Trees pay for themselves—and then some.

For every dollar invested in urban trees, cities get $2 to $5 back in energy savings, lower healthcare costs, and cleaner air and water. Trees are good for people. And they’re good for our economy. https://t.co/qaBQqVgqt6

Nothing like a day in the park with free trees!

We were thrilled to give away 150 trees at this weekend’s Anacostia River Festival! Vibes were high as neighbors took home native trees to help grow DC’s canopy, showing how trees are not only good for our planet, but fun, too. 🌱

Happy #ArborDay in the City of Trees! 🌳

From Rock Creek to the Anacostia waterfront, trees are woven into the fabric of Washington, DC.

Today we celebrate our city’s homegrown monuments — and the people working to keep it that way. 🌿https://t.co/c5Hm0G9pJv

The Eastern Redbud has entered the chat!🌸

While cherry blossoms claim the spotlight, Eastern Redbuds are native to the region, and right now they’re showing off their showstopping canopies of pink-purple flowers across DC. Keep an eye out for these beautiful blooms this week!

@1a Additionally, we've mapped out "pollinator pathways" in the city, with the goal of planting in these key areas so birds, bees, and other pollinators can navigate our urban environment safely.

[Casey Trees @CaseyTrees]

@1a Trees are the backbone of backyard biodiversity! One well‑placed native tree can cool a yard, soak up stormwater, support pollinators, feed birds, and create habitat in even the smallest spaces.

[Casey Trees @CaseyTrees]

@1a If you want more butterflies, songbirds, and shade on a hotter planet, start by planting a tree—then build the rest of your garden around it. As a nonprofit, Casey Trees plants free trees for DC residents and many cities have similar programs.

Trees are nature's air conditioners and one of the best tools we have to fight climate change.

We’re excited to be featured in this important piece from @ClimateStepsUS about how trees cool and heal our cities. https://t.co/DZJQblORfG

Over 30 protected Heritage Trees at RFK face removal after the DC Council advanced legislation granting developers blanket permission to cut them down.

It's unacceptable.

Sign our petition calling on the Council to preserve as many of them as possible 📣 https://t.co/urPRI2bfqA

NEW: Instead of giving in to development pressure, Rebecca Renard-Wilson decided to protect her family's quarter-acre of woodland in Anacostia—forever.

Read about her decision to place the land under a conservation easement with Casey Trees (from @wcp): https://t.co/OMeRCYGLSs

We have more tips on tree watering here: https://t.co/V1x5w6pnRC

[Casey Trees @CaseyTrees]

It's HOT. And if you're thirsty, young trees are too!

Do a tree on your street or property a favor and give it some water to survive this heat wave 💦🌳
