During periods of intense drought in France, cities have begun using a creative method to protect their urban trees from extreme heat. Instead of relying only on occasional watering trucks, small misting tubes are wrapped gently around the trunks and branches of street trees. These tubes release a fine spray of water at regular intervals, helping the trees stay hydrated during long stretches of hot, dry weather.
The misting system works slowly and efficiently. Rather than flooding the ground with large amounts of water, the tubes release a light mist that cools the bark and surrounding air while allowing moisture to seep gradually into the soil. This approach reduces water waste while ensuring the trees receive steady hydration when rainfall is scarce.
Protecting urban trees is important because they provide shade, improve air quality, and help cool city streets during heatwaves. By installing these misting systems, French cities are giving their street trees extra support to survive harsh climate conditions, ensuring that green canopies continue to shelter urban neighborhoods in the years ahead.
