National Tree Day is observed in Luxembourg every second Saturday of November, with the next celebration occurring on November 8. This annual event, established in 1992, encourages people across the country to participate in tree planting activities to enhance the tree population and contribute to biodiversity. The day is marked by various ceremonies and events organized in different locations, primarily within cities, where citizens plant trees and hedges to improve living conditions. This initiative not only addresses environmental issues but also fosters community involvement in ecological efforts. While similar observances exist worldwide, Luxembourg's timing in early November is suitable due to its mild winters, allowing for successful tree planting.
