GCA chairman Will Armitage says he is focussing on the positives after a bank holiday weekend washout at his two West Yorkshire garden centres.
Armitage's was 15-20 per cent down over the weekend after "Yorkshire monsoons" but he is five per cent up for May so far and 15 per cent for the year compared to 2013.
Armitage said: "I'd like to think we'll see the double digit sales increases of last June and July but I don't think we will though we'll still come out at the end of the year well."
Ayletts, Stewarts and Hillview Group all reported fair bank holiday sales, with GCA chief executive Iain Wylie saying the weekend was "hit and miss".
Some retailers said shortages of outdoor living products allied to supplier Solus going into administration could harm end of season sales.
