Who We Are

Nangle and Niesen

Betula costata in the Nursery during Autumn

Nangle and Niesen Ltd is a family run tree nursery and for more than 40 years we have grown and supplied field grown trees and hedging plants to the Irish and European markets. Our journey started back in 1973 when the initial 54 acres were purchased in Aherla, Co Cork, just 15 miles west of the City, and work began to prepare the land.

The original founders were Des Nangle and Matthew Niesen Snr and the early days saw a concentration on roses and fruit trees with a small selection of street and amenity trees. Conifers were added shortly afterwards and by the late 70’s the focus had firmly switched to the production of field grown trees.

The mid 90’s brought the first real explosion in the supply of trees with Coolmore Stud in Co Tipperary being an important client at this time. Golf course construction was undergoing a boom in Ireland and we are proud to have supplied trees for Mount Juliet, Fota Island, West Waterford, The K Club and The Heritage to name a few. Some notable private clients at this time included U2 (Bono and The Edge), Chris De Burgh, actors Angela Landsbury and Brian Dennehy, President Mary Robinson and not forgetting Charlie Haughey at Kinseally.

2001 was a year of major expansion with another 50 acres added to the nursery to meet increasing demand. New offices were built with further additions to the loading yards and storage sheds. The next generation had already come on board at this stage with Ronan Nangle joining full time in November 1996 and Matthew Niesen Jnr not long after in 1998. Our staff have also played a very important role in the development of the nursery over the years with Andrew Kelly coming on board in 1994 and Oliver Long since 1996, both are key members of the team to this day.

Ronan and Matthew bought out their fathers, the original founders, in 2008 with RonanĀ  then taking sole control of the nursery in 2017. In addition to his 20 years plus experience in plantsmanship and commercial tree growing, Ronan brings with him a fresh approach and new ideas.
