General Fruit Tree Information:

  • Fruit Tree Chilling Requirements:
    • Dormancy is broken when sufficient cold temperature breaks down the growth inhibitors within the tree. This is called vernalization, “chilling,” or “winter chill.” A specific number of cumulative hours of chilling (temperatures between 32°F – 45°F), are required to break dormancy, which varies from variety to variety.
