California Arbor Week
March 7, 2029 - March 14, 2029
California Arbor Week is celebrated March 7–14 each year.
🌳 It’s California Arbor Week (March 7–14) — a time to celebrate the trees that help sustain our communities and our planet. From cleaner air to cooler neighborhoods, trees play a vital role in climate resilience and environmental health. Let’s continue planting, protecting, and caring for the green spaces that support a thriving future.
It begins on March 7, the birthday of famed horticulturist Luther Burbank, whose work with plants and trees inspired California’s tree-planting tradition.
