Summer is finally here, but just because our planting efforts are put on hold, this doesn't mean we can forget about our trees. When escaping the blazing sun in the months ahead, we can't neglect the little things when it comes to protecting trees and, just as importantly, keeping in touch with friends in the Casey Trees' community. June's issue of The Leaflet looks back on a great spring planting season, offers reminders on tree care, and asks some tough questions regarding the challenges facing the District.
