A major renovation program was undertaken in the 1970's after the garden was hit by a windstorm . Some clearing of a mature and rather overgrown Victorian garden had been done . A storm in January 1972 caused devastation and major replanting took place with the assistance of Sir Harold Hillier , the eminent English plantsman.
What has been created is a very unusual collection of trees and shrubs. Many of which will not be found elsewhere in Ireland. It is open to visitors and has been visited by many worldwide gardening groups and international dendrologists.
Paths meander through the eight acre garden and create surprises and vistas around every corner. The arboretum was extended by an additional seven acres in 2003 with many new rarities, and a special wild flower meadow. It is interesting to watch it develop and become an additional interest to the garden.
