Year to date garden centre sales figures to the end of October now run at minus nine per cent.
Compared with 2010 however, October 2012 was just one per cent down.
HTA marketing director Andrew Maxted said: "Anecdotal comments from garden retail members show encouraging sales of Christmas ranges which a present an opportunity to make up some of the lost ground from earlier in the year and provides a chance to go into 2013 on a positive note.
"The sector can also draw comfort from the knowledge that the industry has previously rebounded from weak years such as the one we have experienced in 2012."
He added: "Consumers will no doubt be looking forward to getting out in their gardens next year and this should be helped by the small but encouraging signs in the economy."
Garden Centre Association figures put October sales figures at 0.4 per cent down on 2011.
