Growing sweet potatoes in containers requires attention to detail, but with the right tips and tricks, you will be able to enjoy an abundant harvest of delicious, homegrown sweet potatoes.
In this article, we will discuss how to grow sweet potatoes in containers easily and how to ensure a successful harvest time and time again. With the right knowledge and materials, you will be well on your way to growing tasty sweet potatoes with minimal effort.
1. Advantages of Growing Sweet Potatoes in Containers
1. Ease of Cultivation
Growing sweet potatoes in containers is relatively easy as compared to traditional in-ground cultivation. Containers provide an easy-to-manage environment, eliminating laborious tasks such as tilling and weeding. Sweet potatoes can even be grown successfully in small containers, making it a viable option for those with limited outdoor space.
Container-grown sweet potatoes offer gardeners flexibility when planning their crops. The plants can easily be moved or rearranged based on light, temperature, and water needs. Sweet potatoes can even be cultivated indoors, in a room with access to natural light and adequate ventilation.
3. Pest Management
Container-grown sweet potatoes are less prone to pest infestations than traditional in-ground crops. Containers can be easily treated with insecticides or pesticides to prevent infestations. Gardeners can also follow cultural practices such as crop rotation to further reduce the chance of pest infestation.
4. Drought Resistance
Due to their shallow root systems, container-grown sweet potatoes are more resistant to drought than in-ground crops. The limited soil space in the container also conserves water, resulting in healthier plants and better yields.
2. Growing Sweet Potatoes: The Basics
Growing sweet potatoes isn’t hard and there are some basic guidelines to make sure you achieve success. Sweet potatoes do best in full sun and need warm temperatures, so they’re great for warmer climates. Here’s a breakdown of what you’ll need to get started:
- Soil: Sweet potatoes grow best in loose, well-drained soil.
- Fertilizer: Add a balanced fertilizer, such as 10-10-10, prior to planting, and then again after the potatoes have sprouted.
- Water: Watering is key, especially when the young tubers are still developing. Keep the soil slightly moist but not soggy.
- Container: Sweet potatoes can be planted in slightly raised beds, or in pots or containers.
Sweet potatoes should germinate within a few weeks if conditions are right. When growing them in containers, you’ll need to provide support for the vines as they grow. Once the tubers start to form, increase the water to encourage better growth.
Harvest your sweet potatoes when the vines turn yellow and begin to die back. These gorgeous vegetables should keep well in a cool dry place for several months.
3. Selecting and Preparing Containers
Once you have determined the plants you would like to grow, the next step is to choose the container. The first step is to always look for a container made of porous material that will allow for proper drainage such as clay. Some items to use that could make great planters are:
- Glazed Ceramic Pots
- Wicker baskets
When selecting a container, consider the size, as different plants need more space than others. If the pot is too small, the plant will suffocate and become root bound. Additionally, when selecting a pot, think about aesthetics, as you want the pot to look nice with your plants in it.
When the container is selected, it is important to properly prepare it for planting. First, you need to clean out an old container and fill it about one-third full of a potting mix. After sprinkling the soil, water the container lightly to help remove any air pockets. After watering, fill it up to ½ inch from the rim with soil and level it off. Now you have a well-prepared container to fill with your chosen plant.
4. The Process of Transplanting Sweet Potatoes
Transplanting sweet potatoes is, at first glance, a daunting task. But before you know it, you’ll be a pro! Follow these steps to ensure a successful transplant.
- Step 1. Start preparing your soil in advance. Add organic material like compost or manure and till your soil 6-8 weeks before you plan to transplant.
- Step 2. When the soil is ready, it’s time to plant your sweet potatoes in starter pots. Leave at least four inches of space between each sweet potato.
- Step 3. After 3-4 weeks of growing in the pots, it’s time to transplant them to the garden.
- Step 4. Dig a hole in the soil that is three times bigger than the size of the sweet potato root. Put a cup of compost or manure into the hole and spread it out.
- Step 5. Place the sweet potato root into the hole with the stem touching the sides of the hole. Fill the hole with soil and then tamp it down.
- Step 6. Water your transplanted sweet potatoes at least twice a week and fertilize them once a month. Monitor the growth of your sweet potatoes and weed around them regularly.
If you follow these simple steps, you’ll be harvesting sweet potatoes in no time! Transplanting sweet potatoes, like all things in life, takes practice. But with patience and care, you can harvest a delicious crop of sweet potatoes.
5. Watering and Fertilizing Sweet Potatoes
is an important part of growing healthy and delicious potatoes. The key is to keep the soil moist but take care not to overwater. Here are some guidelines:
- Ensure the soil remains evenly moist. Sweet potatoes need about 1 inch of water per week, or enough to moisten the top 12 inches of soil.
- Always water in the morning, if possible. This gives the foliage a chance to dry out before nightfall and helps prevent fungal diseases.
- Check the soil daily and water when the soil feels dry. If you dig down a few inches and it feels dry, water your plants until water begins to drain out of the holes at the bottom of the pot.
Fertilization is also essential for a healthy yield. Use a fertilizer that is high in phosphorus but low in nitrogen, such as 5-10-10. When the plants have flowers, apply a side dressing of your fertilizer at a rate of one tablespoon for every foot of the row. Keep an eye on the phosphorus levels in your soil. If it’s low, re-apply your fertilizer every two weeks.
6. Common Problems and Advice on Troubleshooting
1. Rotting Tubers and Poor Growth: One of the primary issues that many growers face is rotting sweet potatoes or poor tuber growth. This problem is often attributed to poorly drained soil. Sweet potatoes require well-draining soil to thrive. If the soil is waterlogged or retains moisture for extended periods, it can lead to rot.
Advice: Ensure that the planting area has good drainage. If you’re using raised beds, ensure they are elevated sufficiently. You can also consider mixing in sand or organic matter like compost to enhance drainage.
2. Yellowing Leaves: If you notice the leaves of your sweet potato plants turning yellow, this could be a sign of various issues such as nitrogen deficiency, over-watering, or pests.
Advice: First, check the moisture level of your soil. If it’s too wet, reduce your watering frequency. If the soil moisture level seems fine, consider a balanced, all-purpose fertilizer to address potential nutrient deficiencies. Lastly, inspect the plant for pests and apply necessary controls.
3. Pests and Diseases: Sweet potatoes are prone to a variety of pests, including sweet potato weevil, wireworms, and flea beetles. Additionally, diseases like Fusarium wilt, sweet potato feathery mottle virus, and root rot can also affect them.
Advice: Regular inspection is key. Check the leaves and stems for signs of damage or pest presence. Use organic or recommended pesticides, and rotate crops to minimize disease buildup. Ensuring good airflow around plants can also reduce fungal issues.
4. Small or Misshapen Tubers: Sometimes, sweet potatoes might grow too small or take on a misshapen form. This can be due to a variety of reasons, including inconsistent watering, overcrowding, or planting in soil with too many rocks or obstructions.
Advice: Ensure consistent watering throughout the growth period. When planting, ensure that plants are spaced adequately to allow tubers to expand. Also, prepare your planting bed by removing large rocks or other obstacles that can hinder growth.
5. Early Sprouting: Storing sweet potatoes in conditions that are too warm can lead to early sprouting.
Advice: Store sweet potatoes in a cool, dark, and well-ventilated area. Avoid storing them near other fruits, as fruits release ethylene gas which can hasten sprouting.
In conclusion, like all plants, sweet potatoes come with their own set of challenges. However, with a bit of attention to detail, understanding of their requirements, and proactive problem-solving, you can enjoy a bountiful harvest of these delicious tubers.
