During his time at Hillier, he created 25 Gold-Medal winning RHS Chelsea exhibits, led Hillier Gardening Club tours around Britain and Europe, gave frequent gardening talks to gardening groups and industry bodies, wrote many of the bestselling Hillier Gardener’s Guides and was the principal media spokesperson for Hillier.
Robert Hillier, chairman of Hillier Nurseries and Garden Centres said: "Andy has played a tremendous role in Hillier’s success. I would like to express my sincere thanks to Andy for his outstanding contribution over the past three decades."
Andrew McIndoe said: "It has been a great honour and a pleasure to be a part of the Hillier story for so long and to have worked so closely with such an enthusiastic, knowledgeable team. I am excited to now be able to focus on what I am most passionate about, which is communicating, educating, designing and enthusing about the wonderful world of plants and gardening."
Chris Francis took over Hillier Garden Centres last year from McIndoe. After a restructure, Francis will report to chairman Robert Hillier along with directors wholesale nursery manager Kevin Hobbs and trees manager Hossein Arshadi.
Hillier will do Chelsea in 2016 but a designer is to be announced.
McIndoe is to concentrate on writing, lectures, My Garden School and designing.
