The beautification of the ‘city of culture’ was a huge public realm scheme in the heart of Londonderry. With its origins as a settlement in an Oak Grove it is fitting that upgrades to the centre of Derry (Londonderry) have recognised the importance of long term planning for healthy trees.

The brief included retaining as many of the existing trees as possible and integrating them visually with the new planting. The Landscape Architect – BDP, who specialise in enhancing the natural landscape consulted Greenleaf Ireland for advice on a tree pit design to ensure the establishment and longevity of the trees while working within the budget available.

Planted in the winter of 2009/10 using RootDirectors the new trees roots were diverted downwards into a root friendly zone created by RootCells below the hard surface. Long term aeration and irrigation was provided for by the RootRain Precinct system with bespoke bronze inlets incorporated into the surface.

The existing and new trees were bought together visually using Arboresin support frames, fabricated to bespoke sizes to strengthen the porous resin bound tree pit surfacing. The finished result was such that the same formula was then applied to other existing trees within the city as part of an expanded program of environmental improvements. Arboresin is a well proven hardwearing attractive surface ideal for retrofitting around existing trees to reduce trip hazards.

Greenleaf Ireland, GreenBlue’s long established partner in Ireland, are proud to have played a key part of such an amazing transformation to Derry City Centre – providing green canopy cover and the opportunity for the trees to reach their full potential.
