What type of temperature does an apple blossom need?

Apple blossoms require a period of chilling temperatures during winter, typically between 32°F to 45°F (0°C to 7°C), to properly develop and bloom in spring. Once the chilling requirement is met, they thrive in warmer temperatures, ideally between 60°F to 75°F (15°C to 24°C) during bloom for optimal pollination and fruit set. Consistent temperatures above freezing are crucial to prevent damage to the blossoms.
