Martin Hüfner and his team love trees – yet they often have to cut them down. The tree care professionals have an exciting spring ahead of them, because Hamburg’s greenery is badly weakened by another dry summer. During storms, this can be dangerous, because the weak trees could fall over or large branches could break off – to prevent this, the arborists are out and about all over Hamburg. We are there when Martin Hüfner works to protect trees on construction sites, gives weak trees back their vitality with the right pruning, but also has to beat hopeless cases.
