It is a difficult task to check quality of trees delivered for our projects. We have gained lots of experience over the past years. However we organized a visit to the biggest tree nursery in Czech Republic to get the views on this subject directly from the owner. It was beneficial for both parties to share our experience. The discussion was not only about the quality and defects of the trees, but also about how we should adapt to the climate change. We thank you Arboeko for the time and valued information.
