THE LEAFLET

As we enter September, our Tree Operations team remains dedicated to the vital task of watering and caring for our District’s trees. While temperatures may have started to cool, the thirst of trees persists! Trees can experience dehydration up until they enter dormancy, which occurs after the leaves have fallen and the ground becomes frozen. This makes it crucial to continue watering well into the fall, ensuring the trees are adequately hydrated before the winter months set in.

Throughout the summer, our team has worked tirelessly, braving record-breaking heat to ensure the survival of the most vulnerable trees in the District. But this effort doesn’t just happen in the field—it begins at our headquarters. While homeowners are expected and encouraged to water their newly planted trees, trees planted on public lands by Casey Trees are cared for and watered for up to 4 years by our Tree Operations team. We use GIS analysis to gather data on our past plantings and assess various environmental factors. This analysis allows us to identify which trees are most in need of water and assign priority. Armed with this information, our field crew strategically divides their efforts, covering different parts of the District to maximize the impact of our watering efforts.

Despite our efforts, we can’t reach every tree on our own, and that’s where you come in. We encourage all of you to join us in this essential work. Even though summer is winding down, and winter is still a ways off, our trees need your help now more than ever—especially our street trees, which often go unnoticed. So, as you care for your yard and tend to your thirsty trees, don’t forget to show some love to the leafy friends just beyond your sidewalk. A little extra water goes a long way in keeping our urban forest healthy and resilient!

As we look ahead to the cooler months, it’s also a good time to consider the long-term health of our urban canopy. Trees that are well-watered and cared for now will be better equipped to handle the stresses of winter, including the harsh winds and potential salt exposure from road treatments. By maintaining consistent watering practices through the fall, we’re not only helping trees survive the immediate season but also setting them up for a strong start in the spring. This proactive care is a key part of our commitment to building a greener, healthier District, where trees thrive and continue to provide shade, clean air, and beauty for all to enjoy. Together, we can ensure that the benefits of our urban forest are preserved for future generations.
