Tree Dressing Day is celebrated annually on the first weekend in December, primarily in the U.K. It was initiated by Common Ground, a charity based in Dorset, to emphasize the importance of trees and promote environmental conservation. The day encourages communities to value and care for trees, reflecting on their significant role in enhancing air quality and overall well-being. Typical customs include dressing trees with ribbons, notes, and lanterns, as well as embracing trees that hold importance within the community. The celebration also invites participants to explore tree dressing traditions from various cultures, fostering a deeper appreciation for trees and their contributions to society.
