Industry figures supplied to Horticulture Week suggest outdoor plant sales were up four per cent for the month, which was knocked by a fall of 30 per cent in the final week when heavy rain fell.
Overall sales for the last week of the month were down four per cent, with the month up about two per cent on last year.
Alton Garden Centre director Andy Bunker said: "Our plant area is plus 10 per cent for September but year to date still - 17 per cent. It’s a shame because September plant sales were looking much more like + 20 per cent with a week to go but the rain put paid to that."
GCA chairman and Garden Centre Group regional manager Peter Burks said: "Until the second last weekend of the month we were in double digit growth but then there was flooding in the North East and that dented the month overall.
Sales for the last week of September saw aquatics up two per cent, books up four per cent, Christmas up 10 per cent, clothing up 25 per cent, craft down 15 per cent, food up 20 per cent, furniture down 30 per cent, garden sundries down 23 per cent, gifts up two per cent, houseplants level, machinery up 15 per cent, outdoor plants down 30 per cent, pets level and catering up five per cent.
