RBGE, working with the Scottish Allotments & Gardens Society, plans to recruit and train a group of volunteers and create a demonstration allotment to show members of the public how to grow their own fruit and vegetables.
The garden's head of exhibitions and events Ian Edwards said: "The aim of the project is to encourage more people to feel confident in growing their own fruit and vegetables at home.
"We are doing that by recruiting and training a group of volunteers who will engage with the public and also through an area of the garden - we are changing that so we can use it for demonstrations.
"We will be producing a very simple manual and eventually creating a mobile kitchen to follow the whole process from plot to plate."
The project coincides with plans for a new fruit garden designed by student Terry Griffiths and overseen by RHS Susan Pearson Bursary recipient Erica Randall.
Randall said: "The garden will be a resource for both professional and pleasure classes and for the general public.
"At the moment, we are removing what's there and putting in hard landscaping and we expect everything to be planted up by autumn."
