According to an article in The Garden, the 58 acre RHS garden, located on the western edge of Harrogate in North Yorkshire is undergoing a substantial tree planting project. Around 100 trees will be planted around the Harrogate Arms and 200 in the woodland. Curator Paul Cook explained that the trees include a mix of varieties to provide seasonal interest and address environmental concerns (drought and wet weather).

The new Harlow Carr tree mix includes: cultivars of Cornus kousa and Cornus florida; magnolia as they cope well with heavy soil; Nothofagus and Eucryphia to filter pollution, elders and crabapples for culinary use of the berries and fruit in the restaurant; new Quercus cultivars to preserve the oak woodland; and catalpa in containers to provide summer shade in the courtyards.
