Ged Wilcock has announced his retirement from the position of buyer for green and garden goods after 33 years at Grosvenor, with effect from June 17.
Subsequently, from June 1, home and garden leisure buyer Emma Roberts has been promoted to buying manager, with overall responsibility for the buying department.
Pete Davies will assume the role of plant buyer alongside his continuing management of the Planteria team.
The company is in the process of recruiting an assistant/trainee buyer to work alongside Ms Roberts, Mr Davies and Grosvenor's current buying assistant Sophie Marland.
Managing director Iain Wylie said: "It goes without saying that Ged will be greatly missed here at Grosvenor. His contribution over those years has been immeasurable. I would like to thank him for everything he has done for Grosvenor and wish him a long and happy retirement.
"I would also like to congratulate Emma and Pete on their new appointments and I am sure they will bring their considerable talents to their new roles and wish them every success."
Mr Wilcock said: "It has been an extremely difficult decision to walk away from an industry that I have loved being a part of throughout my career. I will not only be leaving behind a job I love, I will also be saying goodbye to many friends in the industry."
