The Manchester-based mail order bulb and plant retailer’s turnover was £20.07m for the year ended 30 June 2014, compared to £16.82m for the previous year.
Operating profit was up to £547,301 from £445,722.
Directors, the Duiker-Parkers, said business had been "exceptionally good" thanks to good weather and increased market share, leading to a record turnover which rose by 19 per cent. Profit was up 22 per cent.
The company relaunched its Anwick garden centre, in Sleaford, Lincolnshire in March. It also has garden centres in Flixton and Prestbury.
It said risks were competition from local and national competitors, poor weather and rising supply product costs.
