GCA chief executive Gillie Westwood said applicants must have been accepted to, and must be intending to complete, horticultural study at a college and must want to work in the garden retail industry.
She added: "We're not getting the candidates, which we find amazing, especially as there is talk of raising tuition fees."
The GCA Trust gives £1,500 per annum to two students who have been accepted to HND, diploma or BSc courses and are returning to, or preparing to, work in the garden-centre industry.
A current student is Pershore College BSc horticulture student Carl Berthold, who graduates this summer. Berthold is already working part-time at Webbs Garden Centre in Wychbold, Worcestershire.
Money goes towards accommodation or fees, and the GCA is now looking at awards for part-time students. GCA trustees are Daisy Nook, Barton Grange, Millbrook and Van Hage garden centres.
