should be around 4 to 5 inches long and contain one or two “eyes” – small dimples or sprouts on the surface of the tuber. Make clean, sharp cuts and allow the cut surfaces to dry and callus for a day or two. This will prevent rotting and promote healthy growth.

Cure the cut tubers for a few days

After cutting the tubers into sections, it’s crucial to cure them before planting. Place the cut tubers in a warm, dry area with good air circulation, such as a porch or countertop. Allow them to sit for a few days to allow the cut surfaces to dry fully. Curing the tubers will help prevent rot and ensure the best chances of successful sprouting once planted.

Proper Spacing and Depth

When planting sweet potatoes, proper spacing and planting depth are crucial for optimal growth and yield. Here are some guidelines to follow when it comes to spacing and planting depth.

Give each slip or tuber enough space

Sweet potato plants need room to spread and develop their extensive vine system. Space slips or tubers around 12 to 18 inches apart to allow for ample growth. Leaving sufficient space between plants will help prevent overcrowding, competition for nutrients, and minimize the risk of diseases.

How To Grow Sweet Potatoes

Plant them at the correct depth

When planting slips or tubers, it’s crucial to ensure they are at the correct depth in the soil. If planting slips, bury them up to the first set of leaves, ensuring that the roots are fully covered. For tubers, plant them horizontally in the soil, 3 to 4 inches deep. Placing the slips or tubers at the proper depth encourages healthy root development and reduces the risk of rot or damage.

Consider using ridges or hills

Creating ridges or hills in the planting area is a common practice when growing sweet potatoes. Raising the soil level in rows or mounds helps improve drainage and prevents excess water retention around the plants. Additionally, ridges or hills can create a warmer microclimate, which is beneficial for sweet potato growth. Consider forming ridges or hills at least 8 to 12 inches high and spacing the slips or tubers along the ridges.

Watering and Mulching

Proper watering and mulching are essential for healthy sweet potato growth and development. Follow these tips to ensure your sweet potatoes receive the right amount of moisture and conserve water effectively.

Water consistently but avoid overwatering

Sweet potatoes require consistent moisture throughout the growing season, especially during hot, dry periods. Aim to provide around 1 inch of water per week, either through rainfall or supplemental irrigation. Water deeply, saturating the soil around the roots, but be cautious not to overwater, as excessive moisture can lead to root rot or other fungal diseases. Monitor the soil moisture regularly and adjust the watering frequency accordingly.

Mulch the plants to conserve moisture

Applying mulch around sweet potato plants is an effective way to conserve moisture and suppress weed growth. Spread a layer of organic mulch, such as straw, shredded leaves, or wood chips, around the plants, ensuring it covers the soil surface. The mulch will help retain moisture, regulate soil temperature, and reduce the competition from weeds. Renew the mulch layer periodically throughout the growing season to maintain its effectiveness.

Use organic mulch for added nutrients

Choosing organic mulch can provide additional benefits to your sweet potato plants. As the organic mulch breaks down over time, it releases nutrients into the soil, providing a slow and steady supply of nourishment for the plants. Additionally, organic mulch improves the soil’s structure and fertility, enhancing overall plant health. Consider using compost or well-aged manure as mulch for your sweet potato garden.

Fertilizing Needs

Sweet potatoes are heavy feeders and require adequate nutrition for optimal growth and tuber production. Here’s how to meet the fertilizing needs of your sweet potato plants.

Apply a balanced fertilizer before planting

Before planting sweet potato slips or tubers, it’s beneficial to provide a well-balanced fertilizer to kickstart their growth. Incorporate a slow-release organic fertilizer into the planting area following the manufacturer’s instructions. A balanced fertilizer will provide essential nutrients such as nitrogen, phosphorus, and potassium, promoting healthy root development and overall plant vigor.

