Garden centre sales leapt in outdoor and watering categories last week, according to figures supplied to Horticulture Week.
Garden furniture sales were five times the equivalent week in 2012 in the week to 14 July.
Watering sales were 400 per cent up, while compost and pots were double the equivalent week in 2012, which was mostly rainy and cold compared to last week's hot, dry weather.
Aquatics were two per cent up, books were 20 per cent down, clothing was 33 per cent up, craft was 18 per cent down, food was three per cent down, furniture was 500 per cent up, sundries were 30 per cent up, gifts were 15 per cent down, houseplants were two per cent down, outdoor plants were 25 per cent up, pets were 20 per cent down and catering was 18 per cent down.
Overall sales were 30 per cent up on the same week last year.
GCA chairman Peter Burks said: "Business has been good. Watering has been off the scale and plant and compost sales have been good."
GCA interim chief executive Iain Wylie said: "There's a lot of relief around and a degree of positivity. Weather has been the largest driver and not the more serious problem of not having customers who want to buy the products we sell.
"There was a lot of positivity at Solex because from 10 days before everyone had strong sales on furniture. Everyone has a smile on their face and are more positively preparing for next season on a stable footing."
