The HTA said businesses must target customers with tailored offerings and harness social media such as Facebook to enhance their word-of-mouth marketing.
HTA Director of Marketing and Communications Andrew Maxted said: "The garden industry has made the most of the mild autumn with core garden sales doing well. With increasing numbers of younger consumers taking an interest in their gardens this bodes well for underlying demand next spring."
He added: "While the uncertainties in the Eurozone and the wider economic outlook are concerns for all of us, the garden industry is resilient and we can look forward to a boost from the Queen’s Diamond Jubilee and the London Olympics in 2012."
Along with the figures from the association’s Garden Retail Monitor the HTA Market Update presents data from the BRC KPMG Retail Sales Monitor and provides a summary of consumer confidence indices, UK house prices and weather data from the met office.
