Managing director Neil Stevenson attributed the success to a new orchid production facility, which the Grower of the Year Award recognised, coming fully into operation.
Stevenson said: "We got some good feedback from the award and it was duly noted by some of my important customers."
He added that the boost in sales had been especially welcome considering the economic climate.
The deadline for entry to this year's awards, run by HW and Grower in association with Asda, the HTA and the NFU, is just one week away - Friday 6 November.
