How to Care for Sweet Potato Vine?

How to take care of sweet potato plant? You need to know some things about caring for sweet potato plant. We will provide an overview of irrigation requirements, fertilization techniques, pest and disease control for sweet potatoes.

Irrigation requirements and watering schedules: You should water them 1-2 times per week during the growing season. Or whenever the soil feels dry about an inch below the surface. Make sure not to overwater as this can cause root rot or other diseases.

Fertilization techniques: Sweet potatoes need plenty of nutrients to reach their full potential. Ensure your sweet potato plants get enough nutrients through organic fertilizers. For example, compost or manure. Alternatively, you could use a balanced fertilizer designed specifically for vegetables. Be sure to follow the instructions carefully for both products.

Controlling pests and common diseases: You can start with healthy plants to prevent pests and diseases. Make sure they have good drainage and plenty of air circulation around them. Regularly inspect your plants for signs of damage or disease. Remove any affected plants immediately. You can use organic insecticides or fungicides to control pests and diseases if necessary.

Weed Management

Importance of weed control: It is a critical component of successful sweet potato cultivation. Uncontrolled weeds competing with the sweet potatoes for nutrients, water, and light. This can significantly reduce yields and cause damage to them.

Additionally, some weed species can act as hosts for pests and diseases which may infest the sweet potato crop. You should have a strong weed management program in place for these reasons.

Effective weeding methods: There are various methods of controlling weeds in sweet potato production without harming the plants. For example, hand-weeding, cultivation, mulching and chemical control with herbicides.

Hand weeding is labor intensive but can be effective when done regularly. You can use shallow cultivation with a hoe or other tools to uproot weeds. This helps keep the weed population in check.

Mulching benefits and its role in weed suppression: Mulching is an effective method of controlling weeds. It can suppress weeds and conserve moisture and maintain soil temperature. You can use organic mulches for sweet potato production. For example, straw, hay, leaves, or wood chips. These organic materials break down over time. They also provide additional nutrients to the soil.

You can use plastic weed mat to provide a barrier between the sweet potatoes and weeds. They prevent weed seeds from germinating. It also reduces the need for hand-weeding. You should begin in early spring to get the most benefit from mulching. Before weeds have had a chance to establish themselves. This reduces weed competition and maximizes yields.

When to Harvest Sweet Potatoes in Tennessee?

To make sure they’re at their freshest, it's important to harvest sweet potatoes correctly and store them properly for optimal shelf life.

When to dig sweet potatoes in Tennessee? Sweet potatoes will typically be ready to harvest when the vines on the plants turn yellow and begin to die back. The sweet potatoes should have hard, brown skin that can’t easily be punctured with a fingernail. To make sure they’re completely mature, you can wait until most of the vines have died off before harvesting.

How to harvest sweet potatoes properly? Prepare the soil around the sweet potatoes for easy digging by loosening it with a spade and removing any large stones or debris. Use a garden fork or trowel to start lifting the potatoes from the ground.

Once you’ve dug up most of the potatoes, use your hands to carefully pull any that are left in the ground. After all of the sweet potatoes harvesting, brush off any excess soil. Let them dry in an area with good air circulation before storage.

Post-harvest handling and storage tips: Make sure the potatoes have been completely dried before storage. Keep them away from direct sunlight and extreme temperatures. Because this can cause the potatoes to spoil. For longer storage time, store sweet potatoes in a well-ventilated plastic or paper bag in the refrigerator. But use them within two weeks of harvest for best results.

You can freeze them in airtight containers for one year. You need to follow instructions from the National Center for Home Food Preservation if you plan on canning sweet potatoes. For short-term storage of raw sweet potatoes, leave them in their skins with good air circulation.

Wash them thoroughly and scrub off any dirt before cooking. And lastly, always check for signs of spoilage before using the sweet potatoes. For example, soft spots or mold growth. Discard them immediately if you see any of these signs.

Troubleshooting Common Issues

Yellowing leaves: It is one of the first signs of trouble in any sweet potato crop. This issue can stem from different causes. For example, nutrient deficiencies, over-fertilization, pests, water stress, or disease.

To remedy yellowing leaves, first assess your soil. Determine if it is adequately fertilized and well balanced with nitrogen and phosphorus. If needed, adjust the fertilizer levels accordingly. If fertilization is not the issue, inspect your crop for pest infestations. Treat with an insecticidal spray as needed.

You should water your crops adequately every day, but be careful to avoid over-watering. Finally, watch out for diseases which can cause yellowing leaves. For example, fusarium wilt or verticillium wilt. Treat any diseased plants with a fungicide. Practice crop rotation to avoid further spread of the disease.

Cracked or malformed tubers: Cracking or malformation in sweet potato tubers is generally caused by over-watering, excessive heat, or poor soil conditions. To prevent these issues from occurring, make sure to keep your soil consistently moist by watering regularly but not excessively.

Ensure the area has adequate drainage and avoid planting in overly wet soils. You can also use mulch to retain moisture and regulate soil temperature. If cracking does occur, harvest as soon as possible.

Identifying and managing diseases: Sweet potato crops are susceptible to many different diseases, including alternaria leaf spot, bacterial wilt, and southern blight. Recognize the signs and symptoms of these diseases in order to properly manage them.

Alternaria leaf spot produces dark spots on the leaves that can turn into large patches of necrotic tissue if left untreated. Bacterial wilt is identified by wilting leaves and tubers that are discolored and malformed. Southern blight causes white fungal growth on the stems or tubers, which can cause the plant to be stunted.

To prevent disease spread, avoid working with wet soil when planting sweet potatoes in Tennessee. Practice proper sanitation techniques such as cleaning and disinfecting tools and equipment after use. If disease does occur, remove affected plants immediately and apply fungicides when necessary. Applying organic mulch around the base of the plants to reduce the risk of disease.
