Watermelon plants need plenty of space to grow and spread out. Leave about 6 feet of space between each row and 3-4 feet between each plant within the row. This will allow for proper airflow and prevent the plants from competing for nutrients and sunlight.

4. Planting the Seeds

Make small holes in the soil, about 1 inch deep. Place 2-3 watermelon seeds in each hole, and cover them with soil. Water the newly planted seeds gently but thoroughly to ensure good soil contact and promote germination.

It is important to note that watermelons are heavy feeders and require nutrient-rich soil for optimal growth. Applying a balanced fertilizer before planting can help provide the necessary nutrients.

5. Providing Support

While watermelon plants typically sprawl on the ground, you can provide support for the growing fruits to prevent them from touching the soil. This can help reduce the risk of rot and disease. Use trellises, cages, or even old pantyhose to support the developing watermelons. Be sure to secure the fruits gently to avoid damaging them.

6. Watering and Mulching

Watermelon plants need consistent moisture to thrive. Keep the soil evenly moist by providing 1-2 inches of water per week, either through rainfall or irrigation. Mulching around the plants can help retain moisture, suppress weeds, and regulate soil temperature.

7. Thin Out Seedlings

If multiple seeds have germinated in one planting hole, thin out the weaker seedlings to allow the strongest one to grow. This will prevent overcrowding and ensure that the remaining plant receives the necessary nutrients and space to produce high-quality watermelons.

Remember to monitor the weather conditions and react accordingly. If there is a drought, increase watering, and if heavy rains are forecasted, consider covering the plants to protect them from excess moisture.

By following these steps, you will be well on your way to a fruitful watermelon harvest in your Tennessee garden!
