Watermelon seeds should be planted about 1 to 2 inches deep in the soil. This depth provides the right conditions for germination and growth. Typically, seeds are planted in mounds spaced about 4 feet apart, with 4 to 6 seeds per mound, which are later thinned to the strongest plants

. For best results:

• Plant seeds when soil temperatures are at least 65°F to 70°F.
• Use well-drained, fertile soil amended with organic matter.
• Water the seeds after planting to keep the soil moist but not waterlogged

In summary, planting watermelon seeds 1 to 2 inches deep in warm, well- prepared soil is the recommended practice for successful growth.
