How to Grow Potatoes in Tennessee?

Different planting methods

When growing potatoes in Tennessee, there are two main methods - hilling and trenching. Hilling is when mounds of soil are formed around single potato plants, resulting in smaller yields but simpler cultivation techniques.


Trenching is when the soil is dug out into a shallow trench and the seed potatoes are laid in the bottom before being covered with soil. This method will give you a larger yield from fewer plants but can be more labour-intensive at planting time.

How to plant potatoes in Tennessee?

Step 1: Begin by selecting your seed potatoes. Avoid purchasing pre-cut pieces as they often contain diseases or pests that can weaken your crop. Instead, choose seed potatoes that are healthy and full of eyes.


Step 2: Cut your seed potatoes into pieces that have two to three eyes each. Make sure you’re wearing gloves during this step as the eye cuts can irritate your skin. Also, keep the cut pieces in a cool, dry place until planting time.


Step 3: You can dig trenches 8-10 inches deep and 12 inches apart when it comes time to plant your potatoes. Or form mounds of soil around individual plants with a 4-6 inch radius. Place your potato pieces in either the trenches or mounds so that they are 6 inches below the surface and cover them with soil. For hilling, continue adding more soil throughout the growing season as the plants grow.


Step 4: Water your potatoes thoroughly at planting time and continue to water every 10-14 days for an optimal yield. Be sure not to overwater, however, as this can lead to poor drainage and cause disease issues in the crop.

Essential Care During Growth

Watering: For potato plants to thrive and produce healthy, high-yielding crops, they need consistent moisture without overwatering. You can determine watering by the soil type and the amount of rainfall.


Potatoes grow best when their roots are kept consistently moist, but not waterlogged or saturated. You can consult with a local horticultural expert if unsure about the right watering schedule. They can provide advice on the specific needs for your geographic area.


Fertilizing: It is also essential for successful planting potatoes in Tennessee. While chemical fertilizers are available, organic fertilizer options may be more suitable given Tennessee’s environmental conditions and climate.


You can use organic fertilizers to provide a slow release of nutrients. For example, compost, manure, or bone meal. It is important to adhere to the recommended application rates, as too much fertilizer can result in an increase in disease and insect issues.


Tips on weed control: Weeds must also be kept under control during potato growth. Hand pulling is an effective way for small-scale gardeners to remove weeds from potato beds. Large growers may need to use herbicides such as Roundup or Finale to prevent weed damage and competition for resources. However, it is important to carefully follow the manufacturer’s instructions when using any type of chemical pest control solution.


Crop rotation: Potatoes should never be planted where they have been grown in the previous two years. Because this could increase the chance of disease and pest issues. Additionally, rotating crops is important to keep soil nutrients healthy and prevent pest and disease build-up in the soil.

Protecting Potatoes from Pests and Diseases

Identify common pests: Potato beetle, wireworm, cutworms, flea beetles, aphids and white grubs are common pests. To identify their presence, look for wilted leaves and spots on the potatoes. Also keep an eye out for unusual activity on the plant, such as clustering around leaves or stems.


Natural and chemical-free methods: Pest control is an essential part of protecting the environment and beneficial insects. Some ways to do this. For example, crop rotation, companion planting with other vegetables that naturally repel pests, creating traps using beer or citrus rinds, hand-picking bugs off of the plant and using beneficial insects like ladybugs to attack pest populations.


How to identify and manage common diseases? Potato diseases are common in Tennessee, including late blight, early blight, black leg, rot nematodes, scab and more. You should be familiar with their symptoms to identify these diseases and manage them effectively.


For example, late blight is a fungal disease that causes spots on the leaves and potatoes. While scab appears as rough, corky lesions. Treatment for these diseases varies depending on severity. For example, crop rotation, use of compost or manure, and application of fungicides.


How to take care of potato plants? To help prevent potato plant pests and diseases, it is important to practice good soil management techniques. For example, keeping the area weed-free and ensuring the soil has proper drainage. Pay attention to signs of disease. This can also help catch a problem before it becomes too severe.


Finally, it is important to select disease-resistant varieties of potatoes. Practice crop rotation with other vegetables that are not susceptible to the same issues when possible. This will reduce the spread of pests and diseases.

Managing Challenges in Tennessee's Climate
