Garden Connect was previously equal partner in the business, providing IT support and systems but has now set up offices in Luton from where it will run the company.
Managing director Edwin Meijer said: "The reason we are taking this step is that we believe we can offer our clients an even better range of online services and support. The online world is changing rapidly and with a team of 15 developers, marketeers and designers to rely on we are able to create more advantages for our existing and new clients."
The company will be re-branded as Garden Connect. Eimert de Graaff will withdraw from the company, and Stephanie Burniston has been appointed as account manager.
Edwin Meijer will work from Luton two days a week from 1 January 2013.
Meijer said: "Our team is working hard every day to create new, exciting services. The roots of Garden Connect are Dutch and we are coming from a mature and competitive market where we have to keep up the pace of developments to stand out.
"We firmly believe independent garden centres of whatever size, can and should benefit from the opportunities the internet has to offer to every business. We are fully committed to bringing our success and full range of services to the UK.".
