Children's ideas are central features of the Stepping Forward garden

Youngsters at St Brigid's School in Denbigh have worked alongside Fforwm Tirlun, which supports landscaping, to make the Stepping Forward garden.

It will go on display at the Royal Horticultural Society (RHS) Show at Tatton Park, Cheshire, this month.

Experts praised the pupils' "great and unusual ideas". After judging, the garden will be replanted in the school.

Fforwm Tirlun has entered a garden at the RHS Tatton show for the past three years, but this is the first inspired by children.

The idea to enter developed after representatives of the school visited it last year.

One, Steve Emery, a parent and landscape gardener, said: "Two of us were going round and between us we thought what a good idea to get the school involved with a project of this type and it just grew from there".

He told BBC Radio Wales' Country Focus that the project became hard work in particular in the couple of months before the show.

"Because we've got the children involved we want to make sure that they play an active part," he said.

"But I think we have a lot of people to come up and bring the show together."

The children's garden is in the back-to-back section of the competition. A key feature is a copper tree whose leaves are stamped with the children's names, and other elements include the creation of a chequerboard lawn and an integrated dolls' house that could itself be landscaped by a child.

Paul Page, a Welsh College of Horticulture lecturer who also works for Fforwm Tirlun, said it was "all very much designed around the imagination of children".

"Charlie and the Chocolate Factory was on at the time and there were lots of chocolate rivers," said Mr Page.

"There were some really great ideas and quite unusual.

"Elements came from lots of different gardens. It has to be practical at the end of the day because it is going to be a real garden."
