General Climatic Requirements. Seedless watermelons are a warm-season crop, preferring relatively high temperatures for optimum growth. Daytime temperatures of 80 to 95 degrees F. and night temperatures of 60 to 70 degrees F. are best. When temperatures are lower, plant growth is slowed considerably. With favorable weather, seeded fields can produce ripe fruit in 85 to 100 days.
Planting. Poor seed germination is the main problem with growing seedless watermelons. When direct seeding, the soil temperature should be minimum of 70 degrees [...]
