City Green appeals for assistance in hydrating the urban trees

In the heart of Germany, the city of Lünen is taking bold steps to combat climate change. The department of urban greenery has been actively planting up to 500 trees each year, including climate-resilient species like threadleaf false indigo, purple ash, European blackthorn, common buckthorn, and native species suitable for the region.

These efforts, initiated several years ago, aim to make Lünen's tree population future-proof. Jürgen Arendes, head of the department of urban greenery, explains this initiative. Trees play a crucial role in urban climates, filtering pollutants, producing oxygen, providing shade, humidifying the air, and contributing to cooling on hot days.

However, the city is currently facing a significant challenge. August 22, 2025, saw numerous street and park trees in Lünen suffer from prolonged drought due to climate change. Many affected trees have already died or had to be felled.

To address this issue, the department of urban greenery is urging the population's support. Planting alone is not enough for the survival of young trees in Lünen. They require regular watering beyond the existing rainfall. The correct method for watering trees in Lünen includes watering in the early morning or late evening, less frequently but thoroughly (one to two times a week), and letting the water seep in at the base of the trunk.

It's essential to avoid watering over the leaves, as it brings little benefit and can be harmful. Older, healthy trees can dry out within a few weeks due to climate change. An additional bucket of water per day can help to keep trees in Lünen healthy.

Unfortunately, many common tree species such as mountain ash, birch, ash, chestnut, and beech are particularly affected in Lünen. The specific tree species selected by the city administration for planting future-proof trees in recent years are not detailed in the available search results.

Despite these challenges, Lünen continues its green initiative, demonstrating a commitment to creating a climate-resilient city for future generations.
