Apple Howling takes place on January 5th.
In several counties in Great Britain, including Sussex and Devonshire, men visit apple orchards after sunset. They place bread or cake on the roots of the oldest tree. Then, they pour cider around the tree. Singing and chanting follows to bless the orchard. Finally, they whacked the tree with sticks, and shout, and yell to “wake up” the tree. This is all done in hope of yielding a bountiful crop.
Also know as Apple Wassailing or Wassailing the Apple Tree.
