=== Philippines === Since 1947, Arbor Day in the Philippines has been institutionalized to be observed throughout the nation by planting trees and ornamental plants and other forms of relevant activities. Its practice was instituted through Proclamation No. 30. It was subsequently revised by Proclamation No. 41, issued in the same year. In 1955, the commemoration was extended from a day to a week and moved to the last full week of July. Over two decades later, its commemoration was moved to the second week of June. In 2003, the commemorations were reduced from a week to a day and was moved to June 25 per Proclamation No. 396. The same proclamation directed "the active participation of all government agencies, including government-owned and controlled corporations, private sector, schools, civil society groups and the citizenry in tree planting activity". It was subsequently revised by Proclamation 643 in the succeeding year. In 2012, Republic Act 10176 was passed, which revived tree planting events "as [a] yearly event for local government units" and mandated the planting of at least one tree per year for able-bodied Filipino citizens aged 12 years old and above. Since 2012, many local arbor day celebrations have been commemorated, as in the cases of Natividad and Tayug in Pangasinan and Santa Rita in Pampanga.
=== Poland === In Poland, Arbor Day has been celebrated since 2002. Each October 10, many Polish people plant trees as well as participate in events organized by ecological foundations. Moreover, Polish Forest Inspectorates and schools give special lectures and lead ecological awareness campaigns.
=== Portugal === Arbor Day is celebrated on March 21. It is not a national holiday but instead schools nationwide celebrate this day with environment-related activities, namely tree planting.
=== Russia === All-Russian day of forest plantation was celebrated for the first time on 14 May 2011. Now it is held in April–May (it depends on the weather in different regions).
=== Samoa === Arbor Day in Samoa is celebrated on the first Friday in November.
=== Saudi Arabia === Arbor Day in Saudi Arabia is celebrated on April 29.
=== Singapore === In 1971 a 'Tree Planting Day' was established which in 1990 was replaced by 'Clean and Green Week'.
=== South Africa === Arbor Day was celebrated from 1945 until 2000 in South Africa. After that, the national government extended it to National Arbor Week, which lasts annually from 1–7 September. Two trees, one common and one rare, are highlighted to increase public awareness of indigenous trees, while various "greening" activities are undertaken by schools, businesses and other organizations. For example, the social enterprise Greenpop, which focusses on sustainable urban greening, forest restoration and environmental awareness in Sub-Saharan Africa, leverages Arbor Day each year to call for tree planting action. During Arbor Month 2019, responding to recent studies that underscore the importance of tree restoration, they launched their new goal of planting 500,000 by 2025.
=== Spain ===
In 1896 Mariano Belmás Estrada promoted the first "Festival of Trees" in Madrid. In Spain there was an International Forest Day on 21 March, but a decree in 1915 also brought in an Arbor Day throughout Spain. Each municipality or collective decides the date for its Arbor Day, usually between February and May. In Villanueva de la Sierra (Extremadura), where the first Arbor Day in the world was held in 1805, it is celebrated, as on that occasion, on Tuesday Carnaval. It is a great day in the local festive calendar. As an example of commitment to nature, the small town of Pescueza, with only 180 inhabitants, organizes every spring a large plantation of holm oaks, which is called the "Festivalino", promoted by city council, several foundations, and citizen participation.

=== United States ===
Arbor Day was founded in 1872 by J. Sterling Morton in Nebraska City, Nebraska. By the 1920s, each state in the United States had passed public laws that stipulated a certain day to be Arbor Day or Arbor and Bird Day observance. National Arbor Day is celebrated every year on the last Friday in April; it is a civic holiday in Nebraska. Other states have selected their own dates for Arbor Day. The customary observance is to plant a tree. On the first Arbor Day, April 10, 1872, an estimated one million trees were planted.
