Trainees can choose from two types of bursaries. The first is a 14-month placement with a £12,000 bursary where trainees are given practical work-based training in specialised accredited modules, with an emphasis on standards of excellence.
The second is a threeto four-month placement for the new qualification - the Lantra level three heritage horticulture award - with the same bursary paid on a pro rata basis.
Both courses, developed by HHSS, provide a qualification for specialists in heritage horticulture through member gardens across Wales. HHSS said they are the first awards of their kind designed to combine a real understanding of plant life and gardening with a thorough knowledge of history.
HHSS has been in existence since 2010 and has trained more than 50 students. The 2015-16 course will be the last year in which trainees will be able to benefit from the associated bursaries, so chair Andrew Dixey is urging applicants to come forward to make the most of the opportunity.
"This scheme focuses on the practical side of horticulture and offers an opportunity to hone your skills to become specialised," he said. "It is the last year we will able to offer financial support so we urge anyone interested to get in touch as soon as possible - places are limited."
The closing date for 14- month applications is 31 August, with interviews in the second week of September, and starting on 22 September. Email info@HHSS.co.uk for an application form.