Side-dress the plants with nitrogen-rich fertilizer

During the growing season, sweet potatoes benefit from additional nitrogen to support vine growth and leaf development. Side-dressing with a nitrogen-rich fertilizer, such as blood meal or fish emulsion, can provide the necessary boost. Apply the nitrogen fertilizer alongside the plants, keeping it at least a few inches away from the stems. Avoid excessive amounts of nitrogen, as it may lead to lush foliage growth at the expense of tuber production.

Avoid excessive use of nitrogen to prevent vine growth

While sweet potato vines are desirable for their ornamental value and ground cover, excessive vine growth can hinder tuber production. Avoid over-fertilizing with nitrogen, as it may result in vigorous vine growth but smaller tubers. Strike a balance between providing enough nitrogen for healthy plant growth and maintaining a focus on tuber development.

Pruning and Training

Pruning and training your sweet potato plants can help improve airflow, reduce the risk of diseases, and promote even tuber development. Follow these tips for proper pruning and training techniques.

Pinch off suckers and lateral vines

As sweet potato plants grow, they produce suckers and lateral vines, which can compete with the main vine for nutrients and space. Pinching off these side shoots will direct more energy towards tuber production and promote a healthier, more manageable plant. Pinch off suckers and lateral vines when they are around 6 to 8 inches long, using your fingers or sharp pruning shears.

Train the main vine along a trellis or wire

Training the main vine of your sweet potato plant along a trellis or wire can help conserve space and improve air circulation around the plants. As the vine grows, gently guide it onto the trellis or wire, using soft ties or twine to secure it if necessary. This method not only keeps the plant off the ground, reducing the risk of contact with soil-borne diseases, but also makes harvesting easier and more efficient.

Prune damaged or diseased leaves

Regularly inspect your sweet potato plants for damaged or diseased leaves. Diseased leaves can act as sources of infection, potentially spreading diseases to other parts of the plant. Remove any affected leaves promptly to prevent the spread of diseases and maintain plant vigor. Use sterile pruning shears or scissors to make clean cuts, and dispose of the removed foliage away from the garden.

Pest and Disease Control

Monitoring for common sweet potato pests and diseases is essential for maintaining healthy plants and a bountiful harvest. Here’s how to keep pests and diseases under control using organic methods.

Monitor for common sweet potato pests

Sweet potatoes can attract a variety of pests, including sweet potato weevils, aphids, whiteflies, and wireworms. Regularly inspect your plants for signs of pest activity, such as chewed leaves, yellowing foliage, or insect presence. If you notice any pest infestation, consider implementing organic pest control methods, such as handpicking pests, introducing beneficial insects, or using insecticidal soaps or oils.

Use organic pest control methods

When it comes to pest control, organic methods are the best choice for maintaining the health and biodiversity of your garden. Introduce beneficial insects, such as ladybugs or lacewings, that prey on common sweet potato pests. Additionally, you can use insecticidal soaps or oils made from natural ingredients to control pests effectively. Avoid using synthetic pesticides, as they can harm beneficial insects and disrupt the natural balance of your garden ecosystem.

Prevent fungal and bacterial diseases

Sweet potatoes are susceptible to fungal and bacterial diseases such as root rot, stem rot, and leaf spot. To prevent these diseases, practice proper sanitation by removing and disposing of any infected plant material. Providing adequate airflow, moisture control, and avoiding overwatering can also help prevent the onset and spread of diseases. If necessary, apply organic fungicides or bactericides labeled for use on sweet potatoes.

Storage and Culinary Uses

After harvesting your sweet potatoes, proper storage is crucial for preserving their freshness and flavor. Here are some tips on how to store sweet potatoes and make the most of their culinary potential.

Store sweet potatoes in a cool, dry place

Once harvested, sweet potatoes should be cured and stored in a cool, dry location to extend their shelf life.

Clear the area

Before planting sweet potatoes, it’s essential to clear the designated area of any weeds, rocks, or debris. Remove any existing vegetation by hand or with the help of a garden tiller. This step will create a clean slate for your sweet potatoes to grow without competition from weeds or obstructions.

