Gardeners’ World presenter Joe Swift is to champion the work of a cancer charity at the RHS Chelsea Flower Show on 22-26 May.

Joe Swift will build his first Chelsea garden in May

Joe is designing the Homebase Teenage Cancer Trust Garden, a plot that he has been crafting since summer 2011.

The “urban oasis” will be his first attempt at a Chelsea masterpiece.

It will see Joe go head-to-head for Chelsea gold with Irish celebrity gardener Diarmuid Gavin, who is designing The Westland Magcial Garden, which promises to be the “tallest and most unusual” at Chelsea this year.

Joe told AG: “I am very excited about it. I know it’s going to be exhausting but I’m looking forward to it.

“This will be a stylish garden in a natural form with timber, stone and water. It aims to connect the urban and suburban homeowner.”

Joe will use giant beams to manipulate visitors’ views through the garden.

Homebase’s partner, the Teenage Cancer Trust, aims to improve chances of survival for young people with cancer aged 13 to 24.

It builds specialist units in NHS hospitals where sick youngsters are treated by cancer experts.

Joe summed up: “The garden will highlight the Trust’s work in a positive way using greenery, colour and planting, so visitors are relaxed and stimulated by the outdoor space.”

Asked about competing with Diarmuid, Joe said: “I don’t see it like that. I’m just there to build the best garden I can for Chelsea.”
