Each year, Garden Retail Award-winning Fermoys works with local primary schools to design and grow vegetable gardens for its Wheelie B Competition.
This year, more than 40 schools will be taking part and the winning barrows will be displayed alongside barrows made by the Chelsea Pensioners in their garden for the Chelsea Fringe event.
Fermoys company development manager Sarah Dumont said: "Working with Scotts Miracle Gro and Peter Seabrook on their Love the Garden project at Chelsea, we thought it would be fantastic to display some of the barrows that local schools are designing for the Garden in a Wheelbarrow competition.
"I had a flash of inspiration and decided that it would be great for us to cycle a barrow up to Chelsea visiting other garden centres on the way and trying to raise awareness and money for both Greenfingers and the Gardening Leave charity supported by Scotts that improves the mental and physical well-being of service personnel, using horticultural therapy, in walled gardens."
Murdoch is looking for sponsorship from garden suppliers and manufacturers as well as volunteers along the way to help cycle. See www.justgiving.com/wheelbarrow-ride.
