Up to 10,000 plants and flowers will be arranged in front of the Pikeman Memorial, in Denny Street, creating a spectacular display that will last until October.
Thirty volunteers, assisted by staff from Tralee Town Council, FÁS and Breannan Services, will start work under the landmark Pikeman, at 6.30pm, on Monday, and the task should be completed well before Tralee wakes up on Tuesday morning.
Known as a Guerilla Garden, the concept started in America and has been brought to the Kerry capital by the Towards A Better Tralee group, under the chairmanship of Cllr Johnny Wall.
Tralee woman Annette Dalton, who is curator at the famous Kew Gardens, in London, has designed the display and will supervise the operation on Monday.
“This is part of a massive Tidy Towns initiative in Tralee this year.
“It is also to celebrate the centenary of the Pikeman Memorial,” John Griffin, secretary, Towards A Better Tralee said.
The plants and flowers will come from the St John of God Nursery, Monavalley, Tralee.
More than 100 businesses in Tralee will be putting out hanging baskets and flower boxes.
Last year, Tralee won a silver medal in the Tidy Towns competition and is hoping to get one better this year.