Amend the soil with organic matter

Adding organic matter to the soil is crucial for improving its fertility, drainage, and structure. Sweet potatoes thrive in soil enriched with compost, aged manure, or other organic materials. Spread a layer of organic matter, around 2 to 3 inches thick, over the planting area and work it into the soil using a garden fork or tiller. This will provide the necessary nutrients for healthy sweet potato growth and help retain moisture in the soil.

Starting from Slips

Planting sweet potatoes from slips, also known as young sprouts, is a common method of starting your sweet potato garden. Here’s how to get started with slips.

Purchase quality slips

When purchasing slips from a reputable nursery or garden center, select healthy, disease-free slips. Look for slips that have well-developed roots and sturdy stems. Avoid slips with signs of damage or pests. Quality slips will ensure a higher chance of success in growing robust sweet potato plants.

Prepare the slips for planting

Before planting the slips, it’s essential to prepare them properly. Remove any lower leaves or suckers from the slips, leaving only a few leaves near the tip. This will encourage root growth and ensure that energy is directed towards developing a strong root system. Allow the slips to sit in a warm, well-lit area for a day or two to promote callusing, which will protect them from rotting once planted.

Plant the slips in a designated area

Choose a sunny location for planting your sweet potato slips. Dig holes around 4 to 6 inches deep and place each slip in the hole, burying it up to the first set of leaves. Space the slips around 12 to 18 inches apart, giving them enough room to grow and spread. Firmly press the soil around each slip to ensure proper contact with the roots. Water the slips thoroughly after planting to help them establish in their new environment.

Planting from Tubers

Another option for starting your sweet potato garden is planting from tubers. Tubers are mature sweet potatoes that have been sprouted to produce slips. Here’s how to plant sweet potatoes from tubers.

Select healthy sweet potato tubers

When choosing tubers for planting, select healthy specimens that are free from defects, diseases, or signs of decay. Look for firm and well-formed sweet potatoes with no soft spots or blemishes. It’s also essential to choose tubers specifically intended for planting, as some sweet potatoes sold for culinary purposes may be treated with sprout inhibitors.

Cut the tubers into sections

To produce slips from tubers, you’ll need to cut them into sections. Each section should be around 4 to 5 inches long and contain one or two “eyes” – small dimples or sprouts on the surface of the tuber. Make clean, sharp cuts and allow the cut surfaces to dry and callus for a day or two. This will prevent rotting and promote healthy growth.

Cure the cut tubers for a few days

After cutting the tubers into sections, it’s crucial to cure them before planting. Place the cut tubers in a warm, dry area with good air circulation, such as a porch or countertop. Allow them to sit for a few days to allow the cut surfaces to dry fully. Curing the tubers will help prevent rot and ensure the best chances of successful sprouting once planted.

Proper Spacing and Depth

When planting sweet potatoes, proper spacing and planting depth are crucial for optimal growth and yield. Here are some guidelines to follow when it comes to spacing and planting depth.

Give each slip or tuber enough space

Sweet potato plants need room to spread and develop their extensive vine system. Space slips or tubers around 12 to 18 inches apart to allow for ample growth. Leaving sufficient space between plants will help prevent overcrowding, competition for nutrients, and minimize the risk of diseases.

How To Grow Sweet Potatoes

Plant them at the correct depth

When planting slips or tubers, it’s crucial to ensure they are at the correct depth in the soil. If planting slips, bury them up to the first set of leaves, ensuring that the roots are fully covered. For tubers, plant them horizontally in the soil, 3 to 4 inches deep. Placing the slips or tubers at the proper depth encourages healthy root development and reduces the risk of rot or damage.

Consider using ridges or hills

Creating ridges or hills in the planting area is a common practice when growing sweet potatoes. Raising the soil level in rows or mounds helps improve drainage and prevents excess water retention around the plants. Additionally, ridges or hills can create a warmer microclimate, which is beneficial for sweet potato growth. Consider forming ridges or hills at least 8 to 12 inches high and spacing the slips or tubers along the ridges.

