Halle (Saale): New irrigation concept: How often young trees in the hall are cast

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. However, for the chestnut is taken care of: Once per week gardening at the back with a tractor with water tank in the district.

a New irrigation concept: "street trees hits the heat at the toughest"

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.

Eight urban gardeners since April, every day, to trees throughout the urban area, but also shrubs, perennials and green space to irrigate the stone gate and Joliot-Curie-Patz,. Also, the trees are in plant pots on the market, must be maintained. "Street trees shall take the heat on the toughest," explains Franz.

the help of citizens, the consumption on hot days, two to three watering cans of water on the trees pour

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. At the same time, a protective film is anchored in the soil so that the roots extend down into the soil instead of the pavement or the road.

in addition, it is good if local residents have with the trees also in view. "For us, it helps immensely if the citizens of watering on hot days, two to three watering cans of water to the trees," stresses head of Department Franz. Because in spite of the intensive irrigation, it has repeatedly shown that a tree dying because of the drought. In the hall, such cases would occur only occasionally.

criticism of mowing the city rejects expert

To counteract this, plant the city, more recently, other types. Instead of Norway maple is now set to, for example, the city of elms, gum trees and sycamore trees. Rüdiger Franz, however, is not optimistic that this summer will be quite as bad for the trees. "At night, the air cools more than in the past few years," he explains. 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." An example of this can be found along the Hanfwegs on the Dautzsch. It is also important that, even in the front yards higher meadows for insects are to be left.(mz)
