Do you want to grow something unique and delicious in your garden? Have you ever considered growing a sweet potato plant? Growing a sweet potato plant isn’t as complicated as you think, and it can be gratifying! This guide will explore a sweet potato plant, how to plant it, choosing the right sweet potato, soil preparation, caring for the plant, and joint problems you might encounter.

What Is a Sweet Potato Plant?

If you’re considering growing a sweet potato plant in your garden, you’ll want to understand what it is and what it can do for you. Sweet potato plants are quickly growing perennial that is native to tropical regions throughout the world. It belongs to the Ipomoea family, a large group of flowering plants related to the morning glory. A well-established sweet potato plant can grow up to 7 feet in length and 2 feet in height. The plant contains large tuberous roots known as “sweet potatoes” with edible leaves and stems.

Sweet potatoes are an excellent choice for home gardens, as they’re easy to grow, disease-resistant, and can be harvested in as little as three months. Not to mention, potatoes are incredibly nutritious and a tasty addition to any meal. Sweet potatoes contain vitamins and minerals, including vitamins A, C, B6, and magnesium. They’re also naturally high in dietary fiber and have a low glycemic index, meaning they’re great for maintaining a healthy blood sugar level.

To successfully grow a sweet potato plant, you’ll need to prepare the soil and provide it with the correct nutrients. The soil should be well-drained, so you may need to add organic matter or sand. You’ll also need to ensure the soil has enough nitrogen to support the growing plant. Once the soil has been prepared, you can plant the sweet potato slips or seed potatoes. Sweet potatoes can be planted directly in the soil or containers as long as the container is large enough to provide enough space for the roots.

Choosing a Sweet Potato

First, you’ll want to pick a sweet potato that is the right size for the space you’re planting in. If you’re planting outdoors, you’ll want to go for a larger sweet potato, as it will need plenty of space to thrive. If you’re growing your sweet potato plant indoors, you can go for a smaller one.

Next, you’ll want to pick out a firm sweet potato with no signs of wetness or mold. You’ll also want to look for a potato that is not sprouting or has any obvious signs of damage.

Finally, look at the sweet potato’s shape and color. Sweet potatoes come in various shapes, from long and thin to short and round. They also come in yellow, white, purple, and orange. Choosing the right shape and color of the sweet potato depends mainly on personal preference and what you plan to do with it.

Soil Preparation

The ideal soil for growing a sweet potato plant is a combination of sand, clay, and organic matter that is slightly acidic with a pH of between 5.5 and 6.5. If your soil is alkaline, add some lime or sulfur to lower the pH. To determine the pH of your soil, you’ll need a soil testing kit.

Add compost to your soil to ensure your sweet potato plant has enough nutrients and organic matter. Compost helps maintain soil fertility, aeration, and water retention and acts as a natural pesticide. Additionally, if planting in containers, use a high-quality potting mix with plenty of organic matter.

Another critical step in soil preparation is getting rid of weeds. Before you plant, turn over the soil and remove any weeds. This will help prevent competition between weeds and your sweet potato plant, ensuring your plant will receive the necessary nutrients.

Planting the Sweet Potato

A sweet potato plant is the perfect place to start if you’re a beginner growing your food. It has an incredibly versatile flavor and is also one of the easiest crops to grow and take care of. With just a bit of knowledge and some TLC, you’ll be able to start and cultivate your sweet potato plant in no time.

The first step to planting a sweet potato plant is to acquire some sweet potato roots. Typically you can find sweet potatoes in any grocery store or farmer’s market. Choose organic, non-GMO sweet potatoes that are large and heavy, with no signs of bruising or sprouting. Once you have your sweet potatoes, you’ll want to create your slips. Slips are the green shoots that grow out of the sweet potatoes. You can buy slips from a greenhouse, or you can create your own by cutting a sweet potato so that each piece has at least one eye. Place the pieces in a jar and fill the jar with water. Put the jar in a warm, sunny spot, and in a week or two, you will have slips that you can plant.

Once you have your slips, it’s time to prepare your soil. Sweet potatoes prefer well-drained, nutrient-rich soil in a raised bed or container. The soil should be loose and sandy, with a pH balance between 5.5 and 6.5. Add a bit of fertilizer to the soil before planting, and give the bed a few inches of water before you start. When you’re ready to plant, place the slips in the soil and cover them with an inch of soil. Remember that sweet potatoes need a lot of space to grow, so make sure to space your slips at least 8 inches apart.

Now that your sweet potatoes are in the ground, the rest is just a matter of maintenance.

