Tree Dressing Day is an annual celebration in the UK held on the first weekend of December. Established in 1990 by Common Ground, a UK-based charity dedicated to environmental education and community conservation, this day serves as a tribute to the significance of trees and a reminder to care for them.

Beyond appreciating the intrinsic value of trees, Tree Dressing Day provides communities with an opportunity for reflection on the historical and cultural impact of trees in shaping the local social fabric.
