Westland said: "The trading results and period-end financial position were considered to be satisfactory. The directors believe there are still opportunities for growth as new lines are introduced to the growing media and fertiliser markets.
"The directors have plans in place to ensure the group is strongly placed to retain its market position and continued profitability."
During the period Westland acquired the trade and assets of William Sinclair Plc, sold out of administration in July 2015, and the share capital of Westland SPZoo.