Caring for Your Sweet Potato Plant

Caring for your sweet potato plant is an integral part of growing. If you want your plant to thrive and produce a large harvest, you need to give it the attention it needs. Here is a step-by-step guide for how to care for your sweet potato plant:

Watering the Sweet Potato Plant

Developing a consistent watering schedule is the key to success when it comes to watering your sweet potato plant. The best time to water is early morning, before the sun is up, to give the leaves time to dry off before the heat. You should only water the soil, not the plant’s leaves, and use a spray bottle to ensure you don’t miss any spots.

Every plant has different water requirements, so observing the soil before watering your sweet potato plant is essential. If the soil is dry, it’s time to water. Be sure to water deeply, using enough water to reach the roots. Make sure to evenly distribute the water across the entire plant rather than focusing on a single area.

Your sweet potato plant needs about 1-2 inches of water per week. If it’s been hot and dry for several days, you may need to water more frequently to compensate for the lack of rainfall. If it rains, then you should reduce your watering schedule appropriately.

Fertilizing and Mulching the Plant

sweet potato plants need a consistent supply of nutrients to stay healthy and robust, but too much fertilizer can cause stunting and other problems. When fertilizing, use a balanced, slow-release fertilizer, such as 8-8-8, and spread it around the base of the plant. Be sure to water the fertilizer in the well to release the nutrients.

Mulching your sweet potato plant is also essential. Mulching helps to retain soil moisture and keeps the soil temperature more consistent. If you live in a hot climate, it’s essential to mulch your sweet potato plant. You can use organic mulches, like straw, hay, leaves, or grass clippings. If you use an inorganic mulch like black plastic, make sure to leave a two-inch gap between the mulch and the stem of the plant.

For best results, fertilize and mulch your sweet potato plant every few weeks. This will ensure the plant gets all the nutrients and water needed to stay healthy and grow.

Common Problems with Sweet Potatoes

Pests such as caterpillars, cutworms, aphids, and beetles can all be a problem for sweet potato plants. To help prevent these pests, it is essential to use crop rotation and regularly inspect the plants for signs of damage. If pests are found, using an organic insecticide like Neem oil can help eliminate the problem.

Soil-borne diseases, such as fusarium wilt, can also be problematic for sweet potatoes. To avoid these diseases, it is essential to use well-draining soil and rotate crops to avoid introducing the disease to a particular area. Crop rotation is also important to reduce the buildup of pests.

Weeds can also be a problem for sweet potato plants. Keeping the area around the sweet potato plants free of competing weed growth is essential. This can be done by frequently pulling weeds by hand or using a soil blocker. If weed growth persists, spot treatments of an approved herbicide such as glyphosate may be necessary.

Finally, sweet potatoes are susceptible to frost damage. Gardeners should avoid planting them outdoors until all danger of frost has passed. A light blanket can protect the plants if frost is in the forecast.

Harvesting Your Sweet Potatoes

Harvesting sweet potatoes is a great way to enjoy the fruits of your labor after a long process of growing them. You’ll need to wait for the plant’s foliage to die before you can begin harvesting them, which usually takes about three to four months after planting. Once the foliage has died back, it’s time to begin harvesting.

The best time to harvest sweet potatoes is when the temperature is cool, usually in the fall. Start using a garden fork to dig around the sweet potato plants gently. Once you’ve loosened the soil enough, grasp the vine of the sweet potato plant and pull it out. It’s best to scrutinize the potatoes before you store them, as larger sweet potatoes may need to be harvested first to prevent them from rotting if left in the ground.

When you’ve harvested all of your sweet potatoes, place them in a basket or container and take them indoors. Once inside, scrutinize them and remove any potatoes that appear damaged or spoiled. Place the remaining potatoes in an excellent, dry spot with plenty of air circulation and let them cure for about ten days. This allows the sweet potatoes to form a hard protective coating, which helps preserve them for more extended storage.

Once cured, the potatoes are ready for storage. Your best bet is to keep them in an excellent, dry spot with plenty of air circulation. You can also store them in wooden crates or boxes. Be sure to check on your sweet potatoes periodically and remove any that appear to be soft or damaged in any way.


Growing a sweet potato plant is an enjoyable and rewarding experience for both beginner and experienced gardeners. With the proper knowledge, soil preparation, and care, anyone can become a successful sweet potato farmer in no time.

Choosing the right sweet potato type for your particular climate and soil is essential. Be sure to prepare the soil properly and sow the sweet potato in an area with plenty of sun, soil drainage, and water. Watering your sweet potato plant regularly and fertilizing and mulching it during the growing season is essential to producing a good crop. Be mindful of common sweet potato pests and diseases, and ensure you harvest your sweet potatoes at the right time.

You can enjoy a bountiful harvest of delicious sweet potatoes with patience, time, and effort! Whether you’re just a beginner or a seasoned gardener, growing a sweet potato plant is an easy, fun, and rewarding experience that you can enjoy year after year.
