Stock Photo - 04 November 2023, Brandenburg, Königs Wusterhausen: Holger Zahn (l-r), Managing Director of Späth'sche Baumschulen, Lutz Grille, Vice President of the Berlin-Brandenburg Horticultural Association and Jörg Schneider, Chairman of the Brandenburg-Berlin Association of German Nurseries, stand together at a black pine tree with root ball. The issue of sustainability is becoming increasingly important for Christmas tree sales. Trees produced in the region have a good eco-balance. Smaller Christmas trees are also in vogue. The black pine will be donated to the ""Sonnenhof"" children's hospice. Photo: Joerg Carstensen/dpa. - Königs Wusterhausen/Brandenburg/Germany
