A representative said: "Jim Hagedorn has removed a layer of management from Scotts Miracle-Gro to increase the speed of decision-making and to cut costs. That means Martin Breddy has left the company."
His role as Scotts Miracle-Gro vice-president and general manager of the UK and Asia Pacific spanned two worldwide regions. Australia, China, France and other world markets now report directly to Scotts' head office in the USA.
Scotts said: "Martin leaves us on a high in his personal career, having been pivotal to the thriving position of Scotts Miracle-Gro in the UK, culminating in the highly successful acquisition of the Solus business last year. We wish Martin every success in his new ventures."
In the USA, Scotts Miracle-Gro president and chief operating officer Barry Sanders departed the company on 31 January.
Since the beginning of 2014, the Scotts Miracle-Gro Company has eliminated approximately 25 per cent of its leadership roles at the senior vice-president level or higher.
Sheila Hill has replaced Breddy as UK general manager. She started at Scotts 18 years ago as lawns brand manager. More recently, her role was vice-president and international marketing lead, working on new product development, strategy and marketing plans across all the European countries.
There are no changes to the local sales and marketing teams, which continue to be led by Rainer Schubert and Paula Parker respectively.
