Potato Power: A Complete Guide to Planting and Growing in Tennessee

Potatoes, a staple in many cuisines, thrive in Tennessee’s temperate climate. Planting potatoes in this region is a rewarding endeavor that can yield bountiful harvests. This comprehensive guide will provide you with step-by-step instructions on how to plant potatoes in Tennessee, ensuring a successful and fruitful season.

Choosing the Right Potatoes

The first step is selecting the right potato variety for your Tennessee garden. Choose varieties that are disease-resistant and well-suited to the state’s climate. Some popular options include:

• Yukon Gold
• Red Pontiac
• Russet Burbank

Preparing the Soil

Potatoes prefer well-drained, loose soil with a pH between 5.5 and 6.5. Before planting, amend the soil with organic matter such as compost or manure to improve its structure and fertility. Remove any large rocks or debris that may hinder root growth.

Planting Time

In Tennessee, the ideal time to plant potatoes is in early spring, between March and April. The soil temperature should be at least 45°F (7°C). Avoid planting in cold or wet conditions.

Seed Preparation

Before planting, cut potatoes into seed pieces that are about 2 inches in diameter and have at least one “eye” (small bump where sprouts emerge). Allow the seed pieces to dry for a few days before planting to reduce the risk of rotting.

Planting Process

1. Dig Trenches: Dig trenches in the prepared soil about 4-6 inches deep and 12-18 inches apart.
2. Place Seed Pieces: Place the seed pieces in the trenches, with the eyes facing up. Space the pieces 12-15 inches apart.
3. Cover Trenches: Fill the trenches with soil and gently pat down to firm.

Watering and Fertilizing

Water the potatoes regularly, especially during dry spells. Avoid overwatering, as this can lead to root rot. Fertilize the potatoes once a month with a balanced fertilizer according to the manufacturer’s instructions.

Hilling

As the potato plants grow, hill up the soil around the base of the stems. This process encourages root growth and prevents greening of the tubers.

Pest and Disease Control

Potatoes are susceptible to various pests and diseases. Common issues include:

• Colorado Potato Beetles: Handpick beetles or use an insecticidal soap.
• Aphids: Use insecticidal soap or neem oil.
• Early Blight: Use copper-based fungicides.
• Late Blight: Remove and destroy infected plants and use fungicides.

Harvesting

Potatoes are ready to harvest when the foliage turns yellow and dies back. Dig up the tubers carefully using a spade or fork. Allow the potatoes to dry in a cool, dark place for a few days before storing.

Storing Potatoes

Store potatoes in a cool, dark, and dry place with good ventilation. Ideal storage conditions are between 40-45°F (4-7°C) and 85-90% humidity.
