Trees for the Future Without any doubt trees are important to ensure the quality of life in urban areas. Research has proven that in many ways, but how can we plant trees in such a way that they contribute to a green city? What kind of tree have the most effect? And which trees can withstand the urban climate and grow under difficult circumstances? What kind of trees are the most effective in reducing temperature or improving air quality? Important question for landscape designers and architects. At Van den Berk Nurseries they have amassed a lot of knowledge on this subject and they know how trees grow, even after 25 or more years. This knowledge makes it possible to give landscapers good advice on planting trees in urban environment. They can advise on species, including less commonly used ones, that can resist the urban heating or are effective in capturing CO2. Depending on the main goals of the architect and the desired sphere, they can make a tailored proposal. On request they also give lunch time presentations on this topical issue. Another challenge in urban areas is the planting site itself. Trees are surrounded by buildings, roads, pavement and other development. It’s a tough combination because civil engineers and trees almost always have a conflicting interest. Underground space, or the lack of it, is a very common problem. Roots have to compete with an ever growing web of pipes, sewers and cables and there is often too little room for them to be able to develop in the long term. The tree technician of Van den Berk Nurseries can also advise on the improvement of planting sites and what can be done to give trees a better chance to grow old. For more information go ΂
