In recent years, Prague has been gradually transforming its public spaces, and with that, the question of what role urban greenery should play in them has resurfaced. In addition to preliminary work on Charles Square, new trees are also returning to Wenceslas Square, where new rows of trees have already been planted in the lower part, with further modifications planned. According to arborist David Hora, however, simply planting trees isn’t enough. “What’s crucial is what’s underground,” he says.

Charles Square is being revitalized, and Wenceslas Square is also undergoing changes, with new tree-lined avenues returning there. How does Prague generally approach urban greenery today?

The city no longer views greenery merely as an aesthetic accessory, but increasingly as part of the infrastructure that influences the climate, quality of life, and the functioning of public space. It’s good that projects are emerging where trees are returning to places that were previously mainly paved or dominated by traffic. At the same time, however, planting alone is not enough.

In the city, common problems include insufficient root space, poorly designed surfaces, conflicts with utility lines, or inadequate post-planting care. The tree may stand in place, but in the long term, it lacks
