Chief executive Mark Pearson said:
"Despite the challenging times, Gardman has continued to grow in the UK and has exciting plans for the future.
"Tim has made a major contribution to this success as he has been driving improvements in sourcing and supply and sales and marketing. It is now the right time for us to make the appointment of a focused managing director as part of our ongoing investment in the UK market. This includes Tim retaining overall responsibility for international sourcing."
Having joined Gardman in August 2009 as commercial director, Stainton has been responsible for product and category innovation including wild bird care, garden decoration and "homestyle", water features and candles.
Tim Stainton said:
"We’ve grown to a £80 million company and we’re focussed on business growth in all our channels including the large group garden centres and the DIY multiples, and we also plan to build upon our historical strength in the agency-based independent garden centre business.
"Another important focus for us in the future will be strengthening our supply chain performance including product quality control, factory standards and stock availability, and in particular we will be seeking to guarantee peak seasonal demand. It’s also my aim to continue with the strategy of new product and category innovation that has been so successful. We are very confident for the future, even in these trying economic times."
In December 2007 Barclays Private Equity acquired a major stake in Gardman.
