Because sunflowers are tropical plants, they are very adaptable to temperature. When the temperature is stable above 2 degrees Celsius, seeds can slowly begin to germinate. When the ground temperature exceeds 8 degrees Celsius, it is the basic need for seedlings to emerge. The best temperature for real germination is above 30 degrees, but not more than 40 degrees.
