Managing director Wayne Eady said: "We are going to have a week of celebrations on the week commencing 11 July where we will invite local people, staff, customers and suppliers to get involved with some projects.
"The aim is to promote the company and celebrate the fact that we have got to 50 years. We will hopefully be inviting along a member of the Delamore family."
Eady bought the company three years ago with two independent partners, putting in place a new managerial structure and sales and marketing team.
He said: "We have recruited a bigger sales and marketing team and we are putting more effort into marketing our own genetics.
"Because parts of our customer base, such as the small growers, are starting to reduce we are beginning to produce stuff for the retail market through the hardware store Wilkinson. I think we have to focus our developmental potential towards the markets that are developing."
