Green-fingered primary school children were treated to a day at the Prince of Wales' family home after beating close to 200 schools to win a national gardening competition.

Little gardeners from Poplar Primary School in Wimbledon won a day in the gardens of Highgrove House in Gloucestershire on Friday after two years planting and nurturing their school garden.

The Mygrove competition invited pupils from years five and six around the country to write an online journal describing how they were learning to grow fruit and vegetables at school.

More than 30 children aged 10 and 11 enjoyed a day at the royal residence, with a treasure hunt in the Walled Garden where Prince Charles grows his own fruit and vegetables.

An art class by teachers from The Prince's Drawing School and a cooking lesson from Borough Market chef Jenny Chandler to show the children how they can cook what they can grow also formed part of the day's activities.

Jo Pfeifer, learning support assistant and gardener at the primary school, said: "It was absolutely fantastic.

"They had a private tour of the beautiful, peaceful gardens enjoying the fountains and the wonderful views, then learned how to make a fresh and tasty salad from the allotment.

"The children also created stunning oil pastel sketches in the Highgrove orchard."

The competition was judged on creativity, how often the blog was updated, work completed in the garden and how much pupils entered into the Mygrove 'spirit', taking on Prince Charles' interest in sustainability.
