At Casey Trees our mission is simple: To restore, enhance and protect the tree canopy of the nation's capital.

Trees benefit our lives in so many ways. From cleaning the air we breathe and mitigating climate change to creating vibrant public spaces. Since its inception the District has shown a commitment to this vital natural resource, resulting in the ample tree-lined boulevards, parks and green spaces that have earned D.C. the moniker the “City of Trees.” Founded in 2002 to protect this legacy and gain back lost tree cover, Casey Trees connects people to trees through continuing education and community action. Opportunities to get involved are seasonal, so check out our calendar and sign up for the Leaflet newsletter to get updates on all the ways you can help re-tree D.C.

Weekly Watering Alert

Newly planted trees — those that have been in the ground less than three years — require 25 gallons of water, approximately 1.5 inches of rainfall, per week to survive. That’s why every Monday from May 1 through September 30, we post a tree watering alert to let you know whether you should water your trees, hold off, or if it’s up to you. As for this week (May 21-27)? No need to water: The sun has never looked so good! With over 5 inches of rain last week the soil is wet and the trees have had plenty to drink of late. Enjoy the sunshine and another week of no watering duties.
