Celebrity TV gardener and Chartered Horticulturist David Domoney is Thrive's first gardening ambassador.
He is joined by Kent-based garden designer Mark Lane, who is the UK's first BBC TV gardening presenter in a wheelchair.
David is very proud to support Thrive in a variety of ways and says gardening helps cultivate hope and wellbeing.
Mark is passionate about good garden design that suits everyone and wants to show what disabled people are capable of. Like Thrive, he looks at the 'ability' in disability.
Kathryn Rossiter, Thrive CEO, says: "We are thrilled to have both David and Mark championing Thrive. Both are passionate supporters of the cause and understand the
benefits of gardening.
"Mark will also be working with our training team to further develop the course we offer to garden designers to take into account accessibility when designing a garden."
David co-presents with Alan Titchmarsh on ITV1 show 'Love Your Garden’ which gives surprise makeovers to the outdoor spaces of some especially deserving people. He is also the regular garden expert on ITV1's This Morning.
He is also an award-winning gardener with 28 RHS medals and is a Fellow of the Institute of Horticulture.
David said: "So often people feel daunted by gardening, but working with Thrive, I want to inspire people to get outside and have a go. No matter who you are or where you live, you can still bring a touch of nature into your home.
"I am delighted to be the Thrive ambassador for gardening, promoting the great work they do whenever and wherever I can."
Mark said: "Garden and landscape design should be inclusive by default, but it is rare. At Thrive's garden near Reading I was delighted to see how productive the walled garden is, how social a space it is, but above all how horticulture and gardening are changing lives.
"I truly believe in what Thrive does and am looking forward to supporting them and championing their work."
