California Arbor Week
Celebrated Annually March 7 – 14
What is California Arbor Week?
Unlike most Americans who celebrate Arbor Day at the end of April, California celebrates Arbor Day early on March 7th in honor of famed California Horticulturalist Luther Burbank’s birthday. In 2011, the California State Assembly and Senate approved Resolution ACR 10 (Dickinson), making California Arbor Day a week-long celebration during March 7 – 14 every year.
Celebrating California Arbor Week
Trees bring life to California – and that is worth celebrating! During Arbor Week, commemorative events are held throughout the state. Cities, community groups, and individuals plant trees, host tree planting ceremonies, and educate California’s youth about the remarkable work trees do for our communities every day- from cleaning the air and water to improving the overall health of our neighborhoods.
