Summer Tree Care

Help us care for trees this summer! Your help with weeding, mulching and watering these vulnerable young trees will help them survive the heat and help us reach our 40 percent canopy cover goal.


Our Mission: 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 (Jul 16 – Jul 22)? Water those trees! We are mid-way through July; the soil is dry and the temperatures are high. Our crews are out watering every day — supplement our efforts by watering newly planted trees on your property or in your neighborhood. #25toStayAlive