Watering and Mulching

Proper watering and mulching are essential for healthy sweet potato growth and development. Follow these tips to ensure your sweet potatoes receive the right amount of moisture and conserve water effectively.

Water consistently but avoid overwatering

Sweet potatoes require consistent moisture throughout the growing season, especially during hot, dry periods. Aim to provide around 1 inch of water per week, either through rainfall or supplemental irrigation. Water deeply, saturating the soil around the roots, but be cautious not to overwater, as excessive moisture can lead to root rot or other fungal diseases. Monitor the soil moisture regularly and adjust the watering frequency accordingly.

Mulch the plants to conserve moisture

Applying mulch around sweet potato plants is an effective way to conserve moisture and suppress weed growth. Spread a layer of organic mulch, such as straw, shredded leaves, or wood chips, around the plants, ensuring it covers the soil surface. The mulch will help retain moisture, regulate soil temperature, and reduce the competition from weeds. Renew the mulch layer periodically throughout the growing season to maintain its effectiveness.

Use organic mulch for added nutrients

Choosing organic mulch can provide additional benefits to your sweet potato plants. As the organic mulch breaks down over time, it releases nutrients into the soil, providing a slow and steady supply of nourishment for the plants. Additionally, organic mulch improves the soil’s structure and fertility, enhancing overall plant health. Consider using compost or well-aged manure as mulch for your sweet potato garden.

Fertilizing Needs

Sweet potatoes are heavy feeders and require adequate nutrition for optimal growth and tuber production. Here’s how to meet the fertilizing needs of your sweet potato plants.

Apply a balanced fertilizer before planting

Before planting sweet potato slips or tubers, it’s beneficial to provide a well-balanced fertilizer to kickstart their growth. Incorporate a slow-release organic fertilizer into the planting area following the manufacturer’s instructions. A balanced fertilizer will provide essential nutrients such as nitrogen, phosphorus, and potassium, promoting healthy root development and overall plant vigor.

Side-dress the plants with nitrogen-rich fertilizer

During the growing season, sweet potatoes benefit from additional nitrogen to support vine growth and leaf development. Side-dressing with a nitrogen-rich fertilizer, such as blood meal or fish emulsion, can provide the necessary boost. Apply the nitrogen fertilizer alongside the plants, keeping it at least a few inches away from the stems. Avoid excessive amounts of nitrogen, as it may lead to lush foliage growth at the expense of tuber production.

Avoid excessive use of nitrogen to prevent vine growth

While sweet potato vines are desirable for their ornamental value and ground cover, excessive vine growth can hinder tuber production. Avoid over-fertilizing with nitrogen, as it may result in vigorous vine growth but smaller tubers. Strike a balance between providing enough nitrogen for healthy plant growth and maintaining a focus on tuber development.

Pruning and Training

Pruning and training your sweet potato plants can help improve airflow, reduce the risk of diseases, and promote even tuber development. Follow these tips for proper pruning and training techniques.

Pinch off suckers and lateral vines

As sweet potato plants grow, they produce suckers and lateral vines, which can compete with the main vine for nutrients and space. Pinching off these side shoots will direct more energy towards tuber production and promote a healthier, more manageable plant. Pinch off suckers and lateral vines when they are around 6 to 8 inches long, using your fingers or sharp pruning shears.

Train the main vine along a trellis or wire

Training the main vine of your sweet potato plant along a trellis or wire can help conserve space and improve air circulation around the plants. As the vine grows, gently guide it onto the trellis or wire, using soft ties or twine to secure it if necessary. This method not only keeps the plant off the ground, reducing the risk of contact with soil-borne diseases, but also makes harvesting easier and more efficient.

Prune damaged or diseased leaves

Regularly inspect your sweet potato plants for damaged or diseased leaves. Diseased leaves can act as sources of infection, potentially spreading diseases to other parts of the plant. Remove any affected leaves promptly to prevent the spread of diseases and maintain plant vigor. Use sterile pruning shears or scissors to make clean cuts, and dispose of the removed foliage away from the garden.
