Trees are particularly important for a healthy urban climate. Summers are getting hotter and hotter, which puts many trees under pressure. Here you can find out why trees always need enough water and how you can best water them.

How to water trees properly

  • First of all, you need a source of water. If there is no rain barrel or public well, you can use tap water. Many houses have a water connection outside for the yard or garden.

  • It is better to water heavily once a week than a little every day. It should be at least 50 liters per tree and watering. Pour the water slowly onto the soil in the root area so that it does not run off again immediately. It helps if you loosen the soil a little before watering.

Why are trees important for the urban climate?

Trees in the city are extremely relevant for the urban climate in many ways.

  1. Trees filter CO2 and other pollutants from the city air. At the same time, they produce oxygen and thus make a significant contribution to air quality in inner-city areas.

  2. Urban trees regulate the temperature. On the one hand, they provide shade and prevent sealed surfaces from heating up. On the other hand, moisture is formed through the vegetation, which has an additional cooling effect.

  3. The general quality of life is enhanced by green spaces and the proximity to parks.
