#PlantTheBlock
412 neighborhoods. One climate. Your move.

Seedling's founding volunteer
"I watched my students wilt in classrooms with no air conditioning, while the parking lot outside baked at 108 degrees. One summer I bought a tree. The next summer, I bought ten. By the third summer, the whole block showed up to plant.
"
That was 2021. Today, Seedling channels community dollars into hyperlocal climate projects across 412 neighborhoods — from rooftop rain gardens in East Baltimore to youth-led air-quality monitoring on Chicago's South Side.
We don't believe in abstract climate pledges. We believe in your block, your neighbors, and the single shade tree that changes how a summer feels.

Your block is getting
hotter. Wetter. Harder.
This isn't abstract policy. It's the flooding in your basement, the scorched playground where your kids can't play in July, the tree you watched die three summers ago.

The math is simple.
Green cools. Pavement bakes.
Every square foot of tree canopy reduces surrounding surface temperatures by up to 9°F. Every rain garden absorbs 30% more stormwater than bare soil. Every community composting hub diverts methane from landfills.
The EPA has the data. Your neighbors have the lived experience. Seedling connects the two — and turns your dollars into measurable, mappable change.

"Last summer, my kids could actually play outside past noon for the first time in years. The four trees Seedling planted on our block dropped the sidewalk temp by almost ten degrees."

"I'm a retired science teacher. I watched data for twenty years. What Seedling is doing in East Baltimore is the only intervention I've seen that actually bends the curve."

"My flower shop flooded three times in 2022. We joined Seedling's rain barrel program and haven't flooded since. I didn't need a policy paper — I needed a rain barrel."
