Glee runs in September at the NEC Birmingham and this year will be held September 14-16.
Glee at Spring Fair 2018, also at the NEC, will show products in hall three in garden care, landscaping and garden decoration, and outdoor entertaining.
Glee event director Matthew Mein said: "Retailing is a constantly evolving business, and we appreciate that the buying cycle for gardening, outdoor living gifts, and design-led products stretches across the whole year.
"However, in the Glee 2016 post-show visitor survey over 15% of those polled said that they would also make purchasing decision in first quarter of the year.
"What is more, we hope that Glee’s Spring Fair presence will increase the show’s visibility to those buyers that don’t normal attend the September show. This will give our exhibitors an additional sales opportunity in the year."
