Factors that Affect Germination of Watermelon Seeds
Several factors can influence how quickly your watermelon seeds germinate:
Temperature
Watermelon seeds germinate best at soil temperatures between 70°F to 95°F (21°C to 35°C). At these temperatures, the seeds can sprout within 5 to 7 days. Cooler temperatures can significantly slow down the process.
Moisture
Consistent moisture is essential for seed germination. The soil should be kept moist but not waterlogged. Too much water can lead to seed rot, while too little can cause the seeds to remain dormant.
Seed Quality
The quality and freshness of the seeds play a significant role. Fresh, high-quality seeds tend to have higher germination rates and sprout more quickly compared to older seeds.
