Regional account managers Andrew Dunkley and Phil Tremayne will attend the show, on June 7 and 8, to promote APL and explain to visitors the benefits of choosing an accredited landscaper and the Government-endorsed Trustmark scheme, which all APL members must sign up to.
The new design-led event was created by Sheffield-based horticulturalist and former TV producer Richard Nicolle, who has five years' exhibition experience at the RHS Hampton Court Flower Show, and has also worked on the Sheffield Winter Garden and Peace Gardens.
He said: "The presence of the APL at Garden Up will help to underline the importance of qualified and creditable professionals in the gardening and landscaping industry. Sheffield is a vibrant city with a great many gardens and green spaces and we feel that to live up to its reputation as the greenest city in Britain, it needs a thriving horticultural design sector behind it.
"The Garden Up event is helping to stimulate an appetite for gardening expertise and inspire the market with innovations and skills that can be applied to our gardens and built environments."
The presence is in addition to regular dates for the APL, including Gardening Scotland, Hampton Court, Tatton, Landscape and The Skills Show.
APL chairman Mark Gregory said: "2014 is an exciting year for the APL with the partnership with WorldSkillsUK, collaborative work with Trustmark and Your Garden, Your Budget at RHS Hampton Court. We are delighted to be able to add Garden Up to this list."
