The trees can be real or artificial, no taller than 2m and must have lights.
There will not be an entry fee but entry to view the trees will be by donation and any money raised will be donated to a charity.
The number of entries will be limited to 30. Entries will be set up on December 12 and 13 and the display will open to the public from December 14 to 24 from 10am till 2pm.
Walshe said larger groups will be able to visit outside of those hours by arrangement.
He said For Homes For Farms had indicated they would include a visit to the tree display as part of its bus trip to see the houses entered in the annual Christmas lights competition.
Walshe said now the details had been finalised, all that was needed was volunteers to man the display.
