Let’s Get Connected




“The best time to plant a tree was 20 years ago. The second best time is now.”

Chinese Proverb

By taking action with us, volunteers will learn the fundamentals of planting and caring for trees. It’s also a fun way to meet community leaders and neighbors who align with environmental justice and stewardship. We’re here to guide more healthy trees along your streets, parks, parking lots, schoolyards, backyards, places of worship, and businesses. Among many other co-benefits, together we will implement Climate Action Plans, reduce water and air pollution, provide wildlife habitats, and carry on the legacy of Kate Sessions.
