Trees and Drought
On March 25, 2026, Denver Water declared a Stage 1 drought. While conserving water is important, it’s equally important to continue watering trees to help maintain a healthy urban forest. The Office of the City Forester supports smart water conservation practices and encourages residents to prioritize tree health during dry conditions.
Unlike lawns or annual plants, trees can take years to show signs of stress from reduced watering. By the time damage becomes visible, it may already be too late to reverse. Consistent watering helps trees stay healthy, resilient and better able to provide the shade, cooling and environmental benefits our community relies on.
Tree Watering During Drought
A Stage 1 drought declaration does not mean you should stop watering trees. Trees, especially young or newly planted ones, still need regular watering to survive and thrive.
You do not need to run a full irrigation system to keep trees healthy. Hand watering with a hose on a slow trickle is an effective and water-wise option. Allow water to soak deeply into the soil around the tree’s root zone rather than applying short, shallow watering sessions.
Tree watering needs change throughout the year depending on temperature, rainfall and soil conditions. Even during winter, trees may require supplemental water during long dry periods.
Watering tips include:
- Water slowly and deeply
- Focus near the tree’s dripline (the outer edge of the canopy)
- Water in the early morning or evening to reduce evaporation
- Prioritize newly planted and younger trees, which are most vulnerable during drought
- Check soil moisture before watering to avoid overwatering
