The German company, which launched in the UK in 2011, has added two members of staff to its existing team, covering operations and regional sales.
Former Solus buyer, Tony Loftus has joined the team as UK operations manager and brings experience, including 10 years working in a logistics and distribution management role. Sales agent for the southeast, Miles Cleall, was appointed earlier on in the year.
The pair join southern area sales manager Lee Squires and northern area sales manager Tom Stolworthy, who both joined the team in 2013.
Jude Beharall, who heads the UK operation, said: "I am delighted to welcome our most recent team members. Tony and Miles bring a fantastic blend of experience and enthusiasm, which fit well with our strategy for growth.
"The 2014/15 season is going to be really exciting with the launch of three new products, which will strengthen our portfolio of high performance products."
The company opened its first UK office in June, based in Birmingham, which will act as a base for the team and also as a showroom to highlight the wide range of products and display options available to retailers.
In September, the company will exhibit at garden retail show Glee 2014 where it will launch products that it says harness the benefits of mycorrhiza fungi.
