How to Grow Watermelons in Tennessee

Growing watermelons in Tennessee can be a rewarding experience, with the state’s warm summers and fertile soil providing ideal conditions for cultivating these juicy, refreshing fruits. “How to grow watermelons in Tennessee” is a common query among local gardeners and farmers, as it requires specialized knowledge and techniques to ensure a bountiful harvest.

Choosing the Right Variety

Selecting the appropriate watermelon variety is crucial for successful cultivation in Tennessee’s climate. Different varieties thrive under varying conditions, and choosing the right one can make a significant difference in your crop’s yield and quality.

VarietyDescriptionDays to MaturityDisease Resistance

Crimson Sweet	Large, oblong melons with bright red flesh	85-90 days	Anthracnose, Fusarium Wilt
Sugar Baby	Small, round melons with sweet, crisp flesh	75-80 days	Anthracnose, Fusarium Wilt
Charleston Gray	Large, elongated melons with crisp, red flesh	90-100 days	Anthracnose, Fusarium Wilt
All Sweet	Medium-sized, oblong melons with deep red flesh	80-85 days	Anthracnose, Fusarium Wilt

Heat-Tolerant Varieties

Tennessee’s hot and humid summers can be challenging for watermelon cultivation. Heat-tolerant varieties like Crimson Sweet, Charleston Gray, and All Sweet are well-suited for these conditions, as they can withstand high temperatures without compromising fruit quality or yield.

Disease-Resistant Varieties

Disease resistance is another crucial factor to consider when choosing a watermelon variety for Tennessee. Varieties like Crimson Sweet, Sugar Baby, Charleston Gray, and All Sweet offer resistance against common diseases like anthracnose and fusarium wilt, reducing the risk of crop loss and ensuring a healthier harvest.

Site Selection and Soil Preparation

Proper site selection and soil preparation are essential for successful watermelon cultivation in Tennessee. These factors directly impact the plant’s growth, yield, and overall health.

Watermelons thrive in well-drained, fertile soils with a pH range of 6.0 to 6.8. Choose a sunny location with at least 8 hours of direct sunlight per day and ample space for the vines to spread.

Ideal Soil Conditions

Watermelons require nutrient-rich soil with good drainage to prevent root rot and other issues. The ideal soil conditions for watermelon cultivation in Tennessee include:

• pH range: 6.0 to 6.8
• Nutrient levels: High in organic matter, nitrogen, phosphorus, and potassium
• Drainage: Well-draining soil to prevent waterlogging and root rot

Amending the Soil

If your soil lacks the necessary nutrients or has poor drainage, amending it with organic matter like compost, aged manure, or peat moss can greatly improve its quality. Additionally, incorporating fertilizers rich in nitrogen, phosphorus, and potassium can provide the essential nutrients for optimal watermelon growth and fruit development.

Planting and Spacing

Proper planting and spacing techniques are crucial for ensuring adequate air circulation, nutrient uptake, and fruit development in watermelon plants.

Watermelons can be planted either by direct seeding or transplanting seedlings. Direct seeding is preferred in Tennessee’s warm climate, as it minimizes transplant shock and allows the plants to establish a robust root system.

Direct Seeding vs. Transplanting

• Direct Seeding: Plant seeds 1 inch deep and 2-3 feet apart after the last frost date, when soil temperatures reach 70°F or higher.
• Transplanting: Start seeds indoors 3-4 weeks before the last frost date, and transplant seedlings after hardening them off when soil temperatures reach 70°F or higher.

Spacing and Row Arrangement

Adequate spacing is essential for watermelon plants to receive sufficient sunlight, air circulation, and nutrients. Here are the recommended spacing guidelines:

• Plant spacing: 2-3 feet apart in rows
• Row spacing: 6-8 feet apart
• Hill spacing (for traditional hill planting): 6-8 feet apart in all directions

Watering and Fertilizing

Consistent watering and fertilization are crucial for watermelon growth, fruit development, and overall plant health.

Watermelons require approximately 1-2 inches of water per week, depending on soil conditions and weather. Ensure the soil remains consistently moist, but not waterlogged, to prevent root rot and other issues.

Irrigation Methods

Several irrigation methods are suitable for watermelon cultivation in Tennessee, including:

• Drip irrigation: Efficient and targeted water delivery directly to the plant’s root zone.
• Furrow irrigation: Water flows through furrows between raised beds, allowing water to seep into the soil.
• Overhead sprinklers: Provides uniform water coverage but can be less efficient and may promote disease spread.

Fertilizer Requirements

Watermelons are heavy feeders and benefit from regular fertilization. Follow these guidelines for optimal nutrient application:

1. Apply a balanced fertilizer (10-10-10 or similar) at the rate of 1 pound per 100 square feet before planting.
2. Side-dress with ammonium nitrate or calcium nitrate when vines begin to run, providing 1/2 pound of nitrogen per 100 square feet.
3. Repeat side-dressing every 3-4 weeks until fruit starts to develop.
4. Apply a potassium-rich fertilizer (0-0-60 or similar) at the rate of 1 pound per 100 square feet when fruits begin to size up.

Pest and Disease Management

Like any crop, watermelons are susceptible to various pests and diseases, which can significantly impact yield and fruit quality if left unchecked.

It’s essential to monitor your watermelon plants regularly for signs of infestation or disease and take prompt action to prevent further damage.

Common Pests

Some common watermelon pests in Tennessee include:

• Aphids: Small, soft-bodied insects that feed on plant sap, causing wilting and stunted growth.
• Cucumber beetles: Yellow or striped beetles that feed on leaves, stems, and fruits, transmitting bacterial wilt disease.
• Spider mites: Tiny arachnids that create webbing and feed on plant cells, causing leaf discoloration and defoliation.

Disease Prevention and Treatment

Implementing preventive measures and prompt treatment is crucial for managing watermelon diseases in Tennessee, such as:

• Powdery Mildew: A fungal disease causing white, powdery growth on leaves. Treat with fungicides and improve air circulation.
• Fusarium Wilt: A soil-borne fungus that causes wilting and plant death. Rotate crops, use resistant varieties, and follow proper sanitation practices.
• Anthracnose: A fungal disease that causes sunken lesions on fruits and stems. Apply fungicides, remove infected plant material, and rotate crops.

Harvesting and Storage

Proper harvesting and storage techniques are essential to ensure you can enjoy the full flavor and quality of your homegrown watermelons.

Identifying Ripeness

Several indicators can help you determine when watermelons are ripe and ready for harvesting:

• Tendril browning: The tendril closest to the fruit stem turns brown and withers.
• Bottom color: The underside of the watermelon turns creamy or white when ripe.
• Hollow sound: A hollow, dull sound when tapped indicates ripeness.
• Resistance to pressure: The rind should resist pressure when pressed with the thumb.

Handling and Storage

After harvesting, handle watermelons with care to prevent bruising or damage. Store them in a cool, dry place, ideally between 50-60°F, for up to 2-3 weeks. Watermelons can also be refrigerated for longer storage, but their flavor and texture may be affected.

Conclusion

Growing watermelons in Tennessee requires careful attention to variety selection, site preparation, planting techniques, watering, fertilization, pest and disease management, and proper harvesting and storage methods. By following these guidelines and best practices, you can cultivate delicious, juicy watermelons in your home garden or farm, making the most of Tennessee’s favorable growing conditions. Remember, patience, diligence, and a keen eye for detail are key to achieving a bountiful watermelon harvest.
