Join us in celebrating Tree San Diego’s 11th Anniversary through tree-planting, community connection, and climate action!

Join the 2025 PLANT-A-THON with Tree San Diego as we kick off our 11th Anniversary with a powerful planting season full of community action!

​

Over the course of 10 weeks, Tree San Diego will plant and distribute 1,000 climate-resilient trees across communities in need, starting with an epic kickoff in National City where 100 trees will be planted in partnership with the City on October 10. Together with volunteers, local leaders, and environmental champions like you, we will transform streets, schools, and parks—building shade equity and a healthier environment for generations to come.

​​

The PLANT-A-THON is our largest fall planting campaign yet! We are starting in National City, one of our region’s most heat-vulnerable and underserved communities in need of expanded tree canopy and natural solutions that combat rising temperatures. See event details below.
