The grass has discolored under the heat already yellowish. And also on this day in July the sun heats up the ground at 30 degrees Celsius again. Including not only the grasses, but the young trees planted, the city administration a year ago, along the Path of suffering.

50 to 100 liters of drinking water, the staff watering per tree. In the irrigation of the vehicle, which the gardeners refer to lovingly as Wasserkuh, can be transported up to 1,400 litres. "We have adapted our irrigation plans to the past two summers," says Rüdiger Franz. He heads in the city administration, the Department of green-space care and maintenance. 2017 were distributed to approximately 300 cubic metres of water per season, it is now already a 1,200 cubic meters.

as a result, the trees have a higher water. If new trees are planted, such as, for example, at the Jadeweg in Heide-Süd, the administration, therefore, is now more space around the plants.

Because if the temperatures are not lowered even under a starry heaven, would not the trees to rest and are in need of more water.

The criticism of some citizens that the city Council mow too much, the expert says: "There are now many Blühwiesen that we have created ourselves and where we mow just on the edge."
