Golding replaces Tommy Gill at the German-owned garden care company that supplies garden centres with products such as Baby Bio. Gill left suddenly at the end of May.
Bayer head of business planning Colin Golding then took over as acting head of Bayer Garden.
Gill told Horticulture Week earlier in the year "business for January and February has been a disaster".
Bayer says now: "Sales have grown as a result of the introduction of new products, innovative new packaging and creative and effective point-of-sale solutions. As a consequence of these initiatives, Bayer Garden has seen its market share grow in key product areas including weedkillers, fertilisers and rose care."
Speaking about his promotion and strategy for 2010 and beyond, Golding said: "2009 has been a successful year for Bayer Garden; we have seen our initiatives deliver good results.
"My strategy looking forward, therefore, is simple. We will defend our position in product categories where we are already the market leader, for example slug killers and insecticides. At the same time, we will concentrate on growing our market share in categories where we have significant product advantages, for example, weedkillers.
"This year we introduced an innovative point-of-sale system, the Baby Bio Tower, which has boosted sales of Baby Bio. We have introduced an organic Slug Bait to complement our market leading Bio Slug & Snail Killer, giving retailers a complete solution for the category. We have also simplified our packaging, using images to explain purpose and method of application. These initiatives were led by our understanding of shoppers and have delivered excellent sales.
"We will continue this investment in product development and packaging innovation throughout 2010 at the same time as maintaining a high level of service to our customers.
"We will continue to work closely with our customers to ensure a sustainable and profitable business for both parties."
In 2000, Bayer acquired PBI Home & Garden to form Bayer Garden. Prior to the acquisition Golding was head of the technical, product development and regulatory functions at PBI. After the acquisition and a period running his own consultancy, Golding joined Bayer Garden as head of business planning.
