Grow Your Own Watermelon from Seed! Instructions: 1. Prepare Soil: Choose well-draining, fertile soil. Loosen the soil to a depth of at least 12 inches and remove any rocks or debris. 2. Plant Seeds: Plant watermelon seeds in hills or rows, spacing them about 6 inches apart. Sow seeds 1 inch deep and cover with soil. 3. Water: Water the soil thoroughly after planting to ensure good seed-to-soil contact. Keep the soil consistently moist throughout the growing season.
