Organisers of a major flower show in the region are sending out a message for a bottle - or 2,000 of them to be precise - so they can show gardeners how to build a greenhouse from recycled household waste.

A team at the 2013 Harrogate Spring Flower Show are collecting two-litre plastic drinks bottles which will be used to make a full-sized two-metre by three-metre greenhouse.

They will construct it during the event, which runs from April 25 to 28 at the Great Yorkshire Showground in Harrogate, North Yorkshire, but first need to collect the thousands of plastic bottles required.

Show director Martin Fish said: "Plastic bottle greenhouses are popping up all over the country and can be used very successfully to grow a wide range of fruit, veg and plants.

"We thought it would be a great way to get more of our visitors involved with recycling and give them a new skill to take away and try at home.

"We think we are going to need about 2,000 bottles to make a full-sized structure and so we are appealing to the public for help to collect enough."

Peter Murphy, from Groundwork North Yorkshire which will run the sessions, added: "We can use both clear and green two-litre plastic bottles, which are then slotted on to ordinary garden canes and fit into a wooden frame to create the greenhouse.

"There are many imaginative and useful ways to recycle plastic bottles, rather than simply melting them down, and building a greenhouse to grow your own plants is one of the most productive."

Organisers are asking people to donate used bottles at one of three drop-off points - the car park at the Regional Agricultural Centre on Railway Road, Harrogate, Groundwork Leeds at the Environment and Business Centre on Merlyn-Rees Avenue in Morley or Groundwork North Yorkshire at Selby Civic Centre, Doncaster Road, Selby.

Other attractions at the 2013 Harrogate Spring Flower Show include more show gardens than ever before and more than 100 plant nursery displays.
