Head gardener Hilary Wood is helping design the garden for Springfield Special Needs School in Witney and a team of palace gardeners have volunteered to help build it.
Blenheim Palace’s head of human resources, Sarah Morris said: "The school make several visits here each year and are always looking at innovative ways to provide amazing new learning opportunities for their pupils. The entire team here is delighted to be able to support their endeavours.
"We are particularly excited to be involved with the garden project and Hilary and her team of volunteers are looking forward to getting on site to help out with the design and planting."
The school educates children aged two to 16. All of the pupils have severe learning difficulties and communication problems.
Fundraising and communications manager Lisa Benson said: "Pupils and staff love coming to Blenheim and we feel very privileged to have this amazing space on our doorstep. To be able to access their amazing gardening skills and experience is an even bigger bonus.
"Our secondary age pupils spend a lot of time in our school garden. It’s a key part of teaching essential life skills to ensure that our pupils can live as independent and fulfilling adult lives as possible.’
The fundraising is part of a series of events and activities to support local groups and charities currently being undertaken by Blenheim Palace.
