In principle, the street and green space authorities of the districts are responsible for watering urban trees. However, some districts also repeatedly ask Å·ÃÀÇéÉ«ers for help. The districts of Mitte, Friedrichshain-Kreuzberg, Reinickendorf, Lichtenberg and Neukölln are currently calling for young trees to be watered. The trees should be watered thoroughly once or twice a week, "preferably less often, but with larger amounts of water (at least 75-100 liters per watering), instead of only small amounts every day," a spokesperson for the Mitte district office said in response to a request. It makes sense to water in the evening or in the morning.
